CA2577202C - Capturing a user's design intent with resolvable objects - Google Patents

Abstract

Software for designing interior and/or exterior spaces efficiently ensures that user intent is captured in a timely, practical manner. When a user creates an input, such as selecting a shape of a table to put into a design space, the design software creates an initial object that is managed as part of a data structure. Generally, the initial object includes a type element having one or more options.. Program code in the created initial object determines an appropriate option based on any number of factors including, but not limited to, elements of the user's original input. A subsequent child object with a set of independent program code is also created, which has as its type the option determined from the previous initial object. The subsequent object also determines its options based on attributes of the user's input, and creates any additional child objects where appropriate.

Description

CAPTURING A USER'S DESIGN INTENT
WITH RESOLVABLE OBJECTS
BACKGROUND OF THE INVENTION
1. The Field of the Invention This invention relates to systems, methods, and computer program products for modeling the design of commercial and residential interiors, and related spaces.

2. Background and Relevant Art As computerized systems have increased in popularity, so has the range of applications that incorporate computational technology. Computational technology 1o now extends across a broad range of applications, including a wide range of productivity and entertainment software. Indeed, computational technology. and related software can now be found in a wide range of generic applications that are suited for many environments, as well as fairly industry-specific software.
One such industry that has employed specific types of software and other computational technology increasingly over the past few years is that related to building and/or architectural design. In particular, architects and interior designers (or "designers") use a wide range of design software for designing the aesthetic as well as functional aspects of a given residential or commercial space. In some cases, the designer might use some software programs that might be better suited for exterior design, and then use other software programs that might be better suited for interior design. For example, a designer might implement one software program to design an overall look of a building, and then use the software to design or position each of the functional components of the building, such as weight-bearing walls, trusses in a roof, positioning of electrical outlets, and so on. The designer might then use another software program, whether separately, or as an add-on to the first software program, to design functional walls for offices, design where to place work stations, design the position of desks, chairs, lamps, and so forth.
When designing the exterior and/or interior of a given residential or commercial space, the designer will ordinarily need to take care that each of the elements in the design are structurally sound when built. This is because typical design software allows spaces to be fairly configurable to suit the user's tastes without specific regard in many cases to whether the design will actually work. For example, one typical software design program might allow an architect to design a roof or ceiling that is ill-suited for the number or type of weight-bearing walls the architect has presently drawn. If the roof were actually constructed as designed by the architect, the roof or ceiling might collapse. In a situation such as this, however, the builder might indicate to the architect that the design is physically impossible or impractical, and ask for a redesign. This, of course, can lead to any number of inefficiencies.
Part of the problem with many design software programs that can lead to designing physically impractical structures is the notion that many such design problems require some drawing of a space in flat, two-dimensional space. For to example, the outside of a building is designed in a view that emphasizes primarily only height and width, while a top ("plan") view of a building is designed in a view that emphasizes primarily only length and width. With views such as these, the designer will either need to independently visualize the three-dimensional spacing, or will need to perform a separate rendering of the design, if the software allows for it.
is While three-dimensional rendering is available in some design software, three-dimensional rendering is fairly processing or resource intensive, and can take an additional amount of time. Furthermore, while three-dimensional rendering does allow the designer to "travel" around a design, such as an office, conventional three-dimensional rendering in design software does not typically allow the designer to 20 peek around doors, look under tables, travel through hallways, or look up at ceilings, and the like very effectively. Three-dimensional design software also does not ordinarily accurately capture other natural variables that might affect the positioning of lamps, desks, or computer monitors based on the directly or spread of available natural light, and so on.
25 In addition, neither the three-dimensional rendering nor the two-dimensional drawing views are designed to accommodate necessary modifications to the objects or walls, based on real-world materials, or other important constraints. For example, a designer might place several L-shaped desks in a work space that are to be arranged back to back against a cubicle wall. In an ordinary environment, positioning the L-30 shaped desks together might involve a next step of removing a leg where one leg might be shared, or removing a bracket from one of the L-shaped desks for similar reasons. Accordingly, both the two-dimensional views and three-dimensional

3 renderings of conventional design software captures only what is entered, and requires the designer to add or remove parts in a specific drawing to reflect real-world, usage.
Once a design has been finalized by, a designer, the designer will need. to generate one or more parts lists that are reflective of the various dimensions and parts place in any, of the design. views. The parts list will be used for any number of cost estimate or ordering ends. Unfortunately, there is generally not a convenient way for an accurate parts list to be generated automatically from one or more design views.
For example, even though a designer might use a conventional design software program to design one or more views of a space, the designer might need to to independently deduce a parts list based from each of the views. In some cases, the designer might hire another person to identify. each part, including wood or sheetrock for each wall, as well as the number of brackets or screws needed for each door hinge, desk mount, and the like.
Although there are some software programs that can produce parts lists from generated view, the parts lists are not always accurate. For example, in the case where two L-shaped desks will be adjoined in a work space, a conventional parts list that interfaces with the design software will not ordinarily be able to deduce the correct, specific amount of parts needed for each environment, such as in the case of shared components. Furthermore, the parts lists that are generated are difficult to read, and usually comprise some detailed information in text, or in a stock keeping unit ("SKU"), and do not readily inform the reader exactly.. what the image looks Iike.
Thus, conventional, automatically generated. parts lists must often be edited-in painstaking fashion before they can be submitted to an order fulfillment company.
Accordingly, an advantage in the art can be realized with systems, methods, and computer program products that provide a designer with the ability. to design spaces in a highly configurable, and yet user-friendly manner. In particular, an advantage can be realized with expert systems that are interoperable with other systems, and are configured to specifically capture a designer's intent in a manner that emphasizes physically possible or practical configurations.
BRIEF SUMMARY OF THE INVENTION
The present invention solves one or more of the foregoing problems in, the prior art with systems, methods, and computer program products configured to automatically resolve a user's design choices in real time. In particular,

4 implementations of the present invention relate to the creation of program objects, in response to user input, where the program objects are configured to continually and automatically resolve a user's design choices in real-time and in consideration of real-world scenarios.
For example, a method in accordance with an. implementation of the present invention includes creating an initial object based on user design input, where the user input has one or more attributes. The initial object also includes an initial type that relates to the one or more attributes. For example, a user selects a rectangle table to place into a design space, and the design software creates an object having "table" as to its type. The method also involves determining, an initial option for the initial type based on any of the one or more attributes. For example, the table can include options for a circular or rectangular shape. Program code of the "table" object can then determine an appropriate shape option based on any user input for present or subsequent values, such as a type of material that should be used for other elements of the table.
. The method also involves creating a subsequent object based on the determined initial option, where the determined initial option provides a basis for.
subsequent type for the subsequent object. For example, once the rectangle options is determined for the initial table object, the design software creates another child object in the data structure that has "Rectangle Leg" as a type, and further has another set of options to be determined, such as for type of legs. The method further involves determining a subsequent option for the subsequent object based on any of the one or more attributes of the user input. For example, the "Rectangle" type object may have additional sub-options that would be used in other child objects, such as type of material or color, which can be considered by the program code in determining the leg option for the "Rectangle" type object. Thus, program code of the new object can make determinations of present options for the corresponding object based on any number of factors.
Along similar lines, a data structure in accordance with an implementation of the present invention includes a first object in a data structure created in response to a first user choice having one or more attributes. The first object has a first type component and a first option component that is determined by a set of program code in the first object based. on the one or more attributes in the user input.
The data structure also includes a second object that is related to the first object in the data structure. The second object includes a second type component that is based on the first option component of the first object, and a second option component that is determined by a set of program code in the second object based on the one or more

5 attributes. The first and second objects are configured to independently resolve the corresponding type and option component of the first or second object based on an evaluation of one or more user design choices.
Accordingly, design software in accordance with the present invention provides for the creation of several independently resolvable. objects in a composite 1o data structure, each of which is configured to resolve one-or more specific elements of a user's design choice. The objects automatically resolve prior, present, and ongoing user input, as appropriate, so that the user's. design choices are represented in a physically or materially-possible way.
Additional features and advantages of exemplary implementations of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of such exemplary implementations. The features and advantages of such implementations may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features will become more fully, apparent from the following description and appended claims, or may be learned by the practice of such exemplary implementations as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention extends to systems, methods, and computer program is products configured to automatically resolve a user's design choices in real time. In particular, implementations of the present invention relate to the creation of program objects in response to user input, where the program objects are configured to continually and automatically resolve a user's design choices in real-time and in consideration of real-world scenarios.
20 For example, as will be understood from the present description and claims, one aspect of the invention relates to associating user input with a software object that includes type and option components. Another aspect of the invention involves automatically creating child objects based on one or more selected option components of the prior parent object. Still another aspect of the invention relates to ensuring that 25 user selections accord with real-world values in real-time, such as by implementing program code in each of the parent and child objects in a data structure, which compares present user input with attributes from prior or original user input.
As such, it will be understood that each object in the data structure can be configured to resolve itself, and that user input at one level in the data structure is appropriately propagated 30 throughout other objects in the data structure, thereby continually resolving user input in an accurate and consistent manner.
In particular, Figure 1A illustrates a data structure in accordance with at least one implementation of the present invention in which one or more objects. have been

7 created in response to user input. In particular, Figure 1A shows a data structure 100 having objects 105a, I I Oa-d, 115a-d,. and 120a-d-, which are created based on a user selection of a table in a design space. For example, in a design software program in accordance with an implementation of the present invention, a user can select.
a table icon in a selection area of a user interface, and then "drag and drop" or draw the table into a specific design space. Upon selection, or shortly thereafter, the design software will also create an. initial object 105a for the table, which contains one or more "Type"
and/or "Option" formats. The data from the initial object 105a is propagated throughout additionally created objects in the data structure 100.
For example, Figure IA shows that data structure 100 includes a table object 105a for a rectangular table. The table object 105a is, related to additional child-objects I I Oa-d for each of the four legs of the table. The legs, objects t I
Oa-d in turn are related to material objects 115a-d for the material of the legs.
Furthermore,, child objects 120a-d are related to, and depend from, the material objects 115a-d.
Thus, as will be understood in greater detail in the following description, some objects.(e.g., object 105a) are parent objects, some objects (e.g., 120a-d) are only child objects, and other objects (e.g., I I Oa-d, and I I 5a-d) are both parent and child objects.
For example, as will be understood with more particularity in Figures IC-ID, each of these objects includes at least a "Type" component, and in the case of parent or parent/child objects, also will include an "Option" component. When an object includes a set of possible options (or "option component") for a "type,"
program code in the given object can be used to determine an appropriate option based any, of an attribute of the user's input, and/or based on other reference information from a reference library. (e.g. 115, Figure 1C). The determined option for that object then provides a basis for one ore more possible "Type" components for a corresponding child object. For example, with respect to object 1 l 5a and object 120a, "Material A"
is a determined option for object 115a, and, based on information in the reference library, provides a basis for a type component for object 120a. "Color A", which is a determined option for object 120a, is a possible option for the "Type"
component that is based on the determined option of "Material A" in object 115a.
Some of the data in a given object, however, may not be represented precisely as the user selected it initially through the user interface. For example, the user might select a color or material for a rectangular table that is only available in circular

8 tables. Alternatively, the user might inadvertently position the table icon in a design space in a physically impractical or impossible configuration, such as by placing the table partly on top of a wall line in a 2-D view. As will be understood more fully in Figures 1C-1D, the design. software tries to memorize and/or modify the objects to.
accurately represent the user's design choice. As such, this can cause any of the objects in the initial data. structure (Figure 1A) to select or determine modified, appropriate representations, of the user's initial input. Upon subsequent input from the user, each of the objects may again adjust the representation to allow the user's prior input that was originally modified or ignored in order to make still further to modifications to the user's input for another appropriate representation.
For example, Figure lB shows the data structure 100 of Figure 1A after there has been some change due, for example, to at least some different user input.
In particular, Figure 1B shows.that the data structure 100 now shows that the table object 105b is now representative of a "Circle" table. This change in the initial object 105b has resulted in a corresponding change to the other objects in the data structure. For example, Figure IB shows that there are now five leg objects 113a-e, five corresponding material objects 117a-e, and five corresponding color objects 123a-e that are different in at least one respect from the child objects of Figure IA. That is, the user has now selected a circular table that comes only in five legs, and also comes with a number of other options for material and color that have been resolved by each of the objects. 113a-e, 117a-e, and 123a-e. The objects of Figure lB have therefore made appropriate changes based on one or more attributes of the user's initial and/or subsequent input for material and color.
Figure lC illustrates a more detailed schematic diagram for creating one or more of the objects shown in Figure IA based on user input. In particular, Figure IC
shows that user input 125a includes a request to create a table based on one or more initial attributes 130a. For example, attributes 130a include a request for placing a rectangular table in a design space. Although the user need not necessarily select every possible detail of the table when selecting the table itself, Figure IC
shows that the user has also indicated a preference for "Material B" and for "Color B" to be associated with the table. The corresponding child objects that are then created will attempt to incorporate these user design choices as closely as appropriate.

9 For example, upon receipt of user input 125a, the design software creates object 105a having a type component 153 of "Table". The design software in turn coordinates, with the reference library. 135 to determine that the Type 153 of object 105a should have a set of options 155. In general, the reference library 135 can include all possible types, options, and/or corresponding sub-options that are possible in the design. program based on any number of predetermined factors. These factors can include whether certain materials are available for a component through a fulfillment service, any physical constraints of a component, and so on. The reference library 135 can, also include information regarding positioning of a component, to possible options for the given item when it is placed in a certain position, and so on.
For example, the reference library. 135 can include information that two tables share mounting brackets and one or more legs when they are positioned.in a back to back position.
As such, Figure I C shows that the "Type" component 153 of object 105a includes a set of options 155, which includes a "Circle" option 180 and a "Rectangle"
option 160. Since the "Rectangle" type of table is specified in the attribute 130a, the program code 150a of the object 105a automatically selects. the "Rectangle"
option for this object 105a. In other examples, however, the program code 150a can identify another feature that has been selected by the user, such as the material or color type for the table, such that the program code 150a may actually select a circle table in the initial object 105a based on potential sub-option data, which is a better fit within the design context. Nevertheless, Figure IC shows that the design software creates a new child object 1 l0a based on the previously selected option of rectangle 160.
In particular, the design software consults the reference library 135 and determines that the determined option "Rectangle" 160 has additional sub-options that are to be considered. The design software also determines that the determined option "Rectangle" 160 provides a basis for new object 110a that has a type component at least for "Rectangle Table Leg". One will appreciate that there may be several different resulting "Type" components that are based on the determined initial option of "Rectangle" 160, which in turn will be used as corresponding "Type"
components for a new child object. In this example, only one corresponding child component is shown for purposes of convenience.

For example, Figure IC shows that type 161 in object I10a also has a set of options 163, based on information from reference library, 135, which includes a "Round leg" option 165a and a "Square leg" option 165b. Since the user failed to specify. a type of leg in the attribute 130a in this example, program code 150b in .5 object l 10a automatically determines a default option component of "Round Legs"
165a. In other examples, the program code 150a might identify another feature that has been selected by the user, such as the material or color for the table, such that the program code 150a tries to find a leg in object I10a that can be used within the context of a potential sub-option. Nevertheless, in the present example, Figure IC

10 shows that program code 150b selects the round leg. option 165a.
Upon selection, the design software consults reference library. 135 to identify if any additional "Types" or "Options" need to be propagated to a next child object based on the determined round leg option 165a from object 110a. In this case, Figure I C shows that the "Round Legs" type I65a in object 115a provides a basis for a new object 115a, which has a "Type" component 166 of "Round Leg Material". As before, and based on information in reference library 135, this new type 166 also has a set of options 167 that include "Material A" 170a, "Material C" 170b, and "Material D" 170c. The program code 150c for object 110a then references the user's attributes 130a to determine which of these options. to select. Since the user selected "Material B", which is still a valid attribute at this point, and "Material B" is not one of the available options for "Round Leg Material", program code 150c selects a default option, such as "Material A".
As with objects 105a and I10a, the design software consults reference library 135, and identifies that the determined option of "Material A" 170a provides a basis for still another child object, which has a new type component and set of corresponding options. Accordingly, Figure IC shows that the design software creates child object 120a that depends from object 115a, and which has "Material A
Color" 171 as its type component. Again based on information from the reference library 135, this type component 170a is determined to have a set of options 173 for color, such as option 175a for "Color A", option 175b for "Color C", and option 175c for "Color D".
Program code 150d then refers to the initial attributes 130a to determine the appropriate option. Since "Color B" is not available as an option of the "Material A

11 Color" type 171, program code 150d determines another appropriate color. In particular, Figure IC shows that program code 150d has selected option component 175a for "Color A". As before, the program code can make this determination based on any number of factors, such as the closeness in color between "Color B" and "Color A". Since the selection "Color A" 175a does. not have any additional sub-options in this example, the design software does not need to continue creating any additional child objects. As such, object 120a is the final object in this set of objects stemming from the initial type component of "Rectangle Table" in object 1'45a.
Figure 1D illustrates another detailed schematic diagram of one or more of the objects shown in Figure 1B, or the objects of Figure 1C after receiving additional user input 125b that changes. a datum in any of the object 105a, 11 Oa, 115a, or 120a. In particular, Figure ID shows that the design software receives user input 125b, which includes attribute 130b, and simply changes one initial attribute of 130a.
That is, the user has selected a "Circle Table", which represent a change from the prior selection of "Rectangle Table". As will be understood from the following description, this change in attributes 130a (now 130b) results in a fundamental change in the object 105a to object 105b, which can further result in corresponding additional changes in the following child objects.
For example, program code 150a automatically changes the option selection for type 153, such that the object 105a now has a selected option of "Circle"
180, and hence becomes object 105.b. In contrast with the selected "Rectangle" table option in Figure IC, however, Figure ID shows that the design software consults the reference library 135, and identifies a new set of types and options that are at least partially different from those determined for "Rectangle" table. As such, the design software creates a new child object II3a, having "Circle Table Legs" 181 as its type, and a set of options 183 that include options for "Round Legs" 185a, as well as for "Pentagonal Legs" 185b.
By way of explanation, Figure 1D also shows that object I 13a has a different part number (i.e., "113a") from object I IOa, even though it has the same program code 150b, to reflect that the objects are different in some respects and identical in others in this case. This need not necessarily be the case each time an object is changed or created. For example, the program objects 110a and 113a may be identical objects in nearly all respects except for option selections, or may be entirely

12 different objects using different program code. Generally, the design software can determine whether to create a new object or based on a previously, determined option, or whether to simply reuse and alter a previous object (e.g.,, object 105a changing to object 105b) with new (or partly new) information.
In any event, with the change from rectangular to circular tables, program code 150b of object 113a also determines the appropriate leg. option for the new type 181 by referring to the updated set of attributes 130b. In this case, all that has changed is table style, such that the user's original set of preferences 130a for "Material B" and "Color B" are still. maintained, and there are no indicated preferences for leg type. In this case, therefore, the program code 150b determines that the pentagonal legs option 185b has one or more additional- sub-options for .material, at least one of which is consistent with the previously indicated attribute (e.g., 130a). for using "Material B". Thus, program code 150b selects "Pentagonal Legs" for object 113a. The design software then consults reference library 135 based on the determined option 185b, and identifies that this determined option provides a basis for a new child object, with new type and options components. In particular, Figure 1D shows that the design software generates the next child object 117a with "Pentagonal Legs Material" as the new type 186.
Figure ID also shows that the "Pentagonal Legs" type 186 in object 11 Ta has a set of options 187, which, in addition to "Material B" 190a, also include "Material E"
190b. Nevertheless, the program code 150c automatically selects option component "Material B" 190a based on the current set of valid attributes 130b. As before, the design software then consults reference library 135, and identifies that the determined.
option 190a is a basis for another type and set of options related to material color.
Accordingly, Figure ID shows that the design software then creates a corresponding next dependent child object 123a, which has "Material B Color" as its type 191, which further has a set of options 193. In particular, Figure 1D shows that the set of options 193 include an option 195a for "Color B", and an option 195b for "Color E".
Nevertheless, program code 150d references the valid attributes of 130a-b, and selects option component 195b for "Color B".
Accordingly, the schematic diagrams of Figures ]A through ID show that design software in accordance with the present invention can propagate data associated with user input throughout a single data structure of related objects, where

13 each object determines its match or best fit with the user input. In addition, the schematic diagrams of Figures 1A through ID show how each created object in the data structure can be configured to independently, resolve present and subsequent user input in a manner that is consistent with original user input.
The preceding examples, however, are only one example of how objects in a data structure can change in accordance with multiple user design choices. For example, the preceding, examples can also be applied to physical rules regarding placement of design elements, such as the table or chair. In particular, the design software can also be configured with rules regarding possible orientations, as. well as.
io logical placements. of tables in a design space, such as. by prohibiting a table from an upside down configuration, or from placing the table on top of a wall. It will be appreciated, therefore, that the concepts of limiting. a user selection in one instance, and allowing the user selection in another instance, or vice versa through a common data structure, can be applied to'a wide range of functions with design software in accordance with implementations of the present invention. In particular, the concepts described herein provide at least for continually resolving user input in a manner that is consistent with possible, or real-world, values using a data structure of interrelated, at least partially independently-operating, data objects.
The present invention can- also be described in terms of a functional step and non-functional acts for accomplishing a method in accordance with the present invention. In particular, Figure 2 illustrates, a method having one or more non-functional acts of (and a functional step for) accomplishing a method of automatically, resolving. the user's. design choices, such that the user's design choices can be represented in an accurate way. The acts and steps of Figure 2 are described below with reference to the schematic diagrams in Figures 1A through ID.
As a preliminary matter, Figure 2, the corresponding claims, and the claim text also include some reference to "initial" and/or "subsequent" acts or steps. It should be appreciated, however, that these designations are primarily to suggest positions of sequence at some point in a continuum, such that an "initial" act may or may not be a first act in a sequence, but is at least prior to, a "subsequent" act. In addition, a "subsequent" act need only be after an "initial" act at some point, and is therefore not necessarily immediately after an "initial act". Along similar lines, the terms "first" or "second" (or "third", etc.) typically refer to the first time the relevant component (e.g.,

14 object) is identified, though the component may not necessarily be the first created or first used component, and may not necessarily occur in sequence before a "second or "third" mentioned component. For example, object l i la could be a "first or an "initial" object within the context of a given claim, though object I05b might ordinarily be the first or initially, created object in the given context.
In any event, Figure 2 shows that a method of automatically resolving the user's design choices comprises an act 200 of creating. an initial object based on user input. Act 200 includes creating an initial object based on user design input having one or more attributes, the initial object including an initial type that relates, to the one to or more attributes. For example, a user input 125a includes a set of attributes 130a that reflect one or more aspects of the input, or of the user's intentions.
Based on the user input 125a, the design software consults reference library. 135, and.
creates, an initial object (e.g., 105a) that has a type component (e.g., 153) and a set (e.g., 155) of one or more option components (e.g., 180, 160).
In addition, the method illustrated in Figure 2 comprises a step 240 for generating one or more subsequent objects based on an initial type. Step 240 includes generating one or more subsequent objects based at least in part on the initial type, such that each of the initial and one or more subsequent objects are able to remain updated in real-time despite other user -input that changes any of the initial or subsequent objects in the data structure. For example, a data structure (e.g., 100a) includes one or more parent objects, and one or more child objects (e.g., objects 1 loa-d) that each have a "Type" component that is based on a previously determined "Option" in a prior parent object (e.g., 105a). With reference for example to Figure IA, object 1 lOa has a type 161 that is based on a determined option 160 object 105a, while object 115a has a type component 166 that is based on the determined option 165a of object I I Oa. If a user changes any element of the initial object (e.g., 105a), or of the initial attributes (e.g., 130a), or of data in a subsequent object (e.g., I I5a), each child or parent object in the data structure, in turn, automatically resolves itself in accordance with the new user input.
Although step 240 can be performed by any number or order of corresponding acts, Figure 2 shows that step 240 comprises an act 210 of determining an initial option. Act 210 includes determining an initial option for the initial type based on any of the one or more attributes. For example, as shown in Figure IC, an object 105a is created with "table" as the type 153, which is based on an indication.
for the rectangle table in the selected attributes 130a in the user input 125a.
Although, in this example, the program code 150a for object 105a. determines "Rectangle" as the option; since no option for the circle table would ultimately provide "Material B" as a 5 selectable option in a subsequent child object (e.g., 115a, 120a). Thus, when determining an appropriate option for type 153 in object 105a, the program code 150a can determine an option that is as good a fit as possible given the initial type, or can simply choose a default option where the user's intent (e.g., "Material B") will never become available in a subsequent child object (e.g., 115a).
10 In addition, as shown in Figure 2, step 240 comprises an act 220--of creating a subsequent object based on the initial option. Act 220 includes creating a subsequent object based on the determined initial option, wherein the determined initial option provides a basis for a subsequent type for the subsequent object. For example, as shown in Figure IC, when the program code 150a of object 105a selects option

15 for "Rectangle", the design software also consults reference library 135, and creates (or reuses) a subsequent child object (i.e., object I IOa), which has a "Type"
161 that is based on the determined option 160.
Step 240 also comprises an act 230 of determining a subsequent option. Act 230 includes determining a subsequent option for the subsequent object based on any of the one or more attributes. For example, object 1 IOa has a type 161 that is based on previously determined option 160 from parent object 105a. In addition, the type 161 for child object 1 I Oa itself has a set 163 of one or more options 165a-b. Program code 150b in object 11 Oa then determines the appropriate option based at least in part on the existing set of valid attributes, such as attributes 130a. If no selected attribute matches an available option, the program code 150b can select a more appropriate (or even a default) option 170a. For example, program code 150b in object I10a selects "Round Legs" since no leg preference is specified in attributes 130a, and neither "Round Legs" nor "Square Legs" have "Material B" or "Color B" as a sub-option.
On the other hand, if the user later enters different user input, such as input 125b, the program code 150b for the corresponding object (e.g., object 113a) might then select or determine an option that is identical to the user's previous indication in attributes 130a. For example, as shown in Figure ID, the user has entered new input 125b that changes the attributes 1.30a to become attributes 130b, having selected a

16 "Circle" option 180 in object 105a (now 105b). In a subsequently created object 113a, the program code 150b then determines "Pentagonal Legs" 185b as the appropriate option, since this option has a possible sub-option that matches "Material B" and/or "Color B".
Accordingly, the schema and methods described herein provide a number of elements for ensuring that a user's intent is captured appropriately, and in a consistent, timely manner.
