Description

Method and device for converting two-dimensional design drawing into three-dimensional design drawing

Technical Field

The present application relates to the field of architectural design, and more particularly, to the automatic conversion of a two-dimensional design drawing generated by software in architectural interior design into a three-dimensional design drawing.

Background

In building interior design, software is generally adopted as a tool to design interiors. After a two-dimensional design is performed in software, it is sometimes necessary to convert the design drawing into a three-dimensional design drawing for easier visual viewing.

The conversion methods available on the market at present basically require assistance with manual intervention, and are converted semi-automatically through software. For example, if there is a short line with unnormal and unknown meaning in some parts, the line must be drawn correctly in software manually and then converted. Due to the above factors, current conversion methods are generally inefficient and also subject to inaccuracies.

In general, in two-dimensional design software, a combination of a plurality of components is briefly expressed by using blocks. For example, a combination of sleeping components that are commonly used in indoor design will be described as an example. The sleeping part combination usually comprises a bed, an air conditioner, a three-hole socket, a five-hole socket, a lamp, a switch and other parts. For accurate conversion, it is necessary to grasp information of coordinates, insertion points, whether or not to mirror images, etc. of the respective parts, and to accurately transfer the information to the three-dimensional design drawing software. However, the conventional conversion method cannot accurately express the above information required for building the three-dimensional design drawing, and thus it is difficult to accurately convert the component combination briefly expressed in the form of a block from the two-dimensional design drawing to the three-dimensional design drawing.

XML is an English abbreviation for extended Markup Language (eXtensible Markup Language). XML files may be used to exchange data. Data can be exchanged between incompatible systems based on XML. The data stored by computer systems and database systems come in many forms and it is time consuming for developers to exchange data between systems across a network. Converting the data into XML format storage will greatly reduce the complexity of exchanging data and also enable the data to be read by different programs. XML data is stored in a plain text format, so that XML is easier to read, record and debug, and data sharing among different systems and different programs is simpler.

In prior art CN111368353A, a method for converting a two-dimensional CAD design drawing into a three-dimensional design drawing is disclosed. The method comprises the following steps: importing a design drawing and splitting the design drawing into a plurality of layers based on preset parameters to obtain layer information; acquiring corresponding component (part) information according to the layer information, setting parent-child nodes for the components based on the component information, and generating a component family list; a model list is generated based on the member family list of each layer, and an example model (three-dimensional design drawing) is generated after the list information is confirmed. In the method, parent-child nodes are adopted to express the component information. However, the prior art still has the technical problems of incapability of automatic conversion, low conversion efficiency, difficulty in accurately expressing the functional modules briefly expressed by the blocks, and the like.

Disclosure of Invention

The present invention has been made in view of the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a method and an apparatus for automatically, accurately, and efficiently converting a two-dimensional design drawing into a three-dimensional design drawing, a storage medium, and an electronic device.

In an aspect of the present application, there is provided a method for converting a two-dimensional design drawing into a three-dimensional design drawing, wherein the two-dimensional design drawing includes parts and modules, and the modules represent unit groups formed by a plurality of parts, the method including:

identifying parts and modules in the two-dimensional design drawing;

describing, namely describing the identified parts and modules by using an intermediate file;

analyzing the intermediate file, and extracting the design information of the parts and the parts contained in the module from the intermediate file;

a calculation step of calculating three-dimensional design information of the parts and the parts included in the module based on the design information of the parts and the parts included in the module extracted from the intermediate file in the analysis step and information in a pre-stored pre-defined file;

a construction step of constructing the three-dimensional design drawing based on the three-dimensional design information of the parts and the parts included in the module calculated in the calculation step.

The scheme has the advantages that the intermediate file and the predefined file are used as carriers, and the three-dimensional design information of each part can be calculated based on the intermediate file and the predefined file, so that the two-dimensional design drawing can be automatically, efficiently and accurately converted into the three-dimensional design drawing.

In another aspect of the application, in the above method, the intermediate file and the predefined file are XML files.

The method has the advantages that the XML file is stored in a plain text format, so that the XML is easier to read, more convenient to record and more convenient to debug, data sharing among different systems and different programs is simpler, and the method is executed among different application programs, different operating systems and even different platforms in a cross-platform XML file mode.

In another aspect of the present application, in the above method, the calculating step includes: and associating the contents in the intermediate file and the predefined file by the ID of the module and the part.

The advantage of this solution is that the ID is used to associate the content of the intermediate file and the predefined file. Generally, the module name or the part name is the contents that can be edited by the user, but the ID is not changed in general, so that even if the user changes the module name or the part name of one of the intermediate file and the predefined file, there is no fear that the intermediate file and the predefined file cannot be associated with each other, thereby improving the editability of the software and providing greater convenience to the user. This is particularly advantageous for cross-application, cross-operating system, cross-platform applications. At the same time, it is also advantageous for the cooperation in the case where the designer of the two-dimensional design drawing is different from the designer of the three-dimensional design drawing. That is, the names of many items need not be identical, but only the IDs need to be identical.

In another aspect of the present application, the method further includes a sorting step of sorting the parts and the parts included in the module according to a predetermined rule after the calculating step, and the constructing step constructs the three-dimensional design drawing according to a sorting order.

The predetermined rule may be any rule, and may be, for example, the importance of a part, such as whether the part is a key part. The scheme has the advantages that the sequence of the module and the parts generated in the three-dimensional design drawing has a certain rule, so that the three-dimensional design drawing generation process is clearer, the three-dimensional design drawing generation process is easy to master by a user, and the management and the modification are easier.

In another aspect of the present application, in the method, the two-dimensional design drawing includes at least one drawing layer, and the identifying step includes: and identifying the module and the part according to the image layer.

The advantage of this scheme lies in, with the help of the picture layer with different modules and part physical isolation to can reduce the probability of misidentification according to different picture layer identification module and part.

In another aspect of the present application, in the above method, the identifying step includes: and determining the basic range of the image layer module or the part based on the image layer name, and identifying the module or the part based on the basic range.

The scheme has the advantages that the basic range of the module or the part in the layer is determined based on the layer name, so that similar elements can be eliminated, and the identification accuracy is further improved. For example, even if the drawing is inaccurate, the double line in the exterior wall layer is not mistakenly recognized as an entrance door because the possibility of being an entrance door has been eliminated. Thus, the identification can be performed without manually performing a software retrace.

In another aspect of the application, in the method, the describing step includes storing information related to the layers in the intermediate file, the parsing step includes extracting layer information of the parts and the parts included in the module from the intermediate file, the parts and the parts included in the module are sorted by layers according to the layer information of the parts and the parts included in the module before the constructing step, and the constructing step includes constructing the three-dimensional design drawing in the sorted order.

The scheme has the advantages that the image layer information is written into the intermediate file from the description step, so that the sequencing according to the image layer information can be considered in the sequencing process, the regularity in the process of constructing the three-dimensional design drawing is further improved, and the user can conveniently master and manage the three-dimensional design drawing.

In another aspect of the present application, in the above method, the constructing step includes: the three-dimensional patterns of the parts and the parts included in the module are expressed using a family stored in advance.

The scheme has the advantages that the three-dimensional patterns of the parts and the parts contained in the module are expressed by using the family, so that three-dimensional modeling is not needed for the parts, the workload is saved, and in addition, the three-dimensional patterns of the parts are neat and attractive, and the visual effect of the three-dimensional design drawing is favorably improved.

Although the method of the present application is not specific to being performed in one or two pieces of software, or to being performed in one or two plug-ins in one piece of software, the method of the present application is particularly well suited to performing one part of the steps in one piece of software and another part of the steps in another piece of software.

In another aspect of the present application, in the above method, the first software is AutoCAD and the second software is Revit.

In the field of interior design, there are many kinds of software for two-dimensional design drawing, and examples thereof include AutoCAD, several CAD software based on secondary development of AutoCAD, CAXA electronic chart, and the like. The method of the present application is not limited to a specific software, but for the convenience of description, the present application takes AutoCAD as an example for illustration.

Similarly, there are many kinds of software for creating a three-dimensional design drawing, and several kinds of software such as AutoCAD and Revit are given. The method of the present application is not limited to a specific software, but for the convenience of description, the present application takes Revit as an example for illustration.

As shown in fig. 3, in a two-dimensional interior layout generated by, for example, AutoCAD, several parts and modules are included. The module is a unit group composed of a plurality of components. Generally, the components may be divided into modules according to home functions. Further, the components may be divided into modules according to the indoor positions. The present application is not limited to the division of the modules.

The entrance door module 1 in fig. 3 may include an entrance door, a door stopper, a door lock, and other components.

The galley module 2 may include a cabinet, sink, cooktop, refrigerator, microwave, etc.

The sleep module 3 may include a bed, an air conditioner, a three-hole socket, a five-hole socket, a lamp, a switch, and the like.

The work module 4 may include a desk, a chair, a computer, a lighting lamp, and the like.

The sanitary module 5 may include components such as a toilet, a shower, a wash stand, and a lighting lamp.

In addition to modules, several individual parts may be included in the two-dimensional design, such as aisle walls 6, dividing walls 7, windows 8, pillars 9, etc. that are not divided into separate parts in any module.

The above parts and modules are only used as examples, and other parts or modules may be included in the indoor design drawing, and other parts or modules may be included in the module.

A method of converting the two-dimensional design drawing of fig. 3 into a three-dimensional design drawing will be described with reference to the flowchart of fig. 4. The following steps may be included in the method of this embodiment.

Step S1, an identification step, which identifies parts and modules in the two-dimensional design drawing.

First, the software or plug-in reads the two-dimensional design drawing. The reading here can be read by a separate software, in addition there are also several existing plug-ins that can perform the identification here. Those skilled in the art will appreciate that there are a variety of software or plug-ins that may be used for identification of modules and parts in two-dimensional design drawings, such as the row room plug-in AutoCAD.

For example, for double lines appearing in a two-dimensional design drawing, it may be identified as a wall, such as a hallway wall 6 or a dividing wall 7.

A sector appearing in a wall area in a two-dimensional plan view can be identified as an entry door module 1 as in fig. 3.

And step S2, describing the step, namely describing the identified parts and modules in an intermediate file.

Intermediate files may be used as carriers for information interaction between different plug-ins or different software of the same software, even between software in different operating systems or platforms.

The intermediate file has various forms, and any data form known to those skilled in the art may be used as long as the interaction of information is realized, and the present invention is not limited in this respect.

The XML file has the superior characteristics of easy reading, convenient recording and debugging, and makes data sharing between different systems and different programs simpler, so the XML file is used as an intermediate file to describe the identified parts and modules in the embodiment.

For example, for a module named "sleep module," the XML file may be as follows:

< fucbody module parameter ═ G-02 ═ SPt ═ 506582.9, -1268394.0,0.0 ═ EPt ═ 508082.9, -1268394.0,0.0 ═ ismorror ═ 0'/>, in sleep module

</Room>

</AutoPlaceModule>

Wherein, < Room roommame ═ C2"> denotes a Room name C2, modulenname ═ sleep module" denotes a module name sleep module, "ModuleIndex ═ G-02" denotes a module ID G-02, SPt ═ 506582.9, -1268394.0,0.0"EPt ═ 508082.9, -1268394.0,0.0" denotes coordinate information of the sleep module, that is, its position in the two-dimensional design drawing, and ismorror ═ 0 "denotes that the module is not a mirror image display.

The coordinate may be represented by a coordinate system of the software itself, or a pixel coordinate or any other manner, which is not limited herein. Of course, the design information may also include many other information such as the rotation angle, which is not described herein again.

The data format of an XML file is well known to those skilled in the art, and therefore, the description of the present application is not described in detail in relation to the way data is stored in an XML file. Therefore, for other data in the sleep module, including various items of information data in the predefined file described later, the application does not describe in detail how the data should be recorded in the XML file, but only exemplifies some data or some items.

Step S3, an analysis step of analyzing the intermediate file and extracting the parts and design information of each part included in the module from the intermediate file.

The intermediate file generated in step S2 is parsed by the software that generates the three-dimensional design drawing or the plug-in thereof. For example, in the case of a sleep module, by reading the content of the XML document, a plurality of pieces of design information such as a room name, a module ID, module coordinates, and whether or not to mirror the image can be obtained.

Those skilled in the art will appreciate that there are many types of software or plug-ins thereof that can be used to generate three-dimensional design drawings, such as the deepening plug-in of Revit, or AutoCAD, etc., and this is not particularly limited. The present application takes Revit as an example for explanation.

Step S4, a calculation step of calculating three-dimensional design information of each component included in the component and the module based on the design information of each component included in the component and the module extracted from the intermediate file in the analysis step and information in a pre-defined file stored in advance.

In Revit, a predefined file is stored in advance. The predefined file stores the design information of the parts and the modules. The design information in the predefined file is different from the design information in the intermediate file, and stores information that is not shown or cannot be expressed in the two-dimensional design drawing, such as parts specifically included in the module, spatial position relationships of the parts, and the like. The predefined file may be, for example, an XML file.

For example, for a sleep module, the predefined information XML file may be represented as follows:

< Module Emamese ═ sleep Module ═ G-02

< FamiliType TypeIndex ═ 0

< FamiliType TypeIndex ═ 1

< FamiliType TypeIndex ═ 2

< FamiliType type index ═ 3 ═ FamiliName ═ five-hole socket ═ TypeName ═ five-hole socket ═ IsKeyFamiliy ═ 0' > < FamiliType >

< FamiliType TypeIndex ═ 4

< FamiliType type index ═ 5 ═ three-jack ═ TypeName ═ three-jack ═ IsKeyFamily ═ 0 >

</FamilyTypes>

……

</KeyFamily>

</Module>

</Modules>

Wherein, ModuleName represents the module name, ModuleIndex represents the module ID, familyName represents the part name in the module, IsKeyFamiliy represents whether it is the key part. Each part contained in the sleep module is defined in the predefined XML file, and specifically comprises an air conditioner, a bed, a lamp, a five-hole socket, a switch and a three-hole socket.

In addition, the position relationship between each part in the module can be written into the predefined information XML file. The predefined locations are, for example, coordinates of the air conditioner with respect to the base point of the sleep pattern (X1, Y1, Z1), coordinates of the lamp with respect to the base point of the sleep pattern (X2, Y2, Z2), coordinates of the three-hole socket with respect to the base point of the sleep pattern (X3, Y3, Z3), coordinates of the switch with respect to the base point of the sleep pattern (X4, Y4, Z4), and coordinates of the five-hole socket with respect to the base point of the sleep pattern (X5, Y5, Z5).

After the position of the base point of the sleep module in the room is obtained, the position (one kind of three-dimensional design information) of each part in the sleep module in the room can be calculated.

For example, in this example, if the coordinates of the sleep module base point from the room base point obtained through the intermediate file are (X0, Y0, Z0), the coordinates of the sleep module components from the room base point may be calculated as follows. For example, the coordinates of the air conditioner from the room base point may be calculated as (X1+ X0, Y1+ Y0, Z1+ Z0), the coordinates of the lamp from the room base point may be calculated as (X2+ X0, Y2+ Y0, Z2+ Z0), the coordinates of the three-hole socket from the room base point may be calculated as (X3+ X0, Y3+ Y0, Z3+ Z0), the coordinates of the switch from the room base point may be calculated as (X4+ X0, Y4+ Y0, Z4+ Z0), and the coordinates of the five-hole socket from the room base point may be calculated as (X5+ X0, Y5+ Y0, Z5+ Z0).

Since the intermediate file describes the design information of the two-dimensional design drawing, the above third-dimensional coordinate Z0 may be 0, and may be omitted in practical applications, but this does not affect the calculation of the coordinates. In addition, since the selection of the coordinate system may be various, the calculation method of the coordinates may be various, and the present application is not particularly limited thereto.

Similarly, the three-dimensional design information of the individual parts may also be calculated based on the information contained in the intermediate file and the predefined file.

Optionally, a sorting step may also be included after the calculating step. That is, the independent parts and the parts in the module are sorted according to a certain rule. For example, the ranking may be according to whether or not it is a key item.

In step S5, a construction step is performed to construct a three-dimensional design drawing based on the three-dimensional design information of the parts and the parts included in the module calculated in the calculation step.

After information such as the name, ID, coordinates, and whether or not each part in the individual part or module is mirrored is acquired in step S4, a three-dimensional design drawing may be constructed based on the information. For example, for a bed in a sleep module, after acquiring the coordinates of the bed, whether it is a mirror image, etc., a three-dimensional pattern representing the bed may be placed at the corresponding location. For the part air conditioner in the sleep module, after acquiring the coordinate of the air conditioner, whether the air conditioner is mirrored or not and other information, a three-dimensional pattern representing the air conditioner can be placed on a corresponding position. Similarly, three-dimensional patterns such as a three-hole socket, a five-hole socket, a lamp, a switch and the like are also placed at corresponding positions, so that a three-dimensional design drawing of the sleep module is finally formed.

Fig. 5 shows a three-dimensional layout of the sleep module after conversion, which includes a bed 31, an air conditioner 32, a three-hole socket 33, a five-hole socket 34, a lamp 35, a switch 36, and the like.

Through the above steps S1-S5, whether the module includes several parts, such as individual parts like a partition wall and a window, or a sleep module, etc., the conversion from the two-dimensional design drawing to the three-dimensional design drawing can be realized by using the intermediate file and the predefined file as a bridge and combining with logical operations. Such conversion is automatic, does not require manual intervention, and is highly accurate.

The content in the intermediate file and the predefined file need to be associated in some way. As an example, association may be by a module ID. For example, in the data of the intermediate file sleep module exemplified above, the ID of the sleep module is G-02. In the predefined file, the ID of the sleep module is also G-02, so the intermediate file is associated with the same module in the predefined file by the same ID. Of course, the association method is not limited, and for example, a module name may be used for association, but when the module name is long, it is not convenient to use the module name for association, and thus it is preferable to use ID association. In addition, if the module name is editable, it is more convenient from the user's perspective. In view of this, it is appropriate to adopt a variable that is not edited as an associated variable.

The layer is a useful tool in two-dimensional design software. By distinguishing the layers, various elements such as different modules or independent parts in the indoor design can be drawn on different layers. In the construction process, professional construction teams can distinguish symbols, line segment forms and colors of the drawing according to related design drawings of respective professional fields, and have different industry specifications. Meanwhile, the distinction of the layers is also greatly convenient for the modification of a design process or a construction process after a certain link has a problem, the normal operation of other steps is not influenced, simultaneously, the working efficiency of a designer team is greatly improved, and because everyone can be responsible for the good part and distinguish the layers, the drawing which is finally gathered together is also accurate.

In this application, the two-dimensional design preferably has at least one layer. For example, a passageway wall 6, a dividing wall 7, or the like may be provided to the exterior wall pattern layer. The sleep module 2 may be arranged to the sleep module layer. The sanitary modules 5 may be arranged to the sanitary module layer.

In the case of a two-dimensional design having at least one layer, the method for converting a two-dimensional design into a three-dimensional design according to another embodiment may be performed as shown in fig. 6.

And step S11, an identification step, namely identifying the parts and the modules in the two-dimensional design drawing according to the drawing layer.

The following steps S111 to S114 may be included in step S11.

As shown in fig. 7, first, in step S111, the first layer is read and recognized. For example, in the case where the first layer is an exterior wall layer, the double line is identified as a wall.

In step S112, the second layer is read in and identified. For example, in the case where the second layer is a sleep module layer, the block diagram of the bed pattern is identified as a sleep module.

In step S113, the third layer is read in and recognized. For example, in the case where the third layer is a sanitary module, the block diagram with the toilet, shower, etc. is identified as the sanitary module.

In step S114, the nth layer is read and recognized.

Further preferably, a basic range of the layer module or the part is determined based on the layer name, and the module or the part is identified based on the basic range.

As shown in fig. 8, in the recognition step S11, steps S115 to S117 may be included.

Specifically, in step S115, the layer name, for example, "exterior wall layer" is read.

In step S116, the basic range of the layer module or the component is determined according to the layer name. For example, when the layer name is "exterior wall layer", it is determined that the basic range of the module or component in the layer is an exterior wall, and the module or component does not include a sleep module or a bathroom module.

In step S117, the module or component is identified based on the basic range of the module or component in the layer. For example, when the basic range of a module or part in a layer is an outer wall, a double line is recognized as an outer wall, and is not recognized as an entrance door.

This preferred embodiment has the advantage that even if there is a case where the drawn line is inaccurate and easily misrecognized, since the basic range has already been determined by the layer name, the probability of misrecognition can be reduced. Therefore, manual intervention can be reduced, automatic conversion is realized, and conversion with high accuracy is realized.

The description continues with reference to fig. 6.

Step S12, in describing step S2, includes storing information related to the layers in an intermediate file.

Information related to the layer, such as a name of the layer, a creation time of the layer, a creator of the layer, a modification time of the layer, a modifier of the layer, and the like, may be stored in the intermediate file.

In step S13, the analyzing step S3 includes extracting parts and layer information of each part included in the module from the intermediate file.

In this step, the information extracted from the intermediate file by the three-dimensional design drawing software or the plug-in includes the image layer information of the parts and the parts in the module. The information comprises the name of the layer, the establishment time of the layer, the establishment person of the layer, the modification time of the layer, the modification person of the layer and the like.

Step S14, optionally, sorting the parts and the parts in the module according to the layers. The rules herein may be, for example, ordered by layer name, ordered by creation time of the layer, ordered by modification time of the layer, ordered by creator, ordered by modifier, and so on.

Step S15, the constructing step S5, includes constructing the three-dimensional design drawing according to the order.

The method has the advantages that the process of generating the three-dimensional design drawing is carried out according to the layers, so that the process of generating the three-dimensional design drawing is clearer and is easier to manage and modify.

Additionally, in three-dimensional design drawing software or plug-ins, family is a common tool. For example, the Revit family is a class of primitives in a class, and groups primitives according to a common set of parameters (attributes), the same in use, and the similarity of the graphical representation. Some or all of the attributes for different primitives in a family may have different values, but the settings of the attributes are the same. When Revit is used for project design, if a large number of family files are owned in advance, great help is brought to the design work progress and benefit. The designer does not need to spend additional time on making the family file and endowing the parameters with the family file, but directly imports the corresponding family file and can directly apply the family file to the project. In addition, the use of the Revit family file allows designers to focus on exploiting their own specialties. Such as indoor designers, do not need to expend much effort on the three-dimensional modeling of furniture, but focus on the design itself by directly importing the rich library of indoor furniture families in the Revit family. Each family primitive can define multiple types within it, each type can have different size, shape, material setting or other parameter variables, depending on the design of the family creator, and various parameters can be added to the family as desired by the user, such as distance, material, visibility, etc. In addition, real-life building components and graphical/annotation components can also be created using family editors.

In a preferred embodiment of the present application, the three-dimensional patterns of the components and the components included in the module are preferably expressed using a family diagram of Revit. In this case, through directly being suitable for the family of Revit, need not carry out three-dimensional modeling for the part to save work load, the three-dimensional pattern of each part is neat pleasing to the eye in addition, is favorable to promoting the visual effect of three-dimensional design drawing.

It should be noted that the present application has been described taking an architectural interior design as an example, but those skilled in the art will understand that the method of the present application is not limited to the architectural interior design field, but can be applied to conversion from a two-dimensional design drawing to a three-dimensional design drawing in various fields.
