In CAD system, user may want to model the design of object, generate the manufacture for manufacturing the object Instruction, or modify to design or fabrication order.Can object or article be represented as include machine part, vehicle, That equips the solid including installation, building layout, engineering structure or chemical structure uses Direct Modeling or change in any case Point Direct Modeling, but the present invention is not restricted to these application.Threedimensional model allows to export the quality or weight of component, and can be true Fixed and the other assemblies in other systems interactions.The disclosure applies also for other kinds of model, such as parametric modeling, base It is modeled in the modeling of feature or history.

For the purpose of the embodiment of description method and system, following meanings are applicable in and pass through the example of Fig. 8 a to Fig. 8 d Carry out further progress diagram.Term " rounding body " includes the face generated and being rounded edge." rounding chain " includes by making The edge of one group of connection is rounded and the rounded surface of one group of connection that is formed, for example, the shadow surface 27 such as Fig. 8 a is illustrated, in this way One group of connection rounded surface formed rounding chain." rounding substrate " refers to already present before creating rounding body and is rounding The entity being based on.These had usually previously intersected to form the adjacent surface on edge or vertex." relying on rounding body " refers to: if The face is mobile, then existing must be by the rounded surface of " rounding again ", for example, as illustrated in Fig. 8 b, along the direction of arrow 29 Mobile face 28 needs opposite 30 to carry out rounding again.Relying on rounding body always includes the rounded surface that mobile face is substrate, but can also To include other faces." rounding again ", which refers to the process of, regenerates rounding body.When model has changed, it is based on rounding body The substrate having changed regenerate rounding body, allowing rounding body to be based on, ongoing editor is mobile or change shape.When two When a rounding body is each another substrate, such two rounding bodies are " complementary ", for example, such as institute in Fig. 8 c Show, two shade roundings body 31,32 therein is complementary.Based on a series of dependence of complementary rounding bodies, A series of this complementary rounding body forms complementary rounding band.In the example of Fig. 8 d, shadow surface 33,34,35 It is an example of the band that length is three.

Assuming that typical model includes connecting element, wherein rounding body provides completion details, such as shown in fig. 3a, Middle feature 11,12 is connected and is completed by rounding body 13.The expression of Fig. 3 a includes flat shape face 19 and cylinder face 20.When via being based on The operation of selection is come when editing 3D or 2D model, movement such as on the assigned direction that arrow 17 indicates, for selected entity, User's expected behavior of the standard of system is to move together.Entity may include the face 18 or rounding body (rounding for 3D model Face) edge in 13 or 2D model or curve and rounded edges or rounding curve (not shown).This is generally interpreted as making Selected face or edge keep rigidity, it is meant that such face or the identical transformation of marginal reception.About being related to face and rounding The 3D model of body describes example, but this method is equally applicable to the 2D model with edge and rounded edges.

Common selection technique in CAD system is referred to as " rubber belt " or " fence " selection.Such situation is: in screen Upper drafting shape, usually rectangle, and all entities in the shape are all added in selection.This is usually used to selection The entire side or end of all entities or component in one feature, so as to the mobile side or end.Fig. 2 diagram Typical rubber belt selection is gone out, wherein some faces 14 in 3D model and rounding body 15 or edge and rounding in 2D model Edge (not shown) is fallen into selected shape 16.Using the technology, user is easy to that excessive face can be selected, including some does not have Intend the rounded surface rigidly moved with the rest part of selection.Especially in large-scale model, this can be in user even without note It anticipates in the case where and occurs, so that it is unrealistic and unreasonable that cancellation, which selects these entities,.Excessively selection typically results in shifting Dynamic failure or edit action are bad.

Using example shown in Fig. 3 a, this behavioral problem can be illustrated.Fig. 3 a is archetype, on archetype The characteristics of can be selected, such as selected by user or by system command.In this example, protrusion 12 is located at indicated sense In interest region, and attempt to move along the direction of arrow 17.Other modelling operabilities symbol, such as rotate, be sized, deviating, Come to a point, replace etc., it can be applied in disclosed method, but for convenience's sake, be operated about " movement " to describe The example of this paper.Selected face 13,18 in area-of-interest includes the rounded surface 13 of the base portion around feature 12.Fig. 3 b shows Go out based on how the criterion behavior for moving all selected faces 13,18 along the direction of arrow 17 leads to incorrect result. Since selected face includes rounding body 13, the face 20 (being in this example base portion 11) of this feature for forcing protrusion to be connected to It is moved with selection, so as to keep tangent, in this illustration since the bottom geometry in face 20 is cylinder, so This face 20 is cylinder face or cylinder.Face 19 is plane or flat shape face, and the mobile direction that hesitates in this example is in this plane It is interior, so the plane will not move.For different moving directions, plane 19 can also be forced mobile.Desired result is such as Illustrated in Fig. 3 c.It is desired the result is that: for characteristic face 18, rigidly to move, but for rounding body 13, to make such The location and shape of rounding body adapt to their surrounding face, rather than force their surrounding face 19,20 mobile.

Another example is illustrated in figs. 4 a and 4b.Fig. 4 a is shown with face 18 and rounding body 13, flat shape face 19 With the archetype in cylinder face 20.It is instructed in a manner of identical with the example of above-mentioned Fig. 3 a, such as by user or by automatic system Feature 12 is selected, and attempts to move along the direction of arrow 17.Cylinder face 20 is immovable at this time.It such as can from Fig. 4 b Out, cylinder face is fixed, but attempts to move along the direction of arrow 17 and will lead to operation failure, because of rounded surface 13 and cylinder Tangent needs between 20 are disconnected.

The present disclosure describes a kind of methods, for determining which rounding body should be rigid in selection, to edit Behavior is improved when model.In one embodiment, it provides a method, for analyzing selected entity, and determines and exist Which rounding body in selection should keep rigidity and which rounding body should be adapted to simply.However, not in specific selection Interior all rounding bodies can be abandoned simply from selection.In the example of Fig. 5 a and Fig. 5 b, multiple 21,24,25 quilts of face Selection is for moving.Selected face 21,24,25 includes the rounding body that cannot be dropped, therefore from the selection in Fig. 5 a The result for abandoning rounding body will is that user will not obtain any of selection in response to moving along the direction of arrow 22 and instruction It is mobile.From the selection of Fig. 5 b abandon rounding body the result is that: the face 25 of Fig. 5 b will be moved along the direction of arrow 26, but result will It is undesirable.

Fig. 6 a totally shows disclosed method.This method includes being executed on a data processing system with edit model The step of, these steps include: for example to be received interested in the expression generated by model by selecting 80 interested regions The instruction in region.It is 3D or 2D according to model, which includes one or more entities, face or edge.It determines to be applied To the editor of selected area-of-interest.Test 81 is by for the selected area-of-interest there are rounding entity All entities are constituted, and in this process, and all non-rounding entities are assigned 82 and arrive editor group.Editor group can also be by Referred to as retain (KEEP) list, because the group includes the entity for the entity and editor to be applied to be retained.It will find Rounding entity distribution 83 to test group, and to test group in all rounding entities carry out test 84 with determine those Whether rounding entity includes boundary rounding entity.Boundary rounding entity can also be referred to as and ignore (IGNORE) group 85, because Editor will not be applied to those entities.It is not that the rounding entity of boundary rounding body can be added 86 to editor group.So Editor is applied into 87 all entities into editor group afterwards, and then by boundary rounding entity again rounding 88 to having edited Physically.Then the expression for the area-of-interest edited can be exported to 89 for example to storage device or display, edited Area-of-interest expression include edit substance and again the boundary rounding entity of rounding.

Fig. 6 b shows the more detailed embodiment of the disclosed method for 3D model.Described method will be various Difficulty is taken into account and is determined which rounding body can be abandoned using some heuristicses, to provide behavior improvement, simultaneously Those required to holding rounding body.For all entities in selection, assorting process shown in Fig. 6 b can be followed.Fig. 6 b and It is described below and entity is known as face, but as indicated above, this method can be equally applied to side or song in 2D model Line, and unless otherwise stated, the side or curve replacement face in 2D model can be used.The process considers each face, determines It is to maintain or ignores this face.Retaining surface will become change rigid and that these faces are exported from the operation being carrying out It changes.Based on the new position for ignoring the retaining surface that face is relied on, such face of ignoring is by rounding again.

In first step, select face 40, then carry out checking that 41 with the above-mentioned face of determination be rounding body 42, also whether rounding Body 43.Therefore, which is divided into rounding body and non-rounding body for selected face.For 2D example, by selected edge It is divided into rounding body and non-rounding body.Non- rounding body will be to maintain face 44 always.The face for being confirmed as rounding body is all undergone A series of initial testings 45 are to check the following contents.At least one has that substrate is unselected, and at least one substrate is selected It selects, and rounding body is dependent at least one face in the list of retaining surface 44.This is checked for ensure then will correctly Rounding again is carried out to rounding body is ignored, this is a part of the update of model.It is any not pass through the rounding body quilt of these inspections It is classified as retaining surface 44.Then it checks through the rounding bodies of 47 initial testings 45 to determine that they are to rely on rounding body or mutual The rounding body of dependence.

In this stage, all remaining rounded surfaces all rely on the face kept in list 44 now.Then these roundings Face is divided into two classes, that is, complementary rounding body 48 and dependence rounding body 49, because of the analysis to these two types of rounded surfaces It is different.For complementary rounding body, the rounding body of any non-selected end in a band can only be ignored.This is logical It crosses and executes complementary rounding body test 50 and completed with checking the following contents.Rounding body chain is greater than length 1, this is in order to true Guarantor face is actually a rounding body, rather than just the face that can be identified as rounding body, and the total length of band is greater than 2, and the number of selected substrate is one, and selected substrate is the rounding body in the same band.By 52 these Any face checked is all placed in the list for ignoring face 53, is not all placed in and is kept in list 44 by 54 any face.

By checking 51 the following contents repeatedly, remaining relies on rounding body 49 and is classified as ignore or keep.If all The substrate of rounding body then keeps 55 rounding bodies all in current holding list 44；If rounding body is cylinder, and its chain Length is 1, and it depends on its rounding body without other, then keeps 55 rounding bodies；If rounding body is cylinder, and rounding The chain of body a length of one, and the dependence object of rounding body --- i.e. dependent on those of this rounding body rounding body --- are all solutions Analysis type, i.e. one in cylinder, sphere or anchor ring, then keeping 55 this rounding body；Otherwise, ignore 56 this rounding body. This process is repeated, keeps list 44 until being added to there is no rounding body.The step of this paragraph is for the exemplary spy of 3D Different situation, these steps are not applicable when using 2D model.

From step outlined above, generates the list 44 of retaining surface and ignore the list 53 in face.Then, it would be desirable to volume (for example, movement for selected entity in given directions) is collected to be applied to from the holding determined in face those of in selection Face, and be not applied to ignore face from what is determined in face those of in selection.After editor is applied to retaining surface, by base Rounding again is carried out to the rounding body in the list for ignoring face in the new position for the retaining surface that they are relied on.

Fig. 7 a to Fig. 7 d shows some specific examples how disclosed method is applied.For example, in Fig. 7 a The selection of face and rounding body will comply with the process of Fig. 6 a or Fig. 6 b to generate retaining surface 60 and ignore face 61.It then can be along arrow Retaining surface is moved with executive editor in 63 direction, and based on the new position for ignoring the retaining surface 60 that face 61 is relied on, such Ignore face 61 by rounding again.For Fig. 7 b, which generates retaining surface 64 and ignores face 65.It is then possible to along arrow 66 Retaining surface 64 is moved in direction, to execute desired editor, and based on the new position for ignoring the retaining surface 64 that face 65 is relied on, Such face 65 of ignoring is by rounding again.In the example of Fig. 7 c, there are multiple retaining surfaces 67 generated by the process and more It is a to ignore face 68.Then retaining surface 67 can be moved along the direction of arrow 69 to execute desired editor, and is based on ignoring Face 68 is ignored by rounding again in the new position for the retaining surface 67 that face 68 is relied on.Show finally, Fig. 7 d illustrates following one Example: this process generates multiple retaining surface 70a, 70b, 70c.Retaining surface 70a and 70b is adjacent, but retaining surface 70c is by ignoring face 71 and separated with retaining surface 70b.Therefore, even for discrete retaining surface, desired editor can also be by application along arrow The movement in first 72 direction, subsequently, based on the new position for ignoring the retaining surface 67 that face 71 is relied on, such face 71 of ignoring is by again Rounding.

A variety of advantages include but is not limited to obtain the expected result for being used for edit model, and time-consuming point is carried out without user Analysis and interaction.Disclosed method and system allow the variational systems based on selection to change the choosing that user has made automatically It selects, to carry out the anticipated movement of selected entity.It is more easily and more intuitive that this causes system to use, the effort and skill to user The requirement of energy is lower.In the sense that more editing successfully, which is more reliable, and system response is faster, because The model that variation solves is fewer and fewer.It under some cases for being related to many rounding bodies, is selected via rubber belt, the side of the disclosure Method supports the practical desired editor of realization.The method discussed is supported to abandon rounding body from selection, desired straight to provide Sight behavior, and be adapted to allow for carrying out 2D or 3D model any CAD system of selection driving editor.
