Description

An intelligent linkage update method for 3D design reinforcement drawings that supports multiple modes

Technical field

The invention relates to the technical field of reinforcing bar drawing updating, and specifically relates to an intelligent linkage updating method for three-dimensional design reinforcing bar drawings that supports multiple modes.

Background technique

Reinforcement drawings are one of the main output results of the civil engineering structural design industry, including structural lines, reinforcement point lines and reinforcement markings.

In the process of drawing three-dimensional reinforcement drawings, structural lines and steel bar point lines can be calculated directly through sectioning or projection, and steel bar labeling is calculated and generated by a special labeling algorithm. Although the existing steel bar labeling algorithms have basically achieved automatic generation of steel bar labels with regular structures and less interference, manual adjustment of steel bar labels is still unavoidable when the model structure is complex. At the same time, three-dimensional design, especially three-dimensional reinforcement design, is an iterative process, and the model usually needs to be modified repeatedly, which involves the linked update of existing reinforcement drawings. Updates of structural lines and reinforcement point lines can be calculated and replaced directly from the 3D model. Reinforcement labeling requires comprehensive consideration of model changes and is usually manually adjusted, so its update is more complicated.

"Application of 3D Reinforcement Drawing Technology in Hydropower Engineering" The RebarSmart 3D rebar digital design system developed based on CATIA directly refreshes the rebar drawing and redraws the rebar labeling after the three-dimensional rebar model changes. Although the rebar drawing is updated, However, all adjustments made by the user to the steel bar markings are roughly discarded, which increases the user's workload of repeatedly adjusting the steel bar markings.

ReStation introduced in "Introduction to Rebar Drawing Technology of ReStation System" will record the steel bar labeling adjusted by the user and retain the corresponding labeling style in the updated steel bar drawing. Although this solution reduces the user's workload of repeatedly adjusting the steel bar labeling, there are When the steel bar model is changed, the annotations cannot be refreshed in conjunction, causing the steel bar diagram information to be disconnected from the three-dimensional reinforcement model. In addition, the above two reinforcement diagram update methods only provide fixed update modes, which are difficult to meet the actual application needs of users.

To sum up, the existing 3D design reinforcement diagram update method has the problems of simple and blunt method, single mode and redundant calculation. It is necessary to develop a method that can provide multiple update modes for different usage scenarios and the update results comprehensively consider model changes and label adjustments. An intelligent linkage update method for three-dimensional design reinforcement drawings based on model selection is very necessary.

Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clear, this application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

As shown in Figure 1, this embodiment provides an intelligent linkage update method for three-dimensional design reinforcement drawings that supports multiple modes, including:

S1. Obtain the information of the source reinforcement diagram and the update mode m of the reinforcement diagram, and regenerate the target reinforcement diagram on the three-dimensional reinforcement model based on the corresponding section plane or projection plane of the source reinforcement diagram; among them, the update mode includes the linkage update mode and visual update mode and global update mode. In this embodiment, m=0 indicates that the update mode is linkage update mode, m=1 indicates that the update mode is visual update mode, m=2 indicates that the update mode is global update mode; source steel bar The information of the drawing includes: structural line, steel bar group, steel bar label, scaling ratio, section plane or projection plane identification. The information of the target steel bar diagram includes: structural line, steel bar group, steel bar label, scaling ratio, section plane or projection plane identification.

The data organization structure and meaning of the reinforcement diagram are shown in Figure 2. Among them, the steel bar group identifier is the unique identifier of the three-dimensional steel bar group. The three-dimensional steel bar group, the steel bar group in the steel bar diagram, and the steel bar label are all related through the steel bar group identifier. Therefore, for the three-dimensional steel bar group, the steel bar group in the steel bar diagram, and the steel bars of the steel bar group The annotations have the same rebar group ID, and the rebar group ID of the 3D rebar group once generated will not change unless it is deleted and re-added, that is, if the 3D rebar group in the 3D reinforcement model is modified, The three-dimensional steel bar group, the steel bar group in the steel bar diagram, and the steel bar group identification of the corresponding steel bar label will not change.

It should be noted that the data source for updating the reinforcement diagram is the existing reinforcement diagram and the three-dimensional reinforcement model. Among them, the existing steel bar diagram records the steel bar labeling data adjusted by the user, and the three-dimensional reinforcement model provides the latest structural line and steel bar group data. Define the existing reinforcement diagram selected by the user as the source reinforcement diagram, and the newly generated reinforcement diagram of the three-dimensional reinforcement model as the target reinforcement diagram. The reinforcement diagram updates supported by this method include: modification of the 3D model structure, addition of the 3D reinforcement group, modification of the 3D reinforcement group, and deletion of the 3D reinforcement group.

The source reinforcement diagram data that this method retains as much as possible includes: reinforcement label modification and reinforcement label deletion. Since users have different reinforcement diagram update requirements in different scenarios, this method provides three reinforcement diagram update modes for users to choose from. Among them, the linked update mode only updates the reinforcement labels corresponding to new, modified and deleted three-dimensional reinforcement groups. The annotation retains the style in the existing reinforcement drawing; the visual update mode, based on the linked update mode, also updates all the rebar annotations retained on the source rebar drawing, that is, except for the rebar annotations deleted by the user and the corresponding three-dimensional rebar group has not been modified, the rest All are updated; the global update mode generates a new steel bar diagram based on the three-dimensional reinforcement model, and all the steel bar annotations in the picture are regenerated.

S2. Compare the scaling ratio and structural lines of the source reinforcement diagram and the target reinforcement diagram. If the scaling ratio or structural lines are inconsistent, modify the update mode m to the global update mode; step S2 specifically includes:

S21. Determine whether the scaling ratios of the source reinforcement diagram and the target reinforcement diagram are equal. If not, modify the update mode m to the global update mode and execute step S3; if yes, execute step S22;

S22. Obtain the shape combination SS corresponding to the structural line of the source reinforcement drawing and the shape combination SS corresponding to the structural line of the target reinforcement ^drawing . If the number of basic shapes of SS ^- is not equal to the number of basic shapes of SS, modify the update mode m to global. Update mode, execute step S3; otherwise, execute step S23;

As shown in Figure 4, the basic shape includes a straight line segment, an arc and a spline. The parameters of the straight line segment include the coordinates of the two endpoints. The parameters of the arc include the center coordinates, rotation angle, starting angle, ending angle, long radius, and short radius. , the parameters of the spline are the coordinates of the control points; any structural line can be composed of basic shapes.

S23. Traverse the shape combination SS ^- and determine whether the shape combination SS ^- is consistent with the shape combination SS. If they are inconsistent, modify the update mode m to the global update mode and execute step S3.

It should be noted that although this method provides three update modes for users to choose from, the global update mode will be forced when the following two situations exist: 1. The target reinforcement diagram adopts a scaling ratio different from the source reinforcement diagram; 2. The target reinforcement diagram The structural lines of the drawing differ from the source reinforcement drawing. When the target reinforcement drawing adopts a scaling ratio different from that of the source reinforcement drawing, the reinforcement markings in the source reinforcement drawing will be offset from the reinforcements and structures in the target reinforcement drawing, as shown in (b) in Figure 3, so the reinforcement markings need to be completely re- calculate. When the structural lines of the new steel bar drawing are different from the source steel bar drawing, the properly laid out steel bar annotations on the source steel bar drawing may break away from the corresponding steel bar group or interfere with the structural lines of the new steel bar drawing, as shown in (c) in Figure 3 shown, therefore all rebar dimensions need to be recalculated based on the new structural lines and rebar point lines.

S3. Determine whether the update mode m is the global update mode. If so, execute step S7; otherwise, execute step S4;

When the update mode m is the global update mode, all reinforcement groups in the target reinforcement diagram will recalculate the labels, and all the reinforcement labels in the source reinforcement diagram will not be retained in the target reinforcement diagram, so you can jump directly to the last step S7 to update the target Just mark the steel bars on the steel bar diagram.

S4. Traverse each steel bar group T _j in the source steel bar diagram. If a certain steel bar group T _j in the source steel bar diagram exists in the target steel bar diagram, add the steel bar label B _j corresponding to the steel bar group T _j to the target steel bar. Figure: Determine whether the update mode m is a linkage update mode. If so, execute step S6; otherwise, execute step S5;

Step S4 specifically includes:

S41. Traverse each steel bar group T _j in the source steel bar diagram, and obtain the steel bar label B _j and steel bar group identifier RI _j corresponding to the current steel bar group T _j ;

S42. Retrieve the steel bar group with the steel bar group ID RI _j in the target steel bar diagram. If there is a steel bar group ID RI _j for the steel bar group R _i , then use the steel bar label B _j as the steel bar label of the steel bar group R _i .

When the update mode m is non-global update, some of the reinforcement annotations of the source reinforcement diagram will be retained in the target reinforcement diagram. The reinforcement label retention strategy is: first copy the reinforcement labels in the source reinforcement diagram to the target reinforcement diagram, and then delete the labels that need to be updated from the target reinforcement diagram through filtering. Since some 3D reinforcement groups may have been deleted in the 3D reinforcement model, during the process of copying the reinforcement labels in the source reinforcement diagram to the target reinforcement diagram, the reinforcement labels corresponding to the deleted reinforcement groups need to be deleted.

It should be noted that in step S4, the reinforcement label with the hidden mark h as Yes is also copied to the target reinforcement diagram.

S5. Traverse each steel bar label in the target steel bar diagram. If the hidden identifier h of the current steel bar label A _i is No, delete the steel bar label A _i ;

It should be noted that the hidden mark h corresponding to the steel bar label "deleted" by the user in the source steel bar diagram is yes, and the rest is no. The hidden flag h is yes, which means that the steel bar label actually exists, but is visually deleted through hiding. That is to say, the user has deleted a certain steel bar label in the source steel bar diagram, but in fact the steel bar label actually exists. The steel bar label has not been deleted, but the delete command has been replaced by a hidden command. If the hidden flag h is No, it means that the steel bar label is copied directly from the source steel bar drawing to the target steel bar drawing.

The purpose of using the hidden identifier h is to prevent the deleted reinforcement labels from being recalculated and generated during the reinforcement diagram update process. For example, the user deletes the steel bar label B _j corresponding to the steel bar group T _j in the source steel bar diagram. If the information of the steel bar label B _j is completely deleted, then the A _i corresponding to B _j in the target steel bar diagram does not exist, step S7 The rebar label A _i will be regenerated for the rebar group R _i . By assigning the hidden flag to "Yes" to hide the "deleted" reinforcement labels, you can avoid the "deleted" reinforcement labels in the source reinforcement diagram from being regenerated after the reinforcement diagram is updated. When the update mode is the visual update mode, all undeleted rebar annotations in the source rebar diagram need to be updated, so all rebar annotations copied to the target rebar diagram with a hidden mark of "No" need to be deleted, so that in step S7 Re-generate rebar annotations for visual updates.

S6. Traverse each steel bar group R _i in the target steel bar diagram. If the geometry of the current steel bar group R _i is inconsistent with the corresponding steel bar group T _j in the source steel bar diagram, delete the steel bar label A _i corresponding to the steel bar group R _i ;. Step S6 specifically includes:

S61. Traverse each steel bar group R _i in the target steel bar diagram, and retrieve the steel bar group T _j in the source steel bar diagram that has the same steel bar group ID as the steel bar group R _i ; if the steel bar group T _j does not exist, traverse to the steel bar group R. _i+1 ;

S62. Determine whether the geometry of the steel bar group R _i and the steel bar group T _j are consistent. If they are inconsistent, delete the steel bar label A _i corresponding to the steel bar group R _i . The method for judging whether the geometry of the steel bar group R _i and the steel bar group Tj is consistent includes: As shown in Figure 6, the geometry of the steel bar group is represented by a set of shape combinations. Each steel bar is represented by a shape combination, and each shape combination is represented by Composed of one or more basic shapes. Determine whether the rebar group R _i and the rebar group T _j are geometrically consistent, that is, determine whether the parameters of each basic shape in the shape combination corresponding to the rebar group R _i are the same as the parameters of each basic shape in the shape combination corresponding to the rebar group T _j . Completely consistent, if there is inconsistency, the steel bar group R _i is geometrically inconsistent with the steel bar group T _j .

After the three-dimensional steel bar group is modified, its steel bar labeling in the target steel bar diagram needs to be updated simultaneously. Modification of the three-dimensional steel bar group includes geometric modification and attribute modification, as shown in Figure 5. The geometric modification is the modification of the number, shape and position of the steel wires, and the attribute modification is the modification of the diameter and grade of the steel bars. For attribute modification, the steel bar label only needs to replace the text content without recalculation, as shown in (b) in Figure 5; for the geometric modification of the three-dimensional steel bar group, only when its sectioning or projection in the steel bar diagram occurs If there is a change, the reinforcement labeling needs to be recalculated, as shown in (c) in Figure 5. This method determines whether the corresponding steel bar labels in the target steel bar group need to be deleted for updating in step S7 by comparing whether the corresponding steel bar group geometry in the target steel bar diagram and the source steel bar diagram are consistent.

S7. Traverse each steel bar group _Ri in the target steel bar diagram, update the label text of the steel bar label corresponding to each steel bar group _Ri , or label each steel bar group _Ri . Step S7 specifically includes:

S71. Traverse each steel bar group R _i in the target steel bar diagram, and retrieve the steel bar label A _i in the target steel bar diagram that is consistent with the steel bar group ID of the current steel bar group R _i . If A _i exists, based on the current steel bar group R _i The attribute information updates the label text of steel bar label A _i ; if A _i does not exist, execute step S72;

S72. Call the steel bar labeling algorithm to label the current steel bar group R _i , and obtain the steel bar label A ^* _i ;

S73. Set the steel bar group ID of the steel bar label A ^* _i to the steel bar group label of the current steel bar group R _i , and add the steel bar label A ^* _i to the target steel bar diagram.

The following will explain in detail how this method can simultaneously update the steel bar labels by adding, modifying and deleting the steel bar groups in the three-dimensional reinforcement model while retaining the steel bar label styles and deletion records in the source steel bar diagram as much as possible (in the linked update mode).

When a new steel bar group is added to the three-dimensional reinforcement model, if the new three-dimensional steel bar group is projected or cut into the target steel bar drawing to form a two-dimensional steel bar group R _i , since the steel bar group R _i does not have a corresponding steel bar label in the source steel bar drawing, Therefore, the added reinforcement label will be calculated in step S72;

When the steel bar group in the three-dimensional reinforcement model is modified, if only the attributes are modified, the linkage update can be completed by simply updating the annotation text in step S71. If the geometry modification causes the corresponding geometry of the steel bar group R _i in the target steel bar diagram to occur changes, step S6 will delete the steel bar label A _i corresponding to the steel bar group R _i and recalculate the steel bar label A i through step S72;

When the three-dimensional steel bar group is deleted, step S4 will not add its corresponding steel bar label B _j in the source steel bar diagram to the target steel bar diagram.

When the user deletes the steel bar label B _j corresponding to the steel bar group T _j in the source steel bar diagram, the hidden flag h of the steel bar label B _j is set to Yes, and is copied to the target steel bar diagram to form the steel bar label A _i . The steel bar label A _i will always be retained. But it is not displayed, thereby avoiding step S72 to calculate the steel bar label A _i again. All rebar annotations in the source rebar drawing other than the above scenarios will be copied to the target rebar drawing through step S4 and retained until the end of the method.

The only difference between the visual update mode and the linked update mode is that in step S5, all the steel bar annotations A _i whose hidden identifier h is negative are deleted, so that in step S7, all the steel bar annotations deleted in step S5 can be recalculated.

The above-described embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still implement the above-mentioned implementations. The technical solutions described in the examples are modified, or some of the technical features are equivalently replaced; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions in the embodiments of this application, and should be included in within the protection scope of this application.
