Problems solved by technology

[0005] At present, non-standard design has two-dimensional design in AutoCAD, which is a traditional design method, and the design efficiency is low; the other is three-dimensional design in three-dimensional modeling software, such as stretching, sweeping, and lofting. The design method still requires the designer to design one stroke at a time, and the design efficiency needs to be improved.
[0006] In view of this, the current improved method is to first design the three-dimensional non-standard parts and parameterize them, then change the parameters of the parts according to the non-standard dimensions to be designed and splice them together. First of all, this method is not designed in the environment of the workshop model project. Effectively avoid other equipment and structural beams, columns, etc.; after the non-standard design is completed, it must be re-arranged in the workshop model, and it is a mechanically complicated work to locate the non-standard during the layout; Non-standard size to adjust the position of the equipment, in this case, this method also has a lot of inconvenience
Furthermore, this method still requires many manual steps, the degree of computational design is not high, and the computational simulation ability of the computer is not fully utilized. This has a certain relationship with the development tools and development environment used. For example, using the traditional Revit API for secondary development requires Good programming foundation, long development time, high threshold and other shortcomings

Embodiment 1

[0037] In this embodiment, a method of using Dynamo to realize the rapid modeling of non-standard parts in the BIM design of cement plants is provided. This method can be used to design and draw three-dimensional models of non-standard parts for conveying solid materials and gases in cement plants. At the same time, this method can also be used to draw a three-dimensional model similar to a pipeline with known size and position of both end faces and a known direction, such as figure 2 As shown, the method includes:

[0038] (1) if figure 1 As shown in , move the rotation center of the 3D view to the vicinity of the position where the non-standard part is to be built, that is, the adjacent upstream model and downstream model in the process flow. The upstream model and downstream model refer to upstream equipment and downstream equipment .

[0039] (2) Based on the Dynamo plug-in of Revit software, run Dynamo, establish the connection of each function and carry out visual pro...

Embodiment 2

[0045] In Example 1, a method of using Dynamo to realize the rapid modeling of non-standard parts in cement plant BIM design is disclosed, and step (5) in this method is replaced by the following method: the interface center of the downstream model is used as the reference center, and the interface is located The plane is the reference X-Y plane, by setting the values ​​of ΔX, ΔY and ΔZ to generate new entities and new interfaces, and repeating this, the values ​​of ΔX, ΔY and ΔZ are used to avoid primitives and comply with relevant design rules; for example: Input ΔX=0, ΔY=50 and ΔZ=100, and find that the non-standard model interferes with the concrete beam, then change the input to ΔX=10, ΔY=20 and ΔZ=200, and find that there is no interference and at the same time meet the design specifications, Then the modeling can be continued and repeated. During this process, the non-standard model is dynamically adjusted, and the non-standard direction is modeled from the interface of ...

Embodiment 3

[0047] In Example 1, a method for using Dynamo to realize the rapid modeling of non-standard parts in cement plant BIM design is disclosed. In this method, step (5) is replaced by the following method: the interface center of the upstream model is used as the reference center, and the interface is located The plane is the reference X-Y plane, by setting the values ​​of ΔX, ΔY and ΔZ to generate new entities and new interfaces, and repeating this, dynamic adjustments are made in this process. It is established by the non-standard model extended by the interface of the upstream model. The values ​​of , ΔY and ΔZ are used to avoid primitives and comply with relevant design rules. No more examples are given here. Refer to Example 1;

[0048] Taking the interface center of the downstream model as the reference center, and the interface plane as the reference X-Y plane, a new entity and a new interface are generated by setting the values ​​of ΔX, ΔY, and ΔZ, and this is repeated. Dyn...

Abstract

The invention discloses a method for realizing non-standard part rapid modeling in cement plant BIM design by utilizing Dynamo, and belongs to the technical field of building information models. The method comprises the following steps: a rotating center of a three-dimensional view is moved to a position near the position of the to-be-built non-standard part; the Dynamo is operated, visual programming is carried out, and after programming is completed, the Dynamo is attached to a Dynamo player and operated; an upstream model and a downstream model are arranged at the two ends of the to-be-built non-standard part, and three-dimensional edge lines of interfaces where the upstream model and the downstream model are located are sequentially selected; a non-standard number is input; non-standard trend is determined according to the related design rules and the primitives needing to be avoided by the to-be-built non-standard part; according to the method, automatic drawing is carried out through Dynamo until program operation is finished, so that a conventional model family with the name being a non-standard number is automatically generated, the defects in existing non-standard three-dimensional modeling are overcome, the design efficiency is further improved, and application of the BIM technology in a cement plant EPC project is enhanced and promoted.
