Problems solved by technology

There are many defects in this method, for example: 1. The section of the component is not perpendicular to the horizontal plane; 2. The models at the intersection of the broken lines are discontinuous and interlaced; 3. It is difficult to make variable-section components, etc.
The model established in this way has low accuracy and poor applicability

Embodiment 1

[0042] Example 1, such as figure 1 , figure 2 and image 3 Shown:

[0043] The parametric modeling method of special-shaped components based on the secondary development of Revit includes the following steps:

[0044] (1) Make parameter information table

[0045] Establish parameter tables according to municipal engineering design drawings. According to the accuracy requirements of the actual project, a section is selected at intervals on the route. The parameters are obtained from the section of the structure at the corresponding mileage on the route. The parameter value will include dimensional information such as the three-dimensional coordinates (X, Y, Z) of the section position, section height, section width, and section rotation angle, as well as topological information such as whether it is an entity or a shear. Store the data obtained from each section in turn into the designed table.

[0046] (2) Make parametric section profile

[0047] Establish parametric c...

Abstract

The invention discloses a parametric modeling method of abnormal component based on Revit secondary development, which belongs to the technical field of BIM and can be used for three-dimensional modeling of complex abnormal component in municipal public engineering. The method comprises the following steps: (1) preparing a parameter information table; (2) making parameterized section contour; (3)Fabrication of segmental families of special-shaped members; (4) Project automatic assembly. The method can solve the problem of three-dimensional modeling of spatial abnormal structures in the fieldof municipal public works, increase the modeling efficiency and improve the modeling accuracy.

Description

technical field [0001] The invention belongs to the fields of building information model technology and municipal public engineering design, construction and detection, and in particular relates to a parametric modeling method for special-shaped components based on Revit secondary development. Background technique [0002] BIM technology is a revolutionary technology in the construction industry, which can play a huge role in the refined management of projects and the management of the whole life cycle of buildings. With the continuous promotion of BIM technology, this technology has achieved fruitful results in the field of construction engineering. However, in the construction of municipal facilities, BIM technology is still in its infancy, and related technologies are still immature. [0003] As far as the actual application of BIM technology is concerned, the Revit software developed by Autodesk is the most widely used. Although Revit software has many advantages, it l...
