Problems solved by technology

[0006] 2. Each of the existing software is designed for a specific field, and their data structure has the business meaning of the field
Moreover, their definitions of basic data structures and domain business-specific data structures are mixed together, making it difficult to expand
[0007] 3. Traditional desktop parametric CAD software has strong modeling capabilities, but they are limited by the computing and storage capabilities of the desktop, and cannot support the calculation of large-scale complex parametric models
Some emerging Internet design software such as Kujiale custom design tools do not have this limitation, but they are often limited to a certain subdivision field, and the expansion ability is limited
So far, there is no Internet-based parametric design platform with good scalability

Embodiment 1

[0131] Embodiment 1: as attached Image 6 As shown, in the field of mechanical design:

[0132] You can use its SDK to develop a plug-in on commonly used mechanical design software such as Autodesk Inventor, Solidworks, CATIA, CReo, NX, and convert the parametric model of the software into the intermediate data of the parametric model. For Autodesk Inventor, which provides SDK (Inventor Server) software that can read and write Inventor files, a stand-alone application can be developed to convert the parametric model of the software into the intermediate data of the parametric model. Since these software generally provide feature operations such as "chamfering", "rounding", and "punching", we can collect the parameters and geometric primitive inputs of these features, and summarize a set of common feature intermediate data structure. According to this, the data exchange of the mechanical parameterized model of a higher level than the general parameterized model can be realize...

Embodiment 2

[0138] Embodiment 2: as attached Figure 7 As shown, in the field of architectural design:

[0139] A plug-in can be developed on commonly used architectural design software such as Revit and Archicad by using its SDK to convert the parametric model of the software into the intermediate data of the parametric model. Since these software generally provide built-in components such as "wall", "beam", "slab", "column", and "staircase", we can collect the parameters and geometric primitive inputs of these components, and summarize a set of General component intermediate data structure. According to this, the data exchange of the architectural parametric model higher than the general parametric model can be realized.

[0140] If these component parametric design functions are also implemented on the general parametric model platform, then these parametric models can be imported into the general parametric model platform. After the general parametric model platform provides a seri...

Embodiment 3

[0145] Embodiment 3: as attached Figure 8 As shown, in the field of decoration design:

[0146]The 3D models used in the field of decoration design often come from 3ds Max, Sketchup and other 3D design software traditionally dominated by non-parametric design, and some models from parametric design software such as Revit are also used. For the Revit software model, it can be implemented according to the method in the field of architectural design. For models from 3ds Max and Sketchup, on the one hand, in recent years, 3ds Max 2018 and later, and Sketchup plug-ins such as Viz Pro, have provided varying degrees of parametric design capabilities. We can convert these models as much as possible into Parametric models. On the other hand, for the non-parametric models of 3ds Max and Sketchup, we can expand data structures such as polygon mesh and boundary expression, add them to the intermediate data structure of parametric models, and still transfer these models to general param...

Abstract

The invention discloses a cloud-based universal parameterized model analysis method and a design system, and relates to the field of computer aided design (CAD) software. The method comprises the following steps: 1, importing / exporting a parameterized model of any CAD software; 2, creating a universal parameterized model from a plurality of channels; 3, the parameterized model is calculated, stored and inquired at the cloud end; 4, displaying the parameterized model at the front end; 5, expanding the business support capability of the parameterized model platform by using a third-party cloud service; and 6, parameterized design software in each subdivision field is supported. On the other hand, the invention provides a universal parameterized model design platform based on cloud. The universal parameterized model design platform comprises a parameterized model universal data structure, a parameterized model intermediate data structure and a geometric model universal expression data structure. The method has the beneficial effects that bidirectional data conversion is carried out on a parameterized model of any CAD software; the advantages of cloud computing are fully utilized, andcomputing, storage, query and display of a large-scale complex parameterized model are achieved; continuously accessing a third-party service, and continuously expanding the business support capability of the parameterized model, such as a high-definition effect picture, a two-dimensional engineering drawing and the like; parametric design software of each subdivision field is developed with low cost, and parametric models of each subdivision field can be interoperable and deeply integrated in the same integrated environment.

Description

technical field [0001] The invention relates to the field of computer-aided design (CAD) software, in particular to a cloud-based general parametric model analysis method and design system. Background technique [0002] The development of computer-aided design software has roughly gone through several stages: 2d graphics -> 3d wireframe -> 3d solid, curve and surface modeling -> parametric modeling. The parametric model defines a series of parameters, geometric constraints, and algorithmic rules for generating the model, allowing users to easily modify the geometric shape, size, and appearance of the model by modifying only a few parameters. Its characteristics of full size constraints, full data correlation, and size-driven design modification have special advantages for generating a series of products with similar structures and different sizes, and for reusing product design data. [0003] Since PTC launched parametric modeling technology in 1985, various mainst...
