Problems solved by technology

It is difficult for ordinary brick laying designers to use software such as CAD or 3Dmax to generate water jet models
Because the cost of learning these software is high, it takes a long time and it is difficult, and the structure of the water jet is complex and the amount of data is large
For the models generated by these software, there is also a lack of flexibility

Embodiment 1

[0013] see figure 1 , the present invention provides a kind of technical scheme: a kind of method based on the CAD data generation 3D model of waterjet application, the specific steps of this method based on the CAD data generation 3D model of waterjet application are as follows:

[0014] S1: CAD unified waterjet data format, convert curves into multi-line segments, and obtain surface domain sets. It is necessary to unify water jet cad files into multi-line segment representations. In order to facilitate description of 3D data, we convert multi-line segments into surface domains. Waterjet Cannot be overlapped, the area in CAD needs to be processed by Boolean operation to obtain a set of areas that do not overlap but continuously cover the plane space;

[0015] S2: Export the area set, store it as a file in a specific format, export the area set as a data file in obj format, store the data information such as vertices and normals of the mosaic, and store another copy of the CAD...

Abstract

The invention discloses a method for generating a 3D model from CAD data based on waterjet application. The specific steps of the method for generating a 3D model from CAD data based on waterjet application are as follows: S1: CAD unified waterjet data format, S2: export area set, S3: Brick laying software imports 3VJSD files. S4: Front-end users need to use water jet models. The invention generates water jet models with low threshold, easy to use, fast and flexible, easy to transplant, good water jet effect, easy to replace texture materials and adjust size , can be applied to a variety of design schemes.

Description

technical field [0001] The invention relates to the technical field of water jet models, in particular to a method for generating 3D models based on CAD data for water jet applications. Background technique [0002] Waterjet has a wide range of applications and a large market demand. More than 80% of the design schemes of custom brick laying software have complex waterjet shapes. It is difficult for ordinary brick laying designers to use software such as CAD or 3Dmax to generate water jet models. Because the cost of learning these software is high, it takes a long time and it is difficult, and the structure of the water jet is complex and the amount of data is large. There is also a lack of flexibility in the models generated by these software. Therefore, in response to the needs of designers using water jets, a solution to automatically generate a 3D model of a water jet based on CAD data is proposed. Contents of the invention [0003] The object of the present inventi...
