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 based on CAD data of water jet scalpel application. The method for generating the 3D model based on the CAD data of the water jet scalpel application comprises the following concrete steps of S1: unifying water jet scalpel data formats by CAD; S2: exporting a region set; S3: importing a 3VJSD file to brick paving software; and S4: when a front end user needs to use a water jet scalpel model, performing corresponding operation. The water jet scalpel model generation threshold is low; the method is easy to master and is quick and flexible; transplantation is convenient; the water jet scalpel effect is good; texture material replacement and size adjustment are facilitated; and the method can be applied to multiple 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...
