Which surface has better function, catia or UG? Designers.

Catia is superior to UG in surface function.

CATIA has a powerful surface design module.

1. Universal shape design

GSD(generative modeling) is a very complete curve manipulation tool and the most basic surface construction tool. In addition to all curve operations, it can also complete functions such as stretching, rotating, scanning, boundary filling, bridging, repairing fragments, splicing, concavo-convex, cutting, smoothing, projection and advanced projection, chamfering and so on. The continuity can reach G2 to generate a closed body, which completely realizes the surface modeling function of ordinary 3D CAD software. Fully parameterized operation.

2. Freestyle surface

The abbreviation of FSS, free style modeling, is almost completely nonparametric. In addition to all the functions of GSD, it can also complete surface control points (control points and deformation can be adjusted synchronously from multiple surfaces to the whole product shape), freely constrain boundaries, remove parameters, realize surface bridging, chamfering and fairing of automobile A surface standard. All commands can reach G2 very easily.

3. Automobile Class A

ACA, automobile A-class surface, is completely nonparametric. This module provides powerful curve and surface editing function and extremely powerful one-button surface smoothing function. Almost all commands can reach G3 without destroying the original smooth shape. It can realize synchronous surface operations (control point dragging, smoothing, chamfering, etc.). ) and even the whole product form.

4. Freestyle sketch tracker

FST, freestyle sketch drawing, can draw basic shape curves according to three views or photos of products.

5. Digital shape editor

DSE, digital surface editor for short, samples, edits and cuts according to the input point cloud data, which meets the requirements of the closest product shape and can generate high-quality mesh triangles. Totally irrelevant.

6. Rapid surface reconstruction

QSR, referred to as rapid surface reconstruction for short, provides a variety of ways to generate curves or small triangles after meshing according to the input point cloud data for surface modeling, which is completely nonparametric.

7. Shape sculptor

The shape editing of small triangle can perform various operations on small triangle, which is almost as powerful as CATIA surface operation and completely nonparametric.

8. BIW fasteners for automobiles

Body-in-white fastening, welding method and welding geometry design between body-in-white sheet metal parts.

9. Images and images. shape

You can drag, stretch and distort the product shape like plasticine, and add "image shape" to achieve the ideal design shape. The conceptual design of product shape can be completed quickly.

1~9 is included in the shape design &; Modeling module

10. Healing Assistant

An extremely powerful surface repair tool can automatically find and repair all kinds of broken surface defects.
