CAD Checker

Analyzing large CAD data for performance bottlenecks

With CAD Checker an imported CAD file can be checked. This is mainly usefull for verly large assemblies for detecting performance bottlenecks.

This includes

• calculation of triangles, static meshes, and non-static meshes

• detection of the largest meshes for further optimization

• detection of unnecessary mesh duplicates for performance optimization

CAD Checker Window

To open the CAD Checker window please select realvirtual> CAD Checker (Pro) in the realvirtual.io menu. This will open this window:

Checking the meshes in large CAD data with CAD Checker window

In the window, you can get a quick overview of the triangles in the model and the optimization possibilities. First, you will need to select the level of the model you want to check under Check this. If you select upper part naming the name displayed in the first column of the mesh list is the name of the Gameobject one level above the mesh itself. This is the usual setup for most imported CAD data. Next, you should select if you want to see all occurrences in the model (what means all identical meshes) in one line or as separate lines. To detect duplicates you should select Show Occurencies. Now you can see the total number of meshes and triangles in the model. The list is displaying you all meshes sorted by the total number of polygons. This means that _CarrierA in the model has in total 372912 Polygons with 34 occurrences. That means that 34 identical meshes are in the model. These meshes make 372912 Polygons. But there are also 10 Duplicates in the model. Duplicates are identical meshes with identical positions. Usually, you should prevent to have duplicates in the model because they are normally unnecessary.

The statistics also show the number of static meshes. Please take care, for performance reasons, that all components that don’t move inside your model should be marked as “static”.

With Show you can Ping the object and with Filter you can display all the components isolated. With Select you can select all components and with Duplicates only the duplicates are selected.
