# CAD import (Pro)

Unity is able to process standard mesh-based file formats such as fbx, obj and collada. Mechanical design systems (CAD systems) are usually not able to process these game-oriented 3D data.

realvirtual.io Professional includes [CADLink (Pro)](/basics/cad-import/cadlink.md)for importing CAD data. CADLink allows you to import CAD files from any CAD system that can export step or 3MF files. Another option for importing 3D data is to use the PIXYZ plugin, see [https://unity.com/de/products/pixyz.](https://unity.com/de/products/pixyz)
