Unity add-on allows Unity users to utilize the CAD Exchanger SDK for CAD model import in the Unity game engine. Its main purpose is to convert CAD model files into Unity GameObjects and vise-versa. GameObject is the base class for all entities in Unity Scenes, including 3D objects. Both Edit and Game modes are supported, so that the capabilities of our SDK could be used not only in the Unity engine itself, but also in the applications built with it.
