referencing / grouping

3D assemblies created for the technical design and construction of a product are usually grouped according to the installation or function. For 3D animations and 3D interactive it’s required to check whether all movements can be performed with the existing structure. If necessary, further movement groups get created. In a second step, the individual parts get sorted per assembly according to their material. Existing material assignments get reused whenever possible. Assemblies with multiple applications get optimised once and referenced as instances at the different positions.
