Frequently Asked Questions

How is scaling defined in the Unity plugin?

Length unit coefficient is taken either per input CAD file format convention (e.g. meters for Parasolid) or per explicitly defined settings for unit-agnostic formats (e.g. STL). This convention can be overridden though the Unity plugin-specific scale factor.

When importing B-Rep representation into Unity, how to specify triangulation parameters?

You can generate polygonal representations with the help standard CAD Exchanger SDK API (ModelAlgo_BRepMesherParameters) which accept pre-defined settings (coarse, medium, fine) and user-defined ones (for chordal and angular deviations, max edge size, etc). In the case of multiple polygonal representations, the Unity plugin will import all of them into the Unity scene.

How is CAD Exchanger SDK / Unity plugin licensed?

The plugin is licensed as an add-on to one or multiple CAD formats, per customer’s application, through the tier-based licensing model. Refer to SDK licensing, or contact us for further details.
