Currently, OnScale cannot paramerise CAD imported models, parametric models must be built in OnScale using geometric shapes. However, using Onshape, a Cloud-based CAD system, dimensions of a CAD model can be parameterised and then imported into OnScale.
The following video demonstrates how a CAD file containing a SAW Model can be altered easily in Onshape and reimported into OnScale.
