Importing a CAD Model Into OpenSim

Post by KATHLEEN BALFOUR » Mon Aug 01, 2016 12:24 pm

Hello!

I am working on analysis of Ergometer- rowing using OpenSim.
Could someone help me understand the full potential of OpenSim for importing CAD models?
My goal is to import a CAD model of our Ergometer to act as a constraint to the model.

Thank you!
Kathleen

There is no CAD support in OpenSim because there is no standard format for joints, constraints, etc. Whatever model you build in CAD, you would have to build from scratch in OpenSIm. The only thing you can do is use the geometry meshes from you CAD model (.stl or .obj formats).

Kathleen, what CAD-system do you use? I developed an extension for CREO (Pro/Engineer) that can convert open chain mechanisms to OpenSim multibody models. Please contact me if you want me to convert your assembly.
