How to Open Step File in VTK

Who can tell me how to open the STEP file and display it? Thank you!

You may read the STEP file with OpenCascade kernel and then visualize it in a VTK scene after faceting (generating visualization mesh from a CAD model). Here is the project where this workflow is readily available: https://gitlab.com/ssv/AnalysisSitus
