    I am doing hydrostatics for a complex multibody system. ORCA 3D Hydrostatics program keeps outputting double the expected displacement the system design draft. Has anyone experienced this issue before?

    Thanks for the advice! I just released that the major part in the system, which was imported from solid works into Rhino, had a shell feature in it. It created a shell in addition to the already existing solid body. ORCA counted both thus the displacement was double the expected value.

    When I retired and stopped using them on a daily basis (2018) Rhino and SolidWorks didn't always play nice together. Another issue between them is the surface normal, always check that.
