    Hi Boris,

    Here are three options to consider:

    Option 1: Use a Coupler joint. See: How to Crete a Lead Screw in Inspire Motion

    Option 2: Use a State Dependent Input (translation of screw is a function of the rotation of the screw rotation). See Inspire Help: State Dependent Inputs

    Option 3: If geometry is sufficiently accurate, define a contact between the screw and nut. The interaction is all geometry-based in this case - screw rotates, and as a result of the thread geometry, the nut translates

     

    Hope this was helpful.

    Regards,

    Hello Boris,

    Which product are you modeling in, Inspire Motion or MotionView?  Methods can be different based on available modeling entity types.

    Kind regards,
