I need to create a hollow cylinder surrounding a separate cylinder. How do I do this?

Thanks in advance,
Daniel Frantz

I would have a Work plane, draw two rectangles and rotate the workplane. See attached.

Hi,

You can create the outer hollow cylinder using the Surface type instead of the default Solid type. The outer cylinder then consists only of the cylinder surface. You can close the ends, if desired, using Cap Faces features if the license includes the CAD Import Module or by defining work planes at each end where you add a circle that matches the end of the cylinder. Note that the interior of the hollow cylinder is void, so you cannot define any physics in that part of the geometry.

Best regards,

Thank you for your help! I was unfamiliar with the revolve function and your advice allowed me to build my model.

Thanks again!
