Hello friends, I am working on a 3D geometry of an artery and I want to create a shell for its walls. Naturally, some parts of the shell should be thinner. How can I create a shell with different thicknesses in different areas of this artery?
Hi Alireza - I think you’ll need to create both surfaces independently - I guess you may be able to start the ‘other’ surface from the first by offsetting with the Loose=Yes option, or possibly
Rebuild the offset, and then manipulate the surface points to match your data.
Hard to say without an example…
If you do not need high accuracy, MultiPipe command is the fastest way to make inner surface. Making outer surface is more difficult - you have to offset closed curves which represent cross-sections and loft the curves.
Thank you for your response dear friend, but I am still confused and don’t know what to do. Consider the shape I sent as an ideal example. Suppose I want all the geometry to have a solid thickness of 2 millimeters perpendicular to the y-axis, but at the same time, I want the thickness around the drawn circle to be less, i.e. 1.5 millimeters. Can you give me a solution?
And I should note that I have only stl from main geometry.
And need a stp file for shell
I guess the only way to do that right now would be to shell the different wall thickness parts independently, then merge them together and manually edit/manage the transition areas.
Your suggestion is correct, but what command do you recommend using?
