How to use "find-isomorphisms" command?

[Winson]

Hello,
I want to test the Tcl command "find-isomorphisms", but I don't know how to input the right parameters <varShape>.
Whether the pre-operation is required to obtain <varShape>?
Looking forward to reply! Thanks!

Hello @Winson and welcome to the forum.

Select faces, right-click, then "set as variable" will give you a pattern to match.

I would be grateful to hear about your thoughts on this algorithm, if you happen to have any.

Thanks, this algorithm has inspired me greatly.

After "set as variable", how to save the model data for reuse?
I used "Part->Save to->BREP" or "select variable -> right-click ->Save to BREP", but it didn't work, the model's shape is empty.

Might it be that after loading a BREP file you have the visibility checkbox for a part turned off?
