I'm glad it worked so far. If the Addon-Modules like Netgen/Tetgen/Geocon don't work properly,
you'll have to adjust their respective paths (so you're right on that).
Click on the menubar > Help > Options > Paths and select the following
In your case, replace [homedirectory] by /Users/OIk/.
Secondly, there is no z88i1.txt as the meshing has not yet taken place, but the geometry is already
imported, indicated by the existing z88i1_stl.txt (although it is not shown). Just open your project
folder again with the changed paths; you'll see no structure but when you mesh the part (with the
existing z88i1_stl.txt in project folder), you'll see the meshed component.
Tell me if it worked.
Good luck and best regards,
