Hi Ed,

> I assume using two different shaped profiles is OK?

Yup, it should work fine, just like the example you show there.

If there are a different number of segments between the shapes, it will still work but you will get a lot of kind of funky surface stripes in the in-between part where one shape kind of morphs into the other...

If you have the same number of segments between each profile you will get a cleaner type of 1-to-1 matching between the segments.
