Hi mcramblet, there has been a new draft angle extrude (called Tapered extrude) added in to a recent v3 beta, some details on it here:

That's not in the trial version yet though since it's a new feature for v3 and v3 is not yet finished up.

For v2 the workaround method was to use Offset, then Move, and then Loft, see here for some examples:

Also a related video for the calculation involved here:

Thank-you for the information, I'll check out those links. With the new features of v.3, it looks like I have another reason to purchase a copy of MoI, ASAP.

There's a collection of all the stuff that's new so far in v3 (all the v3 beta release notes) here:

But I still want to add in more stuff yet before it's finalized.
