Hi Abe, probably the way you are currently doing it is the best for the moment.

But one of the last things I'm trying to get in for MoI v2 is mitered corners for a 1-rail sweep, which would be what you want in this situation.

The goal for this is to enable this initial structure to produce your result:



So hopefully not too much longer before that works better.

Currently you can try to do a manual corner mitering but I'm not really sure that it would be any better than your other method.

If you are interested, it would go something like this - start by cutting your curves in half since you can mirror it in one direction:



Now do a one-rail sweep, which will produce a kind of sectioned result along each segment individually like this:



So that part is easy, but now those pieces need to be managed - they need to be separated and rejoined into different chunks, then the somewhat tricky part is that you've got to place an precisely angled plane in there as a cutting object, and trim each of them to it like this:



After the pieces are trimmed with that plane, you'll have the proper corner:





The part that I'm going to be working on for sweep will be doing that same kind of a thing, but automating all of that.
