Hi Steve, looks like you have got a great method worked out, the results look nice.

Yeah, filleting is a pretty intense number crunching operation, so it is not unusual for it to take about that amount of time. The time for that operation is directly proportional to the speed of your computer's CPU - that would certainly get faster on a computer with a faster CPU.

One thing that can also bog it down somewhat is if you have objects at a large numeric scale, like with coordinates larger than 1000 units or so. MoI computes many operations to an accuracy of 0.001 units which can be too tight of an accuracy if you have objects at a larger scale size. That is not easy for me to tell by looking at the screenshots, but you possibly may be running into some of that as well.

Solved the problem, Michael, I'm happy to say.

I had the mesh angle turned down to a very low value. I also swithed off "detail to inflections" and now the fillets happen super fast. Nice :)

Here's another thing I found:
With some letters, S in particlar, if I fillet the vertical edges, then the top face will not fillet. It would probably be better to fillet the original 2d curves before extrusion.
EDIT I withdraw this comment. Problem solved by slightly reducing the fillet radius

By the way, it's great to be able to turn hidden lines on and off from the view menu. I don't think that feature was there in v1. And the C-plane feature will definitely come in useful.

Hi Steve, sounds like you have got things under control now!

Thanks, yup that is new for v2. I'll probably be putting various other view options that you may want to turn on or off relatively frequently over there where you can get at them a bit easier, rather than only on the Options dialog.
