Michael -

Thanks for the additional info on working with crossed tubular designs.

After experimenting with the extrusion & fillet method, I decided it works very well for my needs. Plus it's fast and nothing needs to be tweaked. See render below.

Your comment about increasing my ring model size x10 is well taken. The fillet did not work until I scaled everything up x10. It's easier to work with actual dimensions (even though mentally dividing by 10 is not a deal breaker). Is there a way to apply a scale factor so that I can work in actual dimensions, yet have the model larger so these kinds of issues can be avoided? If not, I guess I can work in feet rather than inches.

Again, Flow works very well and I'm looking forward to using it.
