Wow that's neat. With almost all of your tools, they stew around in my brain for ages before I find a use for them. But knowing they are there keeps me coming back. Great job ggaliens.
Yeah ... a lot of these are there "Just in case". And "just because". Something like "select by hypotenuse". I mean ... why the heck not ? It is not in plain old wings3D. A fifth grader might articulate the function based on a triangle face selection.
If you can think of it that easily ... it should be available.
Gald you like Wegg. Perhaps helpful with a future cup-cake swirl.
P.S. Tighten helps to chill down the discontinuity that seems to happen at outside edge of swirl if you swirl too much. Works very well with tighten.
