Hi Steve,

> I did not mention anyone else, please show me where I did!

You said that the result generated "may be OK for hobby stuff" - however, the result that I posted would be ok for a lot of different purposes, like someone more focused on just quickly getting a model for rendering, or for some design like a piece of jewelry that does not have to be exactly tubular to a tight tolerance, or a ton of different things.

Your statement is basically placing all these other kinds of people's work as just "hobby stuff", even though what they are producing is actually a part of their real job, it's just different from your job.


Of course, I can certainly understand if MoI is not the right tool for your job, if you have specialized requirements then use specialized tools.

Well, there were various different parts to the discussion earlier in this thread, that particular one I was giving an example of how you can't actually have a completely even thickness tube that has a common miter-like joint between 2 pieces that are curving around all over in 3D.

One that matches your definition of within tolerance and not the "oh-so-terrible" result from sweeping between angled profiles?

If so then by all means show it.

If you do a regular 1-rail sweep in Rhino it will produce this result:



If you enable the "Untrimmed miters" option, then it will produce this result:




Note from the slanted isoparms there, that this is a sweep between angled profile curves, which is the kind of result that you had earlier said was totally unacceptable.

Is it suddenly acceptable now?
