Sweep1 Untrimmed Mitres option counter-intuitive

Shouldn’t the label be Trimmed Mitres, not Untrimmed Mitres? Selecting Untrimmed Mitres gives you trimmed ones, unselecting it gives untrimmed ones.

Checkling… thanks.

Hi Jeremy - here is what I get sweeping a circle on a polyline -

Hi Pascal,

To be honest, I’m struggling to interpret the wireframe.

Here are some more examples. In each case I’d call the top one untrimmed and the bottom one trimmed, whereas rhino has it the other way round.

Incidentally, note how when the circles at the ends are different radii the unwanted parts are much more apparent.

Hi Jeremy - the real test is to explode and turn on points for the surfaces - untrimmed miters will end at the miter and only have two surfaces meeting. (Untrimmed is defintely compromised in cross section in many cases…)
