Hi Burr, oh I guess you were talking about the case where the curve is actually planar within tolerance itself but at some angle to one of the main axis directions. You will get a default extrusion direction that follows the object's own plane normal in that case.

The one I showed above is for when the curve being extruded is not itself planar within tolerance.

Note that by having each object follow its own natural extrusion direction it allows things like this to work all in one extrusion step:




If it asked you for a single extrusion direction at the beginning of the extrude it would not be possible to get the "batch extrusion" result above from just one extrude anymore.

Sorry I got confused - I was thinking of the case where the object being extruded is not itself planar. For that case it does pick a world axis direction as the default rather than some skewed direction.

But if the object that you are extruding is itself planar within tolerance it will use that object plane direction as the default like you were thinking.

The more that objects use their own built in properties helps make things work with multiiple selection "batch mode" type stuff.

If you have an object that's planar within tolerance but on some slightly angled plane, I'm not really so sure that making a world-axis extrusion from that really fully fixes the problem...

Probably the profile ought to be flattened in that case. But it's kind of hard to do that automatically because the question then becomes how much deviation do you allow before stopping the auto flattening from kicking in. If it kicks in too easily then you can't make something at a slight angle when that's what you actually wanted to do.

I've thought a little bit about having some more information in the properties panel for whether the current selection was planar or not.

Hi Michael

Thanks for the answer, I can't believe that in over 1 year of playing with MoI, I never noticed this behaviour before :(

Got it. I've been really looking forward to the "extended properties panel". i think this will be many answers/wants in one...I DO think what we've been getting is more deserved, or warranted though...
