What's happening - I create a Shape then go to Extrude Shape to FreeForm>Fixed Height; it says Identify Shape; but msg: ERROR - the baseshape is perp to the sweep direction.
Generally no such problem in analagous Solid Modeling tool Solid by Extrusion - tho I have seen that insisting on extruding in the plane of the shape, not perp to it.
Thanks, just realised that - wonder if that also has bearing on item 1 of
communities.bentley.com/.../97458.aspx
OK, so is not gd enough to just rotate Adraw compass so xy is parallel to the Shape, so z is perp to it and parallel with the direction of extrude. It also has to be rotated so z +ve points 'back into the screen' = the direction of extrusion (if Fixed Height>Height is +ve). Any other Adraw compass rotation produces ERROR - the baseshape is perp to the sweep direction.
Is that correct?
If so, how fussy is that? BD 'knows' it's going to extrude in one direction only - so why need Adraw to confirm it?
I checked Extrude Shape to Linear Form and it's totally indifferent to Adraw compass rotation.
So why can't Extrude Shape to FreeForm be equally indifferent?
Unknown said:Is that correct?
Yes. That is correct. I agree it is rather fussy and probably should be indifferent to which face the accudraw compass is aligned. Although in theory, I could see a case where I might want to chose the exact axis of a rotated compass. Perhaps that unusual case where there is ambiguity is the reason for the required precision in the settings. Perhaps it is worth filing a Change Request.

Well I wd agree, if a FreeForm is capable of extruding in a direction not perp to the base Shape. But AFAIK any such attempt gives that ERROR message. Am I missing something?
The dialog won't accept a negative extrude Height either AFAIK - correct?
Which way it decides to extrude is also a mystery - thought it was 'back into the screen' but not so sure now. It only consents to extrude one attempt out of five so it's hard to test - too many possible mistakes to handle at once!
I can't fully follow the English here.
But I have no problems extruding to Free Form in both directions +1000 / -1000 in an iso view.
But I don't think that it can be extruded non-ortogonal to the shape. And I suspect this is to make Quantify to work.
Solid by extrusion can extrude non-orogonal.
