Watching the Parapet thread in Architect Forum led exploration of the Fit Walls to Objects:


1st, a thought -

The Fit Walls to Objects produces "curved" wall peaks as a series of short straight segments.  A) A preferred situation would be that at least arcs in the fitting shape are maintained as arcs. (other curves, too, but they are more complicated).  B) The FWO dialog could include a field to control the number of segments in the curved portion(s).

Currently, the only control I have found is to change the vwx 3d Conversion pref. Low seems most reliable.


Then, the bug - 

"Arc" wall tops or corners formed via the Fit Walls to Objects command are simulated with multiple peak points.

One end point of fitting surface arc may not produce a wall peak point.

Result is a wall top or edge which is not correctly aligned (eg level or plumb or other required angle).

Reversing the wall direction may change the missed point to other end of the fitting arc.


Workarounds include

•  Manually add/move wall peaks, or

•  Change the vwx pref for 3d Conversion Resolution to Low.

          3d Conversion at Medium, High or Very High all produce missed arc end.
