Missing lines for curved objects in elevation AC09

[Eduardo Rolon]

Need help with this:
For a project I am working on I had to create some curved elements (walls and object) after drawing them in plan and switching to elevation I noticed that the elevation was missing some lines from the shape (see attached). The object was created using profiler and the result in the elevation is totally unacceptable. I tried recreating the object, changing all the elevation settings, changing the scale and I can't get AC to draw the complete shape. For curved walls the same thing happens when the curve is 180 dg or more with the added problem that if it is a 360 wall then you get an extra profile line (in the part that is drawn) that does not clean up, the separation between the lines is usually 1/16". I also tried changing the 2d redraw options to full model and turning OpenGl for 2d on. I also created a circular slab and used magic wand to create the walls which gave me the same effect and playing with the magic wand settings did not help nor just drawing the wall by itself.

What am I doing wrong?

Dan I agree that it is not an ideal solution and the problem is very specific since it only happens with curved walls that are 180 degs up to a complete circle. If the arc is less that 180 you don't have to worry about matching reference lines or rotating the wall start point.
Normally I would not have to work with this since I don't care to much for cylinders in architecture, but that is the shape the client (who is an architect also, so there is no much leverage to change the shape) wants.
So this is definitively a BUG...
