I guess I'm not after an elevational code as such - more something just to get it to recalculate / refresh / rebuild?
It seems that when I try my object and first place it and view an elevation, the object looks fine. It's then only when I view it in a second elevation that it appears skewed.
So what I need to do is to force the object to redo whatever process it first did when the first elevation was viewed, thus re-orienting the object to the new elevation. Something like the code to rotate an object to face the camera in 3D view.
If this can't be done then fair enough! Shame, as some really handy object could be made otherwise...
