Alain and Stephen S
thank you for your previous help but I got stuck one more time, the picture
below explains nicely why I am stuck. Can you tell me what am I doing wrong?

Alain and StephenS , sorry if this is a repost.
I solved the problem partially, if I change the length on a side of cabinet
bezier_spline stops working correctly, it disappears altogether.
The picture below explains what's wrong, I thank you for any help you provide.

Your last point needs to be the same as your first point (0,90) or povray will
add another line to close the prism. This may be causing you problems.

StephenS
thank you very much, you are right opening and closing points must be the same
(0,90) in this case. I solved my problem for now, but since the cabinets side
measurements are changeable by the user I hope I can get the curve's (2nd and 3
rd) points correctly calculated. I am trying to figure out the algorithm for
that. If any formulas come to mind I'll be thankful for any idea.
appreciate everything,
optima

When using a bezier spline, the last point of any segment MUST be the
same as the first point of the next segment. Also, the last point of the
last segment must be the same as the first point of the first segment.
With that kind of spline, there is no auto-closing as there is with the
other spline types.

The last point of segment E is not the same as the first of segment A:
<0,115> VS. <0,90>
When using bezier spline, there is NO auto-closing of the shape. If the
spline is open, it disapears completely. That's because you can no
longer unequivocaly determine if any point is inside the prism or not.

Thank you Alain , I solved the problem of bezier_splines with your and Stephen S
helping.
