Why do curves get thinner at 90° angles? Why do vector curves get smaller at corners?



In image, the width of the curve at point B (where it turns 90&deg; to the left) is smaller than at point A. This only occurs when cyclic is enabled.

How do I get both points to be the same width without disabling cyclic?
If you are beveling a curve in Blender, currently it will happen with the 3D mode because of the algorithm. You have to switch to 2D mode to solve that:
