Bevel not matching the curve object source I am trying to use the Bevel-Object field in the curve object. However the bevelled curve does not match the referenced curve in the X and Y direction (they do match in the Z direction).



The scales of both curve objects are at 1.00 for all axis. I think the problem might have something to do with the curve radius for bevelling but this is also set to 1.000 and I can only find a mean control value (not a value for the separate axis)

What is the best way to correct the difference accurately?

Turn the base curve to 2D. That will adjust the corners profile to the bevel object:



2D curves have limitation though: they need to be planar.

If 3D, the corner profile corresponds to the bevel object rotated 45°. So this is matter of choice.
