Distance between two Bezier curves I have curve modifier applied on 3 extruded planes. The curves and planes all have the same width and the curves have the default handle values.

My expectation was that since the distance between the two curves throughout the curve extent is constant, if at one end the objects are just touching each other, at the other end also they would touch but not overlap.

I notice, however that at point 1 of the curve there is considerable overlap in the objects. Could you help me find the reason and the resolution of the issue.
The "distance" between them may be the same in the direction of duplication (ie. global), but not in the direction of extrusion (ie. the normals of the curve).

One solution to fix this is using the same curve to deform all your planes, just give each of the planes the right offset in object mode.
