When using SplineOffset with the 2D mode the vertices of the generated splines all lie on a grid with spacing 1. This gives undesirable results, see the 1st attached image. As an example I used an arc but it does this with any spline.
When using the 3D mode it does seem to work, but then the 'end type' cannot be set. See 2nd image.
I don't see others having this problem. Is this some setting that i've missed?
