When I construct a slope from a line to a surface, I get a wrong result! TBC creates the blue line, but the yellow line is correct.
I know that this issue is described in the TBC-manual and you can get a better result if you reduce the step size, but that is not practical. With a small step size I get a lot of unnecessary points on the slope line and therefore a lot of unnecessary triangles in the surface.
Other CAD programs recognize the triangle edges of the target surface and only calculate the intersection points with the triangles.
