Offset curves on a surface

Feb 28, 2008 5 Replies

Is there any way to make a parametric offset to a curve on a surface? ie the offset still resides on the surface. We can then control the offset dimension for different configurations.



You're not going to like this...

Make a sweep surface using your original curve as the guide curve. Section is a circle centered on the guide and radius = offset distance. Intersection of face and sweep surface = offset curve (roughly).

Here are two workaround methods using a trim or split and offset surface to get the offset curve/edge..

I know this has been requested in the past and it clearly is not a priority for the majority of users but I would guess this is accessible thru the api?

and, another option with the face split, select the edge,.. use the Ruled Surface, Normal To.

That might work. Obviously it is not a true offset but our curvatures are large so the difference in the true offset and this type of offset would probably still be within manufacturing tolerances.

Thanks
