Offsetting spline possible?

Richard Morrison — Tue, 11 Nov 2003 19:23:19 GMT

This seems like a pretty basic thing, but I can't figure out how to offset a spline. Trying to create a "snaky" walkway. (Offset tool and magic wand don't seem to work with this.) Thanks.

I do not think it does work, you can magic wand a spline with the arc tool, this will produce a close approximation of the original spline.

Correct, you can't "Offset" a "Spline" with the Spline Tool - only the Curve/Arc Tool.

Splines depend on vector directional user input at each vertex during creation.

It would be nice though to able to offset a Spline with a Spline. That's one for the Wishlist.

Thanks, Bill -

That solution hadn't occurred to me. This looks good enough that I can live with it!

There's been several times I've _really_ 'looked for' an 'offset' tool ... one work-a-round (mebbe worthwhile for some situations;
This is from memory but should explain the principle?

Magic wand a bendy wall to the spline. Save as dwg. Open a blank S/E window. Merge dwg. Kill duplicates. Copy / paste.

Not as complicated as it sounds but 'oh for an offset' ... and sometimes walls have 'problems' with sharp corners!!
