Swept surface problem/bug

Hi all,

I've got a simple closed profile of tangent arcs. My path is a straight line normal to the profile plane.

If I sweep this profile with 2 guide curves it works correctly. If I take the exact same profile and run the 'fit spline' command on it it will no longer follow the guide curves. In any possible combination it will simply follow the path and ignore the guide curves. (other than to get a bit of a twist).

I want the fitted spline obviously for a single surface. My profile of tangent arcs yield 8 surfaces.

TIA

ps. It's cool to know what you guys (who attended sww) look like!

Under options for the sweep feature, there is a checkbox for "merge tangent faces", its not on by default, did you check it?

It will depend on what you did with the fit spline. If you deleted the original sketch geometry that the spline was fitted over, you have also deleted the pierce constraints, so there is nothing to follow the GC.

Here's what I would try, but of course it may vary depending on the specifics of your situation:

- if you deleted the original geometry, make sure the spline is set to "proportional" and use the pierce constraint on the ends for the path/GC.

- if you didn't delete the original, make sure that you use the "constrained" option in the fit spline dialog, otherwise the spline will not change with the GC.

Thanks Matt,

Proportional was what I was looking for. I fuzzy memory was telling me it was a sweep option. Thanks!

Hi Matt,

Proportional was what I was looking for. My fuzzy memory thought that was a sweep option. Thanks.

BTW, if I do the fit spline 'contrained' where the arc'd profile was already pierced to the gc's, the spline does not change with the gc. So this may be a bug?
