extrude along path tool doesn't work

[domer1322]

I?m not sure if this should be a bugsubmit or a wishlist item, but I want to bring attention to this issue. The ?extrude along path? tool doesn?t work as it should in VW 12.5.2 Windows. Try this for yourself: draw a polyline shaped like the number 5 (with corners) and convert it to a NURBS curve. Then extrude any shape along the path?.... it works fine. Now, take the same NURBS curve (before extruding it), and pull any vertex into a different ?Z? height so that the NURBS curve is no longer planar. Now the ?extrude along path? doesn?t work. Try the same thing again, except this time use a NURBS curve that is shaped like an ?S? without the sharp corners. It works just fine under both conditions? whether the curve is planar or not. Oddly, the extrude along path tool works with non-planar NURBS curves if all the vertices are corners (first degree vertices).

Can anyone testify if this same problem exists in VW 2008?

Domer - Can you either post a file or email a file?

I don't know how to post something .. I sent it to the email you listed moments ago. Thanks for looking into this.....

this is has been discussed before, but NNA either can't replicate the problem as described or aren't interested...

try the 'loft' tool, it fails less

good luck

The sharp corners is something currently not supported.
