I am having trouble creating a feature through a swept spiral that I created. Solidworks creates the cut-extrude in the feature tree but does not reflect it on the part visually. I attached a copy of the part.
Even after deleting and recreating the sketch and feature, The only way I can get the notches to cut through the whole length, is to make the helix non-variable.
First of all your sketch for the cut has a bunch of overlapping lines which tends to freak SW out. After that I'm lost. This is an interesting one.
Attached is an updated file with the overlaping lines fixed. I've tried almost everything I could think even saving it as a parasolid then opening the parasolid file and trying to extrude-cut the imported feature and I still get the same problem.
That's why I said this is an interesting one.
Part of the problem is you have multiple lines on top of each other.
The center arcs have 3 of the same entities.
I was in the middle of making that sketch from the size of the spiral to making it a little larger when I attached the file my mistake. Even if you fix my sketch it still does not show the extruded-cut feature on the spiral.
I'm not sure what you did, but here's what to do to fix it. First, delete the feature. Next, fix the sketch. Finally recreate the feature. Whatever you do, don't create the sketch the way you did the first time, that wasn't pretty.
I believe part of the problem was that it, the feature, was picking contours that just weren't quite right. I did the above and it worked fine.
Thanks for the help.
I created two seperate sweep features using constant pitch on both and the extruded cut worked with no errors.
