Wrap feature failing - 'sketch has open or intersecting contours'

William Knapper Oct 20, 2016 11:04 AM

Hello,

I'm trying to wrap (emboss to 1/4" thickness) Sketch4 onto the front, concave face of the attached part. When I attempt to do so, it says "The Wrap feature cannot be created from intersecting or open contours". I've tried removing the middle construction line from the sketch, which didn't work. I also tried Repair Sketch under Sketch tools, but it found no gaps. I've done this type of thing with other sketches successfully, and I can't seem to figure out why I'm getting this problem now. Any ideas?

William,

If you edit your Sketch4 & zoom in (around D10 & D11), you will see some bad overlapping geometry. If you edit this so that it is a closed contour your wrap should work.

  Thanks, I cleaned it up, didn't realize how far I would have to zoom in to find that

    William,
    No problem. When in a sketch, if you're having issues, it's always worth using the "Check Sketch for Feature" tool, which can be located at Tools>Sketch Tools>Check Sketch for Feature....pick a useage from the drop down list (in your case I used the Boss Extrude option) & click Check & it will highlight any errors for that type of feature.

The issue with the sketch is in these two areas with overlapping geometry. I fixed that with the trim command. It looks like you wanted to make a fit spline for your Boss Extrude1 but you only made the rear arc line combination a fit spline. I deleted that fit spline then converted the construction geometry to solid lines and arcs. Made the front of the Boss-Extrude1 a fit spline then everything worked as expected. Of course maybe you wanted this on the other side. Not sure but should work either way.
