A Sketch that won't Extrude

[bpenza]

Thanks for any help.

A student of mine has a sketch that he cannot extrude.  I have looked at it and cannot find anything wrong with the sketch  (ie. overlaps, disconnects).   We are using PtcCreo 3.0

Here is a copy of the part.

If someone could tell us why this won't extrude or even better, how we can do a check for future sketches,  that would be great.

Thanks. very much.

Hello Brett Penza

or just share your sketch ( *.sec file). Hope we can open it under commercial licence.

I can't open it either but it's possibly an accuracy issue if you have relatively small edges on a large sketch.

Hi,

I created Extrude feature and it failed. Then I displayed feature information - it contains following explanation ... Reasons for failure: This feature is defined with dimensions that are very small compared to the rest.

Then I changed Relative accuracy from 0.0012 to 0.0001. After successful regeneration, feature was displayed in graphics window.
