Creo Parametric, sketch extrusion problem

[zpaolo]

Just dabbling with Creo 1.0 right now but I have a problem, if I do a sketch like this:

View attachment 5226

the extrusion looks like this:

View attachment 5227

the central "hole" is not present. Looks like there's a surface "tapping" the hole :/

I tried to recreate this, but was unable. It may be a graphical bug. Could you upload the part with the extrusion completed?

The first time I tried to reproduce the error it did not happen, after switching to the nmms template it happened, and now it's always like that. I'm attaching a simple part that in my system shows the bug.

As far as I can tell, it's just a graphics thing. There doesn't seem to be a surface there, or anything selectable. If i extrude off the top of the inner ring, the ghost "surface" disappears. Same if i extrude cut such that the inner hollow has a hole to the outside. It's not causing any problems with quilts or solidify. After changing my template, I could still sketch a new part that did not have the issue. But I couldn't make your part display properly. Here's one of mine that worked. Does it display right for you?

Yes your part displays right here, I'm puzzled, I noticed the bug after opening a WF5.0 file, then reproduced it with Creo 1.0... But you can see the "fake" surface too, so it's not a problem of my installation/workstation. I'd like to know where it comes from, maybe it's the template, who knows... Thank you for your time anyway

You're welcome. I tried one more thing - exporting to IGES. The fake surface doesn't make it through the export, so I'm guessing purely graphical. Good find though!

I just had this same issue on a simple rectangular extruded
cut. This is annoying.
I have logged a new case with PTC about this...hopefully
they will fix it in the next release.

heard back from PTC on this.

they will be fixing this in the M020 release of Creo, which
is due for release around end of September.
