Question

Missing Set Datum Axis

Gurus,



I couldn't find a solution in the archives but I thought I'd ask again. I have an extrusion which had two features (holes). One of the holes axis was set to Datum C. Somehow someone was able to redefine the sketch and delete the hole which had the Datum C. Now we have two problems: 1) I cannot delete the extrusion because it says it is tied to a Gtol and 2) I cannot set another axis to Datum C because I get the old "name already exists". How can find and delete this datum?



Wildfire 4.0 Datecode m170

Windchill 9.0 Datecode m030



Thanks,

Eric

Still not working.

I deleted all GTOL's and I still get the "name already exists". Anyone else have any ideas before I remodel this part?

Thanks,
Eric

Eric,

Various types of features can be named. Possibly another type of feature has
this name. Pro/e doesn't make a distinction. If you can find it, maybe you
can delete it or rename it.

Eric,

This typically happens when a Gtol Datum has been placed on an "&ad" dimension instead of the model driven "&d" dimension and then that dimension gets erase in the drawing. I have yet to find a solution to this issue, except to not ever use on Dim for the placement of Gtol Datums. If you are very diligent about only using show/erase dimensioning and driving your drawing dimension as the model dimension you should have better luck and not run across this again. (hopefully). I know this may not help but, the only solution that I have concluded is avoidance.

Everyone... please shed some light on this if you know anything further.
Thanks,

Apparently this is a bug. You should not be able to delete a feature that has a datum reference but if you do then you are sol.
However; if you send the part to PTC they have a diagnostic tool that can find these missing / reserved datum's and delete them. I sent them my part and they fixed it.

Thanks,
Eric
