I got a problem with this part...first I created it as a solid part..then i converted it in sheet metal...but when I try to create a conversion then to create a flat pattern ...the regenareation faled....please smb help me to understand ...what I did wrong....
I can't understand why this won't convert in creo 2.0, it works fine in WF5. I have had quite a few issues with the sheetmetal functionality in Creo that were never a problem in previous releases.
I've attached the conversion created in wildfire 5 (box-1.prt.1), and also a workaround done in Creo 2 (box-2.prt.1). (I haven't done them to your dimensions though)
If you've got a maintenance contract with PTC I would contact them regarding this issue as it is obviously reduced functionality or a bug, and needs to be addressed.
Hope this helps,
had a further look into the problem. It appears that one issue might be that the blend you used was set to 'smooth' and not 'straight'. Also, the conversion worked in Creo 2 when I moved all the features so that the CSYS was at a corner, not in the centre. Don't know why this should affect anything but it works
