Hi,

Im trying go get exp.: inside model sketch drawn in sheetmetal generic state to get on flated state precisely sketch location after flat form creating.

I need those entities (lines, points) for making dxf files after with open conture, so I dont use feature tools.
Im working in Creo 2.0, and I tried some combination bend-unbend but doesnt work.

sorry for my bad english

any suggestions,
thanx
