Hi Anders, thanks for the reply. I checked that already it says if it is cylinder but I'm looking for a way to find out an easy way to pre-rationalize sub-surfaces which are not cylinder but close to cylinder so I can convert them to cylinder surface later! if it make any sense to you . . .
Do you any easy and basic way to check if a double surface cab get converted into cylinder surface? Basically for fabrication to check if I can reduce the cost by converting few double curved panel and get more or less the same result!
I figured that out, now I'm looking for way to convert text to one single curve (to save time for laser cutting). At the moment i get the out line of text as curve which is great but still time consuming.
