I have several iges files that I have imported in 2017 and converted to sheet metal parts. Believe my setting are the same for importing.
Now when an iges files is imported in 2018, I select the convert to sheet metal the part goes translucent and no surfaces can be selected giving
I have both 2017 and 2018 installed and now my 2017 is doing the same so one of the templates or data bases that gets overwritten when
you install 2018 has changed something. any help would be appreciated.
I have attached one of the iges files I am trying to covert.
