Hi

Could someone please explain the process to being able to unfold the incoming pipe in the attached Zip File.

I have a bottom pipe with an incoming pipe, I need to be able to unfold the incoming pipe to be able to produce a 1:1 DXF flat pattern drg.

I know I have to have a small gap to be able to unfold, however what would be the easiest way to produce this and how would i convert the pipe to a sheet metal part. I have tried 'convert to sheet metal' but  this has not worked. I must be doing something wrong picking edges / faces.

Also is there an easier way to do this type of work.

Thanks
