A lot of times when making sheet metal parts setup for laser and cnc brake, or tube laser cut parts – my total roll out value or flat pattern dimension does not come close to the actual sheet size I need for converting the part into a flat *.dwg. Why is this? For example… if I flatten out the image below I may measure short on the actual sheet size needed to phyically make the part. I’ve adjusted k-factor, physical properties and sheet thickness to compensate but I can’t seem to get any consistency to the rollout/flat pattern.
I’m using SW 2011

Thanks

I”m running SW 2011… I’m importing a .x_t file, it comes in fully defined, but the inches show in mm and 100x the numeric value. Any suggestions to fix this? I know the real size is 4.11″

  Choose inches or mm conform the requirements to units, than use Scale Feature using the right ratio.

  When trying to open the file you will see an options button on the open dialog. Hit that and set the units to what you need.

Rolled edge, round tube.
Hello.

I’m looking to take some 2-d production drawings to 3d for our company. I’m having troubles creating a rolled edge on the end of round and angle cut exhaust tubing. Suggestions? SW 2008.

I seem to be limited to a rolled edge being only on a flat edge. I’ve tried to reapproach the idea from different angles with no luck.

  Are you looking to have a flat pattern from this? If not then do not use sheet metal tools to make the part and you should be able to revolve a profile

  Can you put up some pictures or files here to explain what exactly is the issue or what you trying to make.

  From California Jay…
  
  After a few more minutes of looking at it i got it… I forgot to add a guide curve to a sweep. this enabled me to square the one end. Thanks guys.

  Is this what you were referring to? It is just a filleted edge on an extruded cut through the tubing.
