flat pattern for PFC (parallel flange chanel)

Hi

Can I assume that I would not be able to model in sheet metal a PFC section and obtain a flat pattern.

I assume this because for a 300 x 90 x 41 PFC the web is 9mm and the flanges are 15.5mm, so I do not have a constant thickness.

If this is the case has anyone got a work around to obtain the flat?

Thanks

You'll have to manually draw the flat pattern sketch and extrude that.

  Thanks Deepak,
  
  I thought that would be the case but thought someone must have come across this before and figured out a work around.
  
  Thanks

    Any specific reason you need a flat.
    
    Also the transition at the corner (specially inner side) would not be easy though.

The only way I would know how to measure the channel would be finding the center of the end profile sketch and measure that, as far as bending no.... Sheet metal is a constant thickness...
