Splitting a body in multiple bodies(Sheet Metal)

Hey,

We've always built our trailer beams using weldments. When using weldments, what we do is generate the trailer's web and then the trailer's flange and after that we split it to whatever length we require it to be manufactured.

The problem I'm having right now is that we're using the split feature to split a bent flange. The split is done somewhere inside the bend. What that causes is that the part gets a sort of angle cut because the split feature doesn't do a ''Normal cut''.

Does anyone have any idea if there would be a way to work the same way and have a normal cut?

I pointed in Red the flange that I speak of.

These corners are not ''Normal cut''
