Visualize bend zone on sheet metal
I often find that one of the main considerations when designing sheet metal parts is the minimum flange length. This is determined by the pressbrake tooling chosen to bend it. What I am proposing is a very simple and visual way for a designer to know where the edges of the tooling are.
The implementation in Onshape could be simple. An optional field to enter or select the width of the die in the sheet metal properties window would be perfect. The output would be a visual representation of the bend zone on the flat pattern view within the part studio.
This idea comes from using Bystronic Bysoft to program parts for the pressbrake. The picture below is snipped from that software. The yellow shows the edges of the die and the blue is the bend radius area calculated from the punch selected and the thickness of the metal.
You can see from this visualization of this part that the slots should have been moved ever so slightly away from the bend line to ensure there is no improper material deformation. Also, notice that the different dashed lines denote positive/negative bends.
For comparison, here is the same part in Onshape.
