How to add own flat pattern calculation rule?

[wowrs1608]

Hi,

For a roll, I want to use the mean radius to calculate the flat pattern length.

For example: a half round with 100 radius, 5 plate thickness. The flat sheet length needed to make this shape with be pi*(100*2+5)

How do I add this kind of rule to unroll the sheet metal part?

Regards,

Pete

k=0.5

Or setup bend table

Have you looked into the creating a custom unfold rule with the "Custom Equation" option?
