Sheet Metal, Bend Deduction, as must have for manufactures

Hallo,
we as a producer mis the possibility to add a deduction table for the bending process.
The K-Factor is okay for developers but not fr the manufactures.
As I saw in old discussions you want to do this, but since 2018 nothing working was added.
This is a main point not to use Onshape.
The Radius will be depend on the die and the angle and not to the drawn model.
So the k-factor won´t work.
It needs to be just on the angle, what a bend table with deduction do.
The data base behind the machines also use a table with deduction instead of k-factor to make it right.

K=(LOG(IR/Mt)*0,5+0,65)/2
We get a lot of parts with different Radius at the same Material.
This is why we use a bend table, so we can ignore the radius, we have on all the same deduction, just with the thickness the angle and the die as settings.
And there are just few die for each thickness.
SW, Inventor, Trumpf and others, all work with a bend table and deduction.
This values we get directly from the bend machine producer.
