K-factor on an imported sheet metal

Hello, I have a question about the k-factor after doing sheet metal function recognition on an imported part.

The K factor does not seem to have an influence on the dimension of the unfolded, is this normal or did I make a wrong handling?

I'm on version 2017 SP3.

Thank you for your answers.

If you change the K factor

You also need to Delete the old Unfold

and make another one

made a record before 

And after modification

and control the diff

@+

When you mean delete the old unfold: is it to put it in a state of deletion or to delete it completely (I don't know if that's possible)?

It depends if you change the bending radii because otherwise it won't change much.

Hello, if you have several folds, be careful to modify the general K factor and not that of one of the folds!

Kind regards.

"It depends if you change the bending radii because otherwise it won't change much."

When I create a sheet metal part, the dimension of the unfolded changes as I change the coeff of the K factor.

I modify the K-factor of the sheet metal function and I check that the ply functions follow the parameters.

Thank you very much your solution allows me to modify the rating according to the K factor.
