Question

In Sheet metal design, for folding we need to set the K factor value. We had to change Creo's default K factor value. Every time we had to change the value again and again. Is there any config option for setting the K factor value as default?

Hi,

create sheetmetal template model and use it as start model.

Isn't there any other option like changing the default setting value?

I think PTC uses the Y-factor for the option. Y factor = K factor * (pi/2)

The config option for the Y factor is:

INITIAL_BEND_Y_FACTOR [VALUE]

Warning:

If you use a start part for sheet metal, whatever was set on that part at the time it was created will be the value.

If you convert to your sheet metal parts from solid parts, your initial Y factor value will be the one in your config.pro

    Setting your company's Y-factor in a sheet metal start part template is the best method for getting it set right.

    Using the config.pro is icing on the cake and as Steve mentioned is needed if you convert your parts from a solid to a sheet metal part.

    We had to change our start sheet metal part where I used to work to get the bends to match what we were manufacturing. We did have 18 years of using a K-factor value in Unigraphics that worked, so when we switched to Pro/E, we just converted the UG K-factor to a Y-factor.
