Using ilogic to access the inventor api we created a custom iproperty and pushed the k factor from the current sheet metal style through to it. Most cad systems that have sheet metal design tools will allow you to input a k factor that the software uses to calculate the unfolding to give an accurate blank or flat pattern. This is not as easy as pulling a parameter through to the drawing as the k factor value is embedded in the sheet metal style of the component. Owner of ycg inc.

The k factors mentioned are to suit our own press and tools of course. So for a very large radius bend where the neutral axis lies right in the center of the material the k factor would be exactly 0 5 or half the thickness. Sheet metal k factor. We produce a lot of sheet metal work using invento and use 0 2732 for below 3mm sheet and 0 3365 for 3mm and above using ilogic we automatically set the k factor depending on the thk of material so we don t forget to adjust it each time.
