If I increase the plate thickness of a foundation in RF‑/FOUNDATION Pro, the side length changes automatically.

How can I turn off this behavior?


If the dimensions of side lengths change after increasing the plate thickness, it is caused by the setting that the punching cone should be inside the foundation plate.

You can specify this behavior in the input windows by using the "Details" button. Here you can find the option "The defined punching cone in the distance lw is inside the foundation plate."

In order to freely define the geometry, unselect this option.
