Opening endcap. Revit Help

[arqyt]

I do it modifying the window/door family, replacing the hole with void mass

But in revit help, this option appears to solve the insertion of door/window in a wall. But I don´t locate how to adjust the layers to locate opening insertion in walls, like can see in the help image. The help text is not clear on the process.

Any idea?

I explain better.

How can i do that modify of the profile of the wall endcap?

Ok, I've solved the dilemma and share it.
Changing the cut-hole wall, for a void-mass, the enveloping layers fit this profile determined by this void-mass.
