Oversize the depth of "splay" in windows?

[AlexV]

Is it possible to control the depth where the reveal starts? so that I an have simmilar wall profiles with different frame thickness?

All window objects start their reveal att the back of the frame- there is an option for a reveal that extends sideways from the frame but not in depth.

Using SEO for this is an option but wanted to check if there is a built-in way.
