I am struggling to understand the idea behind the Component Decal Height Keepout functionality.
In the attached design I have added a component height keepout area with a restriction of 250mils.
I would expect to be able to place R1 with its height of 100mils in the area beneath U1. But I cannot (with DRP ON).
It is the same in both Layout and Router.
I can understand I am prevented to place R2 because its height is 300mils.
Verify Design Check tells me that I have a Body to body clearance error.
But I thought the component decal height keepout should eliminate this?
In the manually added area at the bottom it works as expected.
I can place R3 without any problems, but I am prevented to place R4.
See attached files.
