Creating cornice on slat ceiling.

[mosmos]

Hi! I need to create a cornice for slat roof/ceiling (photo attached). 

My sloping ceiling is just a roof.  As much as I can do wall skirting, I can't cope with the slant. I was trying to attach it by beam tool in 3D but it looks weird and my custom profile stretches and changes size. Is there any automatic tool that helps me do that? Maybe attaching a beam by the heights of the wall rather than stories? 

Operating system used: Windows 11

Hi, Try using a railing with a custom profile. You can magic wand it to the roof edge and it will be associative. I do this all the time for roof flashings and gutters on industrial sheds

If I understand the question correctly; here are 3 options for getting a profiled beam to show the crown moulding in that condition. Sorry for the rambling/long vid:
