Custom curtain wall panel not adjusting to triangular curtain wall for roof

[Lib125]

Hello, I made a custom curtain wall panel for my school project and I am trying to get it to fit onto my curtain wall that has a triangular boundary to fit into my roof. However, the panel remains rectangular, leaving a part of it jutting out of the roof. 

I have tried boolean operations to use morphs and try to subtract the extra part of the panel with no success. I have also tried solid element operations to try to use morphs to try and subtract the extra part of the panel with no success too. 

Does anyone know how to go about this? I attached screenshots showing my process and also one showing how glass panels adjust to the boundary, but my custom panels don't.

Thank you!

I don't understand but the third photo looks like it removes the part outside rhe perimeter .

It looks like a SEO is performed.

Unfortunately custom panels do not follow the curtain wall boundary.

Sorry for the confusion, the third photo shows before doing solid element operation subtraction, then the 2nd shows the after showing how it didn't work. It looks like it removes it because it is a glass material.

Thank you for the reply Botonis.

You have to keep the two elements together for the SEO to be preserved.

Otherwise the part will reappear.

Put the SEO operator in another layer and turn the layer off.

This worked perfectly, thank you very much! 

Attached are the photos showing it worked.

There is another solution where you can SEO the panel with the boundary frame (grey profile)

which goes above the panel.

Just get into the curtain wall edit mode (the button when curtain wall is selected) and try SEO between those two with upward extrusion .

Without the need for extra elements like the morph.

Can you try cause I am not in my computer right now.
