Hi all,
I'm currently developing a model for the below detail which includes a metal panel angled off a window jamb.

So far I've attempted using a profile from the curtain wall (our windows are curtain walls in our office) and create the extrusion from there. It's essentially a large block as I can't layer the profile to match the wall build up as I need to keep it in one loop.

To get over this, I've created a detail component which can be seen on the plan view below.

This workflow is okay if all of the angles and lengths all stay the same, however if I need to edit sizes it's a case of going into the profile then the detail component to suit. In addition all windows would need to be extended down from the sizes I have now and then change the mullion family to the new one where it is used.
Would there be any better way of doing this?
Thanks!
