Modeling profile around window reveal

[Anonymous]

Hi, does anyone have a tip on how to model the edge-profile around this window? See attached picture.
Tried to make a seo operator with the shell tool, but it was not successful. The problem is the arch on top..
Thanks,
Olav from Norway

You will need 3 separate shells.
An extuded shell for each side (the second side is just a mirrored copy of the first) and a revolved shell for the arch.
All using the same profile shape.
Join them together and group them for easy manipulation and then use that as your SEO.

This article also helped to understand more about the Shell Tool:

Just one remark:

With the solution mentioned in the article, you need to use the Connect > Trim Elements to Roof/Shell command, not SEO.
When you use SEO, the actual body of the Shell will be used for the operation, when the Connect type command is performed, the Trimming body of the Shell is used. This is why it is possible to create a solid body this way.
