Section cut - cleaning up of junctions.

[Wayne Blythe]

I have made a wall and a flat roof. I then used the roof tool to create the mansard section. On the screen grab you can see the all the lines meeting, is there a way to clean this up? So it just shows up as one grey fluid fill and just outlined on the outside and inside? 

Operating system used: Mac Apple Silicon 26.2

There's a few possible ways to achieve this, maybe the easiest being Solid Element Operations, see Solid Element Operations. You'll need to use the same Building Material in all the joining elements.

Are you able to walk me through an example of how you would do it?

Is this a Composite Structure? It would be good if you could show a screenshot that shows the Composite Structure as that can also influence the method used, since you would want to individual skins to be realistic after connecting that Wall and Roof.

By the way, you could model this whole geometry using a single Extruded Shell (Wall, Slanted Roof, Flat Roof portion as a single geometry). Check the Help files for instructions.

You can also try to use the "Merge Elements" command.
