How to build Shed Dormer?

[Doug_Morrison]

Using HD Pro 2024 and struggling to build this shed dormer on back of house. Here’s what it’s supposed to look like.

Here’s where I’m at in HD, and software won’t let me build a roof over this room?

I get this error and software locks up if I hit OK.

 

I.ve attached the plan file if that helps. Any help building this shed dormer would be appreciated. Thanks in advance!

Doug, here's what I looked at, refer to the images.

1. I turned on the Auto Rebuild Roofs

2. On floor 2, I extended your wall across, so the roof would build symmetrically

3. Placed a shed dormer and adjusted the windows.  It's a floating dormer; if you want a structural dormer, which seems likely here, you need to draw walls to connect it (refer to the help system if you need)
