Building bump-outs for dormers.


Recommended Posts

Hello Everyone,

Trying to created a "dormer bump-outs" with no luck. I have 2nd. floor with roof starting at 5 feet and then continuing on to 8 ' at 12/12 pitch. When I bump out the 2nd. floor portion of the wall for the window, the wall is going to its full height, as it should , then I place the window in the bump out that is is higher than the existing roof plane. I created a manual roof planes on the top of the bump out, but then I can't close little space between the new "dormer" roof planes and  the lower main roof plane. In essence, I want a knew wall from the new small roof place to the main - existing lower roof plane....See attached a picture of examples...Any ideas how to solve this....?

Answers often depend on which title (Suite, Pro etc) and version (2018, 2019 etc) you are using.


You can help everyone by adding that info to your signature (see below for how to turn them on) by clicking on your user name at the top right of the page, click Account Settings, then Signature on the left.


Doing so makes it always available, and keeps others from having to hunt for it.


And, turn on signature display too.
