Filling a ceiling plane or creating a room ceiling that is sloped in 3 directions.


Recommended Posts



I am trying to figure out how to best replicate this design within Home Designer Pro (2021):





So far, I was able to use ceiling planes to create what is basically the "bottom" of the ceiling:




But I have no idea how to get it to be solid (e.g. not seeing the attic) so that it looks as close to what it would in real life as possible. I am not sure if there's an easier way to do this outside of ceiling planes but any help/suggestions would be greatly appreciated.

I see you said Pro 2021




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.






Many questions have been asked and answered. The Home Designer website is a good place to start your search.

It looks like you need to lower the roof, and it's not real clear what you are trying to accomplish.


These 3 roof planes should probably be the underside of your roof.

Thanks Solver -- The thing I am struggling with is how to make that the underside of the roof. I have the roofline currently matching it but I don't know how to bring the wall height on that one side down. Do I have to make each section of that room a different room and then change the ceiling height or something?

Thank you, yes that's exactly what I am looking for -- just not exactly sure how to drop the roof planes in a single section of the room. Currently if I try to lower the roof plane of the gable, it ends up lowering the roof of the entire room. Below is what the automatic roofing is currently drawing. 



I am assuming I need to somehow split the room so that the first few feet near the front window can be lowered without impacting the rest of the room. Just not really sure how to do that - I have never really done manual roof-lines before and not sure if that's what I need to do or if there's another way.

You are giving us a keyhole view of the problem.

Is this an existing structure? If so pictures of it, inside and out would help.

Using the manual roof tools is often easier than trying to get the automatic roof to build correctly.

It's a to be constructed structure, so I only have the construction documents but here are the portions of the construction doc related to this room:

Thanks Eric - after fooling with manual roofing all day was able to figure out how to get this room's roof to work inside and outside - but just have one small issue where the interior wall is exposed on the outside at a slant (left corner of picture) but it's also on the inside (so I can't switch it to an exterior wall). I know with Pony walls you can make it half and half but I am not quite sure how to get it so the exterior wall is only for the portion that is visible on this slant. I am not quite sure what to even search for on how to resolve this issue.
