Lean-to Issue

Recommended Posts



Pretty new to this game but starting to get in the swing of things (Note: Chief Architect - Home Designer Architectural 2021). 


I'm having a challenge with keeping the exterior finish above my lean-to. I think the photo is fairly self explanatory (I've made this specifically to show the issue). Ultimately I would like to put a line of narrow windows down this gap and have different pitches (4:12 on main and 3:12 on lean-tos).


Any suggestions here? Or when building lean-to's in this software in general.. I'm all ears!




Thank you kindly,

*** I see you said Architectural 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.

It's helpful to have your plan file to aid in troubleshooting -- so may ways of doing things and so many settings that may have been changed.


Close the program before attaching.

The plan builds with exterior siding showing as expected, in Architectural 2018.
The siding also shows as expected in Pro 2020.

However, in Pro 2021  (also HDA 2021 ) the siding does not show above the shed roof. 

Either something changed within the software, or it is a bug.

To fix this, you must reset the middle room ceiling back to default height.
Then build a blank 2nd floor (turn on floor reference), drawing 4 new walls over the walls of the middle room, and also align the walls.  Designate this room as 'open below',  decide on your ceiling height, and set the front and back wall roof as 'gable'.
