No appropriate roof plane is adjacent to the section starting...

Recommended Posts

I'm trying to replace an old rotten deck cover with a proper roofed patio cover using https://www.homedesignersoftware.com/support/article/KB-01086/creating-an-attached-porch.html

 

The three outside rails connect up as expected and with some careful adjustment I can butt the right hand rail up against the existing outer wall of the house. However when I add the roof according to the instructions I get the split roof effect shown in the screen shot along with the error message:

 

"No appropriate roof plane is adjacent to the section starting up from this kneewall. Need a lower roof plane whose high portion ends at the kneewall with which to match levels."

 

I'm trying to play with the different Hip wall / Gable Wall setting for the front rail, which seems to be the component that is having the problem, based on the circle being drawn under the error message but I'm clearly missing something here.

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.

I Apologize I thought I had done the signature thing (probably did not turn it on).

Not sure where you would use a kneewall. 

 

Is the shape you show correct?

 

You can attach the plan file -- close Suite first and zip.

Did you change the roof overhang on the wall?

I found a work around that will suit my immediate purpose (need a screen shot for my HOA Architectural Approval Form in order to progress).

 

By keeping the left and right (Gable End Wall) rails well inside the patio area the roof gets displayed in a reasonable manner, although the error dialogs are still displayed. Also the ceiling edges are well inside the roof overhang, which does not gel with the front porch which has the ceiling edge flush with the house wall with just a outer wood beam supporting the outer edge of curved Spanish tiles (probably something I can do in the Build -> Roof dialog around overhangs).

 

The plan is attached if anyone want's to take a look at where these error dialogs are coming from (I've left the rails visible for now as it's easier to see where things are lining up, but obviously these would go invisible and a couple of front support posts would be required (as per the initial picture above).

 

I'll admit while I love this software I have not used it in many years (I just checked and it was 2012 when I spent many hours with a measuring tape and evenings creating the full house plan, in order to get HOA approval for a front patio upgrade) so I'm really rusty.
