Roof Over-Frame Connect Issue

[RiverstoneMT]

Hello,

 

I'm using X16, and I keep running into a gable over frame issue. See Attached picture. 

Every time i create a new section of building with a different ceiling height, the auto roof creates two different planes, instead of just connecting the roof into the existing plane. I understand that the ridge may be higher in some situations, but in the past, the program just created a "broken hip" at the ridge. This has been happening since i switched to x16. Even when the new ridge is lower, it still creates what is shown in the picture.

 

I've attached the plan file too. 

 

I'm sure its something simple, but for some reason i cant seem to figure it out. Damuth Plan.plan

 

Specifically on this project, the blue section is going to be an addition to the existing home.

 

Thanks in advance

It seems like the auto roof should be able to handle this.  Your plan is no longer available to play with though.

Did you remove the zipped plan?

Try this:

 

The saddle is taking its height information from the ceiling height of the main room, which is lower than the addition.

 

To fix this with Auto Roofs, create a small room under the saddle that is the same ceiling height as the room addition.

 

Display Roof Planes and draw Room Divider walls directly aligned with the saddle:

 

Open the little room and set its ceiling height to match the addition:

 

 

This may cause undesired results with the interior of the building that will need to be addressed, like adding a manually drawn ceiling plane in the overall room, but this fixes the roof.

 

It's interesting that even though the Room Divider walls no longer align with the saddle, it still works. There may be a better solution...?

As far as I know the behavior you're seeing isn't new; that's always how auto roofs would handle that condition from what I remember. I went back to X12, which is the oldest version I have on this machine to test it and got the same results as you. Maybe someone else has a different answer...
