Dormer roof joining issue

Recommended Posts

First off, thanks to the contributors on this site.  After some diligent forum searching I managed to solve the majority of my dormer issues. 


However, I'm still having an issue with getting the roof planes on the gable side to join properly.  I've recreated my issue in simplified plan attached.  As shown, the dormer roof planes extend to the edges of the primary roof planes and I thought I should be able to just use a join function to merge a dormer plane to its corresponding primary plan, but whenever I do I get the "Cannot move these roof edges without making adjacent edges cross one another or making one of them zero length" warning.  These dormers happen to be symmetric so I can successfully join the two dormer planes at the ridge line, but it creates some strange overlap artifacts as shown in the picture.


Any help would be appreciated.

I do not have time to repair right now, but your roofs are not set up same. Pitch/ baseline/fascia top must be same on both roof planes for them to join seamlessly. Examples: roof plane was 11 1/16" roof pitch, baselines are of too, get all these settings correct on each roof plane and I think all will be well. Be back at dsk this afternoon

Thanks for the response Shane and I see what you mean about the attributes not lining up. Not sure what happened on the pitch and such, but in theory, could the dormer and the primary roof have the same baseline since one is set on the dormer wall and one on the side wall?

So I've gone in an corrected the slight differences in the ridge lines by recreating the roof planes.  All primary roof planes have the same baseline, pitch, and ridge top, the two dormers have the same baseline, pitch, and ridge top, and the dormers and primary roof planes have the same ridge top.  However I still have the same issue as above (as well as another visual artifact I've pointed out in my _1 picture below.


Is there a solution to these imperfections?  Are they indicative of some actually issues in the way I connected things or are they purely visual?


In my mind, it seems like I should be able to join the dormer plane with the primary roof plane by selecting the dormer, pressing 2, and clicking on the primary plane like I've shown in my _2 picture.  But that just generates the zero length error I cited above.

      The red arrows point to the problem area.
      The outside wall and interior wall at the closet intersect with the valley where the two roof planes intersect.
      The interior of the room creates an attic wall (with exterior siding) above the closet (NOTE: Ceiling was removed to get image)
      The plan view shows where the roof planes intersect at the valley. I have the same problem on the other side of the house because it is symmetrical.
      The plan is too large (65MB) but here is the model (https://3d-viewer.chiefarchitect.com/go?share=543146417714334).
      Any suggestion on how to fix this would be greatly appreciated.

      How do I get the siding to show up on in the gable? See attached pictures.. Also, what is the best way to align the eyebrows along the front?
      Thanks in advanced..

      How do I get the gable roof planes to stop automatically adding these eave ridges or whatever they may be onto the planes?
      See attached picture.....

      This bathroom is upstairs, tucked into a dormer. You can see the adjacent roofs in the mirror reflections.
      Reflections like these can be controlled in the Material Properties, and displayed using camera specifications. PBR views like this one do a good job representing reflections in mirrors, and also reflections on shiny surfaces like counters, porcelain, and even metal. Other benefits of this rendering technique are high quality shadows and lighting, all combined with real-time rendering. This means you can navigation your scenes in front of a client or home owner and it will look as good from each angle.

      You'll notice that floor plan Option 3 and Option 4 for the Paradise Rises project are quite similar. Both are a story and a half with matching structural walls and feature livable attic space. The attic in Option 3 has been left mostly unfinished. This creates an opportunity for a home owner in Paradise, CA, to rebuild a livable space for themselves with cost savings by not immediately finishing the upstairs. Once they are prepared to complete the project, residents to can choose to wrap it up on their own accord.
      Review the full design set to see how the attic spaces differ between architectural styles due to the location and placement of dormers.
