Gable into adjacent wall

[funderburgh22]

I am trying to build the gable on the back of the garage, it should be centered on the gable in the front. I cannot figure out how to do this, I would like to leave auto build roofs on.

Most people prefer to manually edit roof planes to get what they want.  I lean towards using methods that keep "Auto Rebuild Roofs" turned on when I can.  I have started to use the "Gable Roof Line" tool on some of my projects.  If you are using auto-generated roof planes, you can place a "Gable Roof Line" using the "Gable Roof Line" tool. Line it up with your far front edge of the main wall layer and draw the line the same width as your front gable.  Then you can select line and move it to the back relative to the where you want the back gable.  Keep the line centered on your front gable.  Some users would like say this is not the best method of accomplishing what you are trying to accomplish.  I like it I can keep auto rebuild roofs turned on.

Here is a short video I generated where I manually edited the roof planes to create a rear gable on the back of my structure .  Rear gable is the same with as the front gable.  My video creation skills are not the best.

I wish that you could do this with auto roofs. BUT because having a gable there to match the front will create a dead valley when it intersects the opposing roof plane you will need to do it manually. Once you get the hang of it, it's simple.

 

Rene's video on this was super helpful.

Thank you for your response. I did try that tool, it did not work in this case but I could see it being useful.

I appreciate the video, that should work perfect. What is the best way to handle changes to the plan after auto rebuild is off? Ex. I turn auto rebuild off, then manually build a section, then modify an area that was built with auto rebuild on. How do I auto rebuild that section?

There is not really an easy way to auto rebuild a certain section of roof.  If you turn "Auto Rebuild Roofs" back on it is going delete your manually edited roof planes.   With "Auto Rebuild Roofs" turned off, you have to re-edit the roof planes everytime the footprint of your building changes.  I like to use the auto generated roof planes with auto rebuild roofs turned on, when I can.  Every wall has a "Roof" tab inside the "Wall Specification" dialog box.   Those settings along with the settings under the "Build Roof" dialog box the software uses to auto generate your roof.   Sometimes you can break a wall into two sections using the "Wall Break" and modify the "roof" tab settings for one of the segments.  This method allows you to keep "Auto Rebuild Roofs" turned on.  The one big downside is sometimes no matter what combination settings you adjust, the auto generated roof can't always give a person exactly what they need.  In these situations I just manually modify what is auto-generated to get what I need.  Many prefer to manually generate their roof planes right from the start.   Some users would say manually editing roof planes is easier than trying to adjust the different combinations roof settings to get what they need.
