I would like to create a cross gable roof of my structure where the roof ridges meet. How can I accomplish this task in Home Designer?
Creating a cross gable roof is easy to accomplish using the per-wall roof settings located in the Wall Specification dialog in conjunction with the Build Roof tool.
Now you can see that your gable ends have been created where you want them. However, it is clear that the 6" Pitch is not going to allow for the thinner portion of the structure to meet up with the wider portion's ridge height.
As you have already specified a gable end for this thinner part of your cross gable, you will need to increase the pitch for its side walls to allow it to meet at the center.
If you have Auto Rebuild Roofs checked in the Build Roof dialog, you will notice these changes take place as you go wall-by-wall through the plan.
If you do not have Auto Rebuild Roofs checked, then you will need to return to the Build Roof dialog to rebuild your roof after changing all of the indicated walls.
With a basic understanding of these principles, you can apply them to your own designs. Keep in mind that you may need to adjust the Pitch of the cross gables more than once to get their ridges to align perfectly with the main roof ridge.
