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 Roof panel of the Wall Specification dialog in conjunction with the Build Roof tool.
Now that you have defined your Full Gable Walls, to create a gable end over the selected walls, build the roof to see the results to this point.
Now you can see that your gable ends have been created where you want them, however, it is clear that the default pitch of 6/12 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 from the default 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 in your plan (*Auto Rebuild Roofs not available in Home Designer Essentials.)
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.
