Merge Planes

Merge-Planes

This command forms one roof plane out of two roof planes that are in the same plane in space that is, coplanar.

After you select the command, you then select the two roof planes you wish to merge. As long as the two planes are parallel, coplanar and share a common edge either fully or partially, a new roof plane will be formed. If connected lines are collinear and are the same type and are connected to the same planes, those lines are merged also.

Consider the following diagrams where there are 2 gable roofs butted up to each other. You can see in the “before” image that the roof planes are separate planes. For a tile roof, this may not be an issue, but for a metal roof, you want the bottom plane to be continuous. Using the Merge-Planes command, you can select plane d1 and plane d2 and turn them into one plane. You can see the hatch pattern in the “after” image is continuous.

The isometric image below, gives you a better idea as to what the roof is doing.
