Split-Gable

Mod-Roof > Split Gable

This command attaches a gable roof to an existing gable end.

When you select the command, you are prompted to locate a ridge at the gable end. Then the Split defaults dialog box is displayed.  This provides parameters for you to set values for the new gable.

Fixed side
This toggles between Left and Right and assumes you are looking to the gable from the outside.  If you select left, then the left hand side of the new gable aligns with the left hand side of the existing gable and conversely for the right hand side.

Side for the new ridge
This toggles between Left and Right, again as viewed from the outside, looking in. If you select Left, then the ridge of the new gable will be to the left of the existing ridge and conversely for the right hand side.

Ridge offset
This is the amount the ridge will be offset.

Depth
This is the depth (length) of the new gable roof.

Tuck under
This is the depth that the offside of the new gable will project under the main roof.

After you click [OK], the new roof is drawn as well as merged with the existing roof.
