Bay-Window

The Bay-Window command lets you insert a bay window onto an existing roof. After selecting the eave line onto which the bay window is placed, the Bay Window Dialog box is displayed.

Distance along eave
This is the distance from the end of the selected eave to the start of the bay window.

Out step length
This is the length of the initial projection away from the eave.

Face length
This is the length of the face parallel to the eave.

Skew length
This is the length of the side connecting the step with the face.

Angle
This is the angle which the skew lines are to the eave (0-90 degrees).

Pitch
This is the pitch of the face plane. The side planes are then calculated to suit.

Zero length ridge
This is either yes or no. If No, then the pitch of the face plane is calculated to intersect the main roof plane such that no ridge is created.
