# Roof Design - New Corner

The "New Corner" function allows two lines of the roof surface's layout polygon to be connected to one another. All lines of the layout polygon for the same roof surface that lie between these lines will be deleted.

The two clicked lines are extended and connected to one another at a new corner. The roof-surface lines between them are deleted.

The two clicked lines are extended and connected to one another at a new corner. The roof-surface lines between them are deleted. In this case, the right-hand line did not need to be extended; it already had the appropriate length.

This function has no dialog box and no graphical translation. You simply select the two lines to be connected. The intermediate lines are then automatically deleted and the two selected lines are adjusted to the appropriate length.
