Canopies & Roof Extensions

(Revised: 05/08/13)

The Canopy and Roof Extension screen is used to locate and define At Eave or Below Eave Canopies.
On Endwalls (Wall 1 & Wall 3) the Roof Extension option will be available.

This feature has automated flexibility enabling you to modify the size of the shape or the frame locations without losing the canopy data.

Canopies can be located full span or partial span, dimensioned from the edge of a wall or from any existing frame line.

Additional adjustments for extending canopies into roof extensions and skewing the corner options are available.

Canopies & Roof Extensions:

This is dimensioned to the out of the steel structure, not to the out of trim or flashing.

This check box sets the overall length of the canopy or roof extension to the entire length of the wall.

Canopy Adjustments are enabled.

Select where the Start of the canopy is located.

If the Start of the canopy is at a Frame Line or an End Post, Frame Locations must be defined prior to defining the Canopy Start.
