Canopy Layout (Diagram)

Mounting / support type

Drives the live drawing. # Sections = roof-panel divisions (interior intermediate frames + gutter-fascia edges). # Support arms = angled wall brackets, independent of sections. Wall anchors = arms × bolts/bracket.

Heights & Loads

Self weight / dead load (psf)Aluminum is light (~2.5–5 psf). Don't pad it — higher dead reduces net uplift (unconservative for arms/anchors).

Strut / Support Arm

Arm reaction is derived from canopy area ÷ # support arms (each arm carries ½ the canopy at 2 arms). Enter arm length & angle for geometry/buckling.

Custom / EMS Section Properties

Used only when a member's Section is an EMS extrusion or "Custom". EMS open fascia/pan shapes aren't auto-computed — enter A (in²), I (in⁴, strong axis), S (in³) from the EMS engineering sheet. EMS extrusions are 6063-T6: set Fty/Fcy = 25 ksi.
