Rafter punching

Drag an orange hole to move it. Drag a purlin to slide it along the rafter. Holes are drawn to scale: M10 bolt, Ø 11 mm hole, same for rafter, column and brace.

Front view

Legs, frame spacing and purlin jointers. Drag a jointer (or a leg with custom spacing); the 3D, bill and cutting list follow.

3D view

New

The current design in 3D, built from the same sizes as the drawing, BOM and cutting plan, with real C-lip, strut and pipe sections. Drag to turn, scroll or pinch to zoom.

Sun, row gap & area

Uses the site state, season and facing from Target tilt. Turn on Real sun above to see the sun path and shadows in 3D; save pictures with the 3D image buttons.

Area required

Existing / saved models

Pick a saved model to load its sizes, or set orientation, rows, panels per row and purlins under the drawing: matching saved models are suggested there.

Default 6 in (0.5 ft). Raise it for ground mounts near soil, water or plants. The target-tilt box above then also gives the lowest column heights that keep this gap.

    Assumes both columns stand on one level and heights are measured from that level to the rafter hole centre. Panel and purlin rules are working rules for layout; confirm clamp zones, hole spacing and fixing with the panel datasheet. This is a layout aid, not a structural or fabrication approval.
