Lumber sections (inches: width × height)

These map 1:1 to the SECTIONS dict in pole_barn.py. Width = the face you want oriented per the member rule; height = thickness.

Toggle these off/on and watch the 3D view — once everything lines up, hit Export for backend and paste the result into pole_barn.py.

Camera / view depth

View depth — far plane (ft)

Near plane

If the shop/building gets cut off when you zoom out or hit Fit view, raise the view depth.

Member axis transforms (in / °)

Object type

Move X (in)

Move Y (in)

Move Z (in)

Rot X (°)

Rot Y (°)

Rot Z (°)

Pick a member type, then translate/rotate it around its own center. Rotations are applied as a local YXZ gizmo.

Roof purlin slope (fixes inset/rotation)

Auto-rotate purlins to match roof slope

Eave overhang nudge (in)

With auto-slope on, purlins tip to lie parallel to the roof plane. The nudge pushes them out past the posts to fix "side purlins inset too far".
