Trailer Loader Pro
Trailer
Preset dimensions are nominal starting points only. Confirm against the actual trailer or container before committing a load plan.
Shelving (Fixtures)
Levels = how many individually assignable shelves this one unit has, stacked top to bottom. Click a unit (in the 3D view or in Trailer Fixtures below) to select it, then adjust its size or position here and click Update Shelf -- or just drag it in the 3D view to reposition it directly. Any cargo assigned to a unit follows it. Units are fixtures, not cargo: they don't count toward weight, value or floor-use stats.
Cargo Item
For a part that changes size from one end to the other. Wid and Hgt shrink or grow from the nose end to the tail end; Len differs between the left-wall side and the right-wall side. Leave a box blank to keep that dimension uniform. Collision and floor space use the larger end (floor % uses the average); the manifest and PDF show both sizes.
Loads the real part shape in place of a plain box, scaled to fit the Len/Wid/Hgt above. Export as .glb (binary glTF) from your 3D/CAD/scanning app.
Selection
Drag a pallet to place it. Keyboard: R rotates, D duplicates, L locks/unlocks, Delete removes the selection. Use [ and ] to hide or show the side panels. A locked item (cargo or shelving unit) can't be dragged, rotated or deleted until unlocked.
