Decide whether a final arrangement can actually be loaded
A coordinate drawing shows where rectangles finish, not the path used to reach those positions. A loader needs access from the opening, a workable insertion sequence, and space for the handling process. None follows automatically from nonoverlapping final coordinates. Review the proposal as a final-position geometry result, then ask the operation to verify how each object arrives there.
The current floor engine arranges identical axis-aligned rectangles inside the entered interior floor. It validates boundaries, separations, and allowed footprint rotation. It does not animate pallets through a door or model a lift truck, forks, turning radius, temporary staging position, or a trajectory around objects already placed. This guide uses a hypothetical floor to make the difference concrete.
Inspect a four-position rectangle that fills the floor
On a 2400 by 1600 mm floor, four 1200 by 800 mm footprints fit exactly at zero gap and wall clearance. One coordinate arrangement starts at (0,0), (0,800), (1200,0), and (1200,800). Every rectangle is inside the boundary and their interiors do not overlap. Four case areas equal the entire floor area, so the count is optimal for that model.
The full-area layout leaves no final corridor. That observation does not prove an impossible loading process, since objects might be placed from an opening in a feasible sequence. It also does not prove a possible one. The model supplies neither an insertion path nor the handling geometry needed to decide. A visual opening between rows should not be inferred when the coordinates show edges meeting.
| Input | A | B |
|---|---|---|
| Interior floor | 2400 by 1600 mm | 2400 by 1600 mm |
| Loaded footprint | 1200 by 800 mm | 1200 by 800 mm |
| Opening width | 900 mm | 700 mm |
| Returned final positions | 4 optimal | 4 optimal |
| Simple minimum-side width check | 800 is below 900 | 800 exceeds 700 |
The floor count ignores door width because it is a different geometric question. The separate simple doorway check can flag B without changing the interior arrangement. A's width comparison does not establish handling clearance, approach alignment, or turning access. The article makes no claim that a 900 mm opening is suitable for a real pallet-loading operation.
Reproduce the floor and simple opening checks
Open A with the wider hypothetical opening and B with the narrower opening. The edited dimensions define this fictional test, not a carrier specification.
The basic case preview gives a height-derived stack of five 250 mm layers above a 144 mm base, or 1394 mm. The simple door-height comparison uses that calculated stack. An actual measured load height should be checked separately if protection or a partial arrangement changes it. The floor geometry itself is two-dimensional and does not certify any stack.
Map the coordinate origin to the actual opening
The drawing's X and Y axes are dimensions of the floor rectangle. Coordinate (0,0) is not automatically a physical left doorway corner. Record which end of the real equipment corresponds to each drawing boundary. A sequence described as “load the far row first” is ambiguous until the opening and direction are located on that same drawing.
Ask the loading operation to identify the proposed first placement, how it reaches its location, and what access remains for the next placement. Repeat through the last object. This is a separate review using actual handling information, not an algorithm offered by the current tool. A marked sequence can accompany the geometric drawing, but it should be labelled as an independently reviewed process.
Do not mistake small gaps for handling routes
Changing the synthetic floor to a ten-millimetre gap between footprints yields two returned placements, best found, with area upper bound four. The count change reflects declared separations. A ten-millimetre strip is not automatically a usable handling corridor. Clearance dimensions must describe the operation's real requirement if they are intended to reserve access.
Nor should a gap be removed solely to restore a higher count when the process needs it. Compare the geometric effect explicitly, then retain the requirements that actually apply. The model cannot infer the missing route from the amount of unused area. A connected access path depends on its shape and location, not just a sum of empty square millimetres.
Review the last placement explicitly
A sequence that works for the first few objects may leave no access to the final proposed position. Ask the operation to identify the last placement and how it reaches that position with the earlier loads present. This targeted review is more informative than judging the full drawing's appearance or its area coverage.
Keep final-position and process evidence together
Coordinates establish a final placement candidate. A sequence review establishes a proposed way to load it. Door dimensions establish another boundary, and equipment dimensions must come from the assigned unit. None of these records should replace the others. If final load protrusions change, update both the floor positions and the access review rather than only its cube.
Loading-review handoff record
Fictional floor 2400 by 1600 mm; repeated footprint 1200 by 800; zero gap and clearance; allowed horizontal rotation; returned four positions optimal. Save the four coordinates and identify the actual opening on the same axes. Compare hypothetical widths 900 and 700 separately; minimum footprint side is 800. Height-derived preview 1394 mm is not a substitute for final measurement. The insertion path, equipment access, and reviewed loading sequence are still required.
Use the cube tool for a measured envelope and the methodology for the floor model's boundaries. A final drawing is a useful proposal when the handoff clearly states the separate access question it has not answered.
