Define Bins

Example: -b 0:ft:1:5x5x5:1

Format: {id}:{dim_unit}:{quantity}:{size1}x{size2}x{size3}:{weight}

id: User identification code

dim_unit: The dimensional units. Recognized are ft, mm, cm and m which are all converted to inches. If not recognized, no conversion is done - the dimensions are assumed to be inches. If all your dimension use the same dimensional unit, then enter something unrecognized e.g. -

quantity: Number of these bins available. -1 indicates an infinite supply

size{n} : The dimensions of the bin

weight : The maximum weight of items the bin can hold. 0 indicates weight of items will be ignored. All weights in the same unit

Define Items

Example: -i 0:ft:0:1:1x1x1:1

Format: {id}:{dim_unit}:{constraint}:{quantity}:{size1}x{size2}x{size3}:{weight}

constraint = position_constraint + rotation_constraint

position constraint

0     :  anywhere
100   :  bottom only
200   :  top only

rotation constraint

0     :  Any
1     :  Length axis only
2     :  Width axis only
3     :  Height axis only
7     :  No rotation allowed

Output

The details of the pack are output in JSON ( see below ) and STL. The STL is intended to be viewed with a specialized STL-Viewer ( https://github.com/JamesBremner/STL-Viewer ) which animates the packing when the mousewheel is rotated.

Command Line: packit4me2 -b 0:ft:1:3x3 -i a:ft:0:4:1x2 -s b
