Array format

Array[X,Y,Z] is a 3-dimensional array *of Objects* with height X, width Y, and depth Z. The type of data contained within the Object varies by the Instance ID of the file.

  • Functions:
    • 1. To store arrays of the height values of grid points in singles. And, the layer/story/level of grid point is presumed probably based on values of W, H and layer/story/level probably partly dependent on the same 3D array instance file.
    • 2. Every standard level height is 16-click-high/16-step-high, and it has a value of 3 in singles. In other words, each click (in terms of elevation tools)/step (in terms of modular stairs) is 0.1875 in singles.
    • 3. Negative value can exist in singles and later values can be smaller than the previous values for every layer/story/level as V!ND!CARE's <4-click wall tutorial suggests.
    • 4. if there's a swim pool, the underground layer of grid points will be placed earlier than the ground lot origin.
