Array[X,Y,Z] (see below)

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.

Count X (Width = [n1 x 10] + 1)

(number of grid point along the Width)

Count Y (Height = [n2 x 10] + 1)

(number of grid point along the Height)

DWORD

Count Z (number of array layers/levels/stories)

data storage format

Float (in singles)

• 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.

• Guesses: This may be a road pattern array or tiled grid array?
  • (Lot origin is the 'corner point' the shadow points at, and it is the origin a lot rotates at.)
    • 30 repeats of 20(0x00)-10(0x01) for a lot (Width=30 & Height=30; lot origin @ right & back corner; an empty 3x2 lot)
    • 30 repeats of 10(0x01)-20(0x00) for a lot (Width=30 & Height=30; lot origin @ left & front corner; an empty 3x2 lot)
    • 600(0x00)-300(0x01) for a lot (Width=30 & Height=30; lot origin @ left & back corner; an empty 3x2 lot)
    • 300(0x01)-600(0x00) for a lot (Width=30 & Height=30; lot origin @ right & front corner; an empty 3x2 lot)
    • 300(0x01)-900(0x00) for a lot (Width=40 & Height=30; lot origin @ right & front corner; an empty 3x3 lot)
    • 400(0x01)-1200(0x00) for a lot (Width=40 & Height=40; lot origin @ right & front corner; an empty 4x3 lot)
