h3. Input Definitions
h5. Inputs needed to call the tank function
tank{~}origin~ \- a 3 by 1 matrix with x,y,z positions corresponding to the point where the tank will be drawn
tank{~}dim~ \- a 3 by 1 matrix with x,y,z positions corresponding to the length, width and height dimensions of the tank
* x: tank.dim{~}0~ = length
* y: tank.dim{~}1~ = width
* z: tank.dim{~}2~ = height
thick - the thickness of the wall of the tank
h5. Inputs defined with the tank function
p1=
* x : tank.origin{~}0~ \- tank.dim{~}0~
* y : tank.origin{~}1~ + tank.dim{~}1~
* z : tank.origin{~}2~ + tank.dim{~}2~
p2=
* x : tank.origin{~}0~ + thick
* y : tank.origin{~}1~ \- thick
* z : tank.origin{~}2~ \- thick
p3=
* x : tank.origin{~}0~ \- tank.dim{~}0~ \- thick
* y : tank.origin{~}1~ + tank.dim{~}1~ + thick
* z : tank.origin{~}2~ + tank.dim{~}2~
win1=
* x : tank.origin{~}0~ + thick + zc
* y : tank.origin{~}1~ \- thick - zc
* z : tank.origin{~}2~
win2=
* x : tank.origin{~}0~ \- tank.dim{~}0~ \- zc
* y : tank.origin{~}1~ + tank.dim{~}1~ + zc
* z : tank.origin{~}2~ + tank.dim{~}2~
*Note:* zc corresponds to a zoom constant used within Autocad. It is defined in the basics file.

*box2* \- Draws the larger of the two boxes to create the tank
box2 <-\- [boxA|AutoCAD Basics Box](p2,p3)
p2=
* x : tank.origin{~}0~ + thick
* y : tank.origin{~}1~ \- thick
* z : tank.origin{~}2~ \- thick
p3=
* x : tank.origin{~}0~ \- tank.dim{~}0~ \- thick
* y : tank.origin{~}1~ + tank.dim{~}1~ + thick
* z : tank.origin{~}2~ + tank.dim{~}2~
*subtract* \- In order to create the hollow box, the inner box must be subtracted from the outer box. The subtract function selects tank{~}origin~, on the edge of the inner box, to select the inner box as the piece to be subtracted. The subtract function then selects p2, on the edge of the outer box, to select the outer box to subtract from.
