Input Definitions

Inputs Needed to Call the Sedimentation Tank Slopes Function

origin - a 3 by 1 matrix with x,y,z positions corresponding to the point where the pipe will be drawn
tankdim - a 3 by 1 matrix with x,y,z positions specifying the inside dimensions of the sedimentation tank
angle - angle specifying the slope of the sedimentation tank walls

Inputs Defined within the Sedimentation Tank Slopes Function

origin =

  • x : origin0
  • y : origin1
  • z : origin2

mirrorpoint =

  • x : origin0
  • y : origin1 + tank.dim1/2
  • z : origin2

tanklength = tank.dim0

slopewidth = tank.dim1/2

slopeheight = (tank.dim1*tan(angle))/2

win1 =

  • x = origin0 - tank.dim1/2
  • y = origin1
  • z = origin2

win2 =

  • x = origin0
  • y = origin1 + (tank.dim1*tan(angle))/2
  • z = origin2

Note: the slope function draws the sloped sides in one sedimentation tank. The sedtank function copies the one tank as many times as needed in the design.

Technical Program Outline

zoomwin - zooms on a window space directly around where the slope is to be drawn (as shown above - actual window size relative to slope that is to be drawn).
zoom1 <-- zoomwin(win1,win2)

win1 =

  • x = origin0 - tank.dim1/2
  • y = origin1
  • z = origin2

win2 =

  • x = origin0
  • y = origin1 + (tank.dim1*tan(angle))/2
  • z = origin2

pline1 - creates a two-dimensional triangle.
pline1 <-- pline(pline1,pline2,pline3)

pline1 =

  • x = origin0
  • y = origin1
  • z = origin2

pline2 =

  • x = origin0
  • y = origin1

pline3 =

  • x = origin0 - slopewidth
  • y = origin1

extrude1 - extrudes the triangle creating a three-dimensional wedge.
extrude1 <-- extrude(origin,tanklength)

origin =

  • x : origin0
  • y : origin1
  • z : origin2

tanklength = tank.dim0

rotate3d1 - rotates the wedge 90 degrees around the x axis, using the origin to select the wedge, and the origin to specify where on the x axis to rotate.
rotate3d <-- rotate3d(origin,origin,"x",90)

origin =

  • x : origin0
  • y : origin1
  • z : origin2

"x" - specifies which axis to rotate in

90 - specifies how many degrees to rotate

rotate3d2 - rotates the wedge 270 degrees around the z axis, using the origin to select the wedge, and the origin to specify where on the z axis to rotate. The wedge is now aligned with the lower right hand corner of the sedimentation tank.
rotate3d2 <-- rotate3d(origin,origin,"z",270)

origin =

  • x : origin0
  • y : origin1
  • z : origin2

"z" - specifies which axis to rotate in

270 - specifies how many degrees to rotate

mirror3d1 - creates a mirror image of the wedge, using the origin to select the original wedge, and using the mirrorpoint to select the point to mirror the wedge about.

mirror3d1 <-- mirror3d(origin,mirrorpoint)

origin =

  • x : origin0
  • y : origin1
  • z : origin2

mirrorpoint =

  • x : origin0
  • y : origin1 + tank.dim1/2
  • z : origin2

unionall - unites the two separate wedges to act as one unit

unionall <-- unionallA
