General Program Information

Unknown macro: {float}


Free Rotation Used



Input Definitions

Inputs Needed to Call the Inlet Slope Function

origin - A 3*1 matrix with x,y,z positions corresponding to the point where the inlet slope will be drawn.
Length - length of the slopes, generally the width of the sedimentation tank
Width - width of the slopes, generally the width of the sedimentation tank
lorifice - length of the opening that will allow inlet flow
horifice - height of the opening that will allow inlet flow
thick - thickness of the slopes
n - number of orifices and sections, one section contains one orifice
bigslope - slope of the inlet in degrees

Inputs Defined within the Inlet Slope Function

dim =
*x: Length/2
*y: thick
*z: (Width/2)/cos(bigslope)

boxdim = origin + dim

orificeorigin =
*x: origin0 + dim0/2 - 1orifice/2
*y: origin1
*z: origin2

orificedim =
*x: origin0 + dim0/2 + 1orifice/2
*y: origin1 + dim1
*z: origin2 + horifice

mirrorpoint1 =
*x: origin0
*y: origin1

mirrorpoint2 =
*x: origin0 + zc
*y: origin1

nrow = 1

ncol = n

dist =Length/n

win1 =
*x: origin0 - zc
*y: origin1 - zc
*z: origin2 - zc

win2 =
*x: origin0 + dim0 - zc
*y: origin1 + dim1 - zc
*z: origin2 + dim2 - zc

Note: zc corresponds to the zoom constant used within AutoCAD, defined by the basics file.

Technical Program Outline

Unknown macro: {float}


Top View

viewtop - sets the workspace so that the user is viewing the top of the object.

viewtop <-- viewtop
zoomwin- zooms on a window space directly around where the inlet slope is to be drawn.

zoomwin <--zoom win(win1, win2)

win1 =
*x: origin0 - zc
*y: origin1 - zc
*z: origin2 - zc

win2 =
*x: origin0 + dim0 - zc
*y: origin1 + dim1 - zc
*z: origin2 + dim2 - zc

Unknown macro: {float}

box1 - draws a box
box1 <-- box(origin, boxdim)

origin = origin

boxdim = origin + dim

Unknown macro: {float}

box2 - draws a box that will be subtracted to become the orifice
box2 <-- box(orificeorigin, orificedim)

orificeorigin =
*x: origin0 + dim0/2 - 1orifice/2
*y: origin1
*z: origin2

orificedim =
*x: origin0 + dim0/2 + 1orifice/2
*y: origin1 + dim1
*z: origin2 + horifice

Unknown macro: {float}


Southeast Isometric View, Before subtract1

Southeast Isometric View, After subtract1

subtract1 - subtracts box2 to create an orifice, using the origin to select box1 as the object to be subtracted from, and using orificeorigin to select box2 as the object to be subtracted

subtract1 <-- subtractD(origin, orificeorigin)

origin = origin

orificeorigin =
*x: origin0 + dim0/2 - 1orifice/2
*y: origin1
*z: origin2

Unknown macro: {float}


Southeast Isometric View, Before array
Unable to render embedded object: File (6.bmp) not found.
Southeast Isometric View, After array

array - replicates the piece n times, with a spacing of dist between each

array <-- arrayB(origin, nrow, ncol, dist)

origin = origin

nrow = 1

ncol = n

dist =Length/n



Unknown macro: {float}


Southeast Isometric View

union - Unites all the individual components of the inlet slope to act as a single unit

union <-- unionallA

Unknown macro: {float}


Free Rotation used to show rotation

rotate - rotates the inlet slope about the x-axis, with the origin as the pivot, 45 degrees. Information about the rotate3d function can be found in the [Basics Help Page].

rotate <-- rotate3d(origin, origin, "x", 45)

Unknown macro: {float}


Top View, Before mirror

Top View, After mirror

Free Rotation used

mirror - replicates the original inlet slope drawn by selecting the original inlet slope using the origin, then reflecting it over a mirror line created using to give the slope and direction of the mirror line.

mirror <-- mirror(origin, mirrorpoint1, mirrorpoint2)

origin = origin

mirrorpoint1 =
*x: origin0
*y: origin1

mirrorpoint2 =
*x: origin0 + zc
*y: origin1
