AutoCAD Sedimentation Tank Slopes Program

General Program Information

Input Definitions

Inputs Needed to Call the Sedimentation Tank Slope Function

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

Notes

• All coordinates correspond to a top view.
• 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.

Inputs Defined within the Slope Function
origin =

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

p2 =

• x : origin₀ + tank_dim1/2
• y : origin₁
• z : origin₂

tank_length = tank_dim0

slope_width = tank_dim1/2

slope_height = (tank_dim1/2)/tan(ϕ)

Technical Program Outline

zoom_win- 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).

pline1 - creates a one-dimensional triangle.

Note: picture about has been rotated to show extrution.

extrude1 - extrudes the triangle creating a three-dimensional wedge.

rotate3d1 - rotates the wedge 90 degrees around the x axis.

rotate3d2 - rotates the wedge 270 degrees around the z axis. The wedge is now aligned with the lower right hand corner of the sedimentation tank.

mirror3d1 - creates a mirror image of the wedge.
