AutoCAD Sedimentation Tank Slopes Program

General Program Information

Input Definitions

Inputs Needed to Call the Sedmintation 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.

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.
