General Information

Input Definitions

Inputs Needed to Call the Sludge Pipe Function

• sludgepipe_origin - a 3 by 1 matrix with x,y,z positions corresponding to the point where the manifold will be drawn
• sludepipe_inr - the radius of the inner cylinder
• sludgepipe_outr - the radius of the outer cylinder
• rad_hole - the radius of the orifice hole
• tank_length - the length of the tank
• orifice_dist - the distance between successive orifices

Pipe Database Functions

• innerD()
• outerradius()
• EN_PipeSpec

Note: zc corresponds to the zoom constant used within AutoCAD and created in the basics file that is referenced by the pipe program.

Technical Program Outline

Note: All coordinates are referenced in top view in the program unless otherwise specified

pipe1 - draws a pipe (from the pipe program) with no zoom

zoom_win - zooms on a window space

cylinder3 - is to draw a cylinder for orifice purpose

viewrightside - change view to viewrightside

array1 - draw starting at point p1, n1 -- as many rows as the tank length/orifice dist, n2 - 1 and provide orifice distance as the next draw point for the cylinder

subtract2 - subtract unneeded portion of the cylinders
