cylinder1 - Draws the larger of the two cylinders needed to create a pipe. The cylinder has pipe_outr as the radius. From topview, the cylinder draws up towards the viewer with the pipe origin at the bottom base.

cylinder1 <-- cylinder(origin,pipe_inroutr,pipe_length)

origin =

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

pipe_outr : outerradius(2*pipe_inr

pipe_length : pipe_length

cylinder2 - Draws the smaller of the two cylinders needed to create the pipe. The cylinder has pipe_inr as the radius. From topview, the cylinder draws up towards the viewer with the pipe origin at the bottom base. This inner cylinder will then be subtracted to creat the hollow pipe

cylinder2 <-- cylinder(origin,pipe_inr,pipe_length)

origin =

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

pipe_inr : pipe_inr

pipe_length : pipe_length

subtract1 - In order to create the hollow pipe, the inner cylinder must be subtracted from the outer cylinder. The subtract function selects p2, on the edge of the inner cylinder, to select the inner cylinder as the piece to be subtracted. The subtract function selects p3, on the edge of the outer cylinder, to select the outer cylinder to subtract from.

subtract <-- subtract(p2,p3)

p2 =

• x : origin₀ + outerradius(2*pipe_inr)
• y : origin₁
• z : origin₂

p3 =

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