Input Definitions

Inputs Needed to Call the Channel Function
channel_origin - a 3*1 matrix with x,y,z positions corresponding to the point where the channel will be drawn.
channel_dim - a 3*1 matrix with the x,y,z positions specifying the dimensions of the channel cutout.
t = - specifies the thickness of the channel walls.

Inputs Defined within the Channel Function

p1 =

• x : channel_origin0
• y : channel_origin1
• z : channel_origin2

p2 =

• x : channel_origin0 + channel_dim0
• y : channel_origin1 + channel_dim1
• z : channel_origin2 + channel_dim2

p3 =

• x : channel_origin0
• y : channel_origin1 - t
• z : channel_origin2 - t

p4 =

• x : channel_origin0 + channel_dim0
• y : channel_origin1 + channel_dim1 + t
• z : channel_origin2 channel_dim2

p5 =

• x : channel_origin0
• y : channel_origin1 + channel_dim1 + t

p6 =

• x : channel_origin0 - zc
• y : channel_origin1 - t - zc

p7 =

• x : channel_origin0 + channel_dim0 + zc
• y : channel_origin1 + channel_dim1 + t + zc

win1 =

• x : channel_origin0
• y : channel_origin1 - t
• z : channel_origin2

win2 =

• x : channel_origin0 + channel_dim0
• y : channel_origin1 + channel_dim1 + t
• z : channel_origin2

Technical Program Outline

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

zoom_win- zooms on a window space directly around where the channel is to be drawn (as shown above - actual window size relative to channel that is to be drawn).

box1 - creates a box that will serve as the channel cutout.

box2 - creates the outer box of the channel.

subtract1 - subtracts the inner box from the outer box to create a channel.
