origin - is a 3*1 matrix with x,y,z positions corresponding to the point where the first lamella will be drawn.

...

lamina_i+4 - Enters the command "offset" into AutoCad. The offset function is used to move the selected object a specified distance from its original location.

lamina_i+5 - Enters The command 'stringit' turns the the variable "t" into AutoCada dimensionless number and cuts the number off after 5 decimal points. t represents the distance that the selected object is to be offset. The command 'stringit' turns the the variable "t" into a dimensionless number.

lamina_i+6 - Uses the 'point' function to turn the 3*1 matrix 'origin' into a text format that AutoCad can read.

...

lamina_i+8 - Uses the 'concat' function to create a character string out of a space, the AutoCad command "line," a space, the character string created in line₀, and a space. The purpose of the character string is to create a line in AutoCad between the two points specified in line₀.

lamina_i+9 - Uses the 'concat' function to create a character string out of a the AutoCad command "line," a space, the character string created in line₁ and a space. The purpose of the character string is to create a line in AutoCad between the two points specified in line₁.

lamina_i+10 - Uses the 'concat' function to create a character string out of the AutoCad command "z e region w," a space, a point described below, a space, the second point described below and a space. The purpose of the character string is to create a region based on the two points specified.

first point:

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

second point:

• x: lamina_last0 + t + amp
• y: lamina_last1
• z: lamina_last2

z: zoom
e: extents
region: creates a region based on two specified points.
w: specifies corners for the window in which the region is to be created.

lamina_i+11 - Uses the concat function to create a character string out of the AutoCad command extrude, a space, the point 'origin,' a space, a space, the variable 'l,' a space and the "0."

lamina_i+12 - Uses the concat function to create a character string out of the AutoCad command rotate3d, a space, the point 'origin,' a space, a space, the command "y," a space and a num2str (-(90-angle/deg)) if the angle is not 90 degrees.

lamina_i+13 - Uses the concat functino to create a character string out of the AutoCad command array, a space, the point 'origin,' a space, a space, the command "R," a space, num2str(num_bafflecols, a space,num2str_baffles and a space.

lamina_i+14 - Together lamina_i+14 and lamina_i+15 - for an if statement. Lamina_i+14 uses the concat function to create a character string that enters the dimensionless number "yspace" if num_bafflecols is less that 1.

lamina_i+16 -lamina - ₁₅ - Enters "" into the command line if the condition in lamina_i+14 is not forfilled.
