Outline Creator is a 3ds max script that will automate the process of creating outlines for shapes instead of doing it manually one by one.
Gap : the distance between each line. Note make sure the system unit and the display unit are the same.
Num : number of out lines, if set to 0 it will repeat the shape until it closes.
Sys units = Inche : in case your system units are Inche and display units are centimeters.
