Detailed Description

The Loop class Allows for looping over a set of entities.

Example (lua):

l=Line(Coord(0,0), Coord(10,100));
d=app.currentDocument()
b=Builder(d)
b:append(l)
b:copy(Coord(0,0))
b:rotate(Coord(0,0), math.rad(45))
b:loop(7); – loop 7 times over the copt/rotate operations
b:execute()
