function projection_result = scadProjection(object, varargin)
%scadProjection - Using the scadProjection function, you can create 2d
%drawings from 3d models. It works by
%projecting a 3D model to the (x,y) plane, with z at 0. If cut=true, only
%points with z=0 are considered (effectively cutting the object), with
%cut=false(the default), points above and below the plane are considered as
%well (creating a proper projection).
