Polygon

Make a line betweeen two points

line  = Part.makeLine((0.5, 0.5, 0.5),(1, 2, 3))
line2 = line.copy()
testEqual(line, line2)

Make a plane (rectangle) from origin 2 units in x direction and 4 in Y direction.

plane = Part.makePlane(2, 4)

# there seems to be a bug here?
#plane2 = plane.rotate(o, z, 20)
#Part.show(plane2)

plane2 = plane.copy()
testEqual(plane, plane2)

plane2.rotate(o, z, 20)
testNotEqual(plane, plane2)

Make a polygon of a list of points

poly  = Part.makePolygon([o, x, y, z])
poly2 = poly.copy()
testEqual(poly, poly2)

poly2.rotate(o, z, 20)
testNotEqual(poly, poly2)
