|

#
|
|
# This module offers tools to create and manipulate basic 2D objects
|
|
#
|
|
# The module allows to create 2D geometric objects such as line, rectangle,
|
|
# circle, etc., modify these objects by moving, scaling or rotating them,
|
|
# and offers a couple of other utilities to manipulate further these objects,
|
|
# such as decompose them (downgrade) into smaller elements.
|
|
#
|
|
# The functionality of the module is divided into GUI tools, usable from the
|
|
# visual interface, and corresponding python functions, that can perform
|
|
# the same operation programmatically.
