i have tried to draw by using UML2Tools for my Software Modeling .
so i works to draw on Class Diagram, Composite Structer Diamgram and Use
Case Diagram.
there are many problems as lines are displayed and i can't text in such
slot or name of the association line, can't add other relationship line.
other way,if i add a line then double line drawed once.
i need a <<use>>line on Use Case Diagram but it's exist.
really it seems not able to work with complete feature i need for UML2 on
UML2TOOLS.
