Hi Gufran,

This is my (very) biased opinion, but depending upon what you mean by framework, have you considered using Visual Paradigm Community Edition?

There might be other good tools outthere, however with this one I was able to write quite some good UML for my M.Sc. and P.D.Eng. theses.

Hope this helps. Greets,

Hello Gufran,

Currently i am using Violet UML Editor which is a very simple UML Editor it supports:

• use case diagrams
• class diagrams
• object diagrams
• state diagrams
• activity diagram
• sequence diagrams

The tool is for free and licensed under GNU.

Dear Gufran,

I used "UML Designer 6.0" under Eclipse platform too. You can try this open source tool as well. Please, follow the following link:

https://marketplace.eclipse.org/content/uml-designer

Or, if you had an installed release of Eclipse such as Mars, Luna, etc., you can automatically find, install and configure the UML designer from the "Help>Eclipse Marketplace..." menu too.
