New Features

Choose Custom Fonts

Not happy with the hand-drawn default font? No problem, you can now choose any font that is installed on your system for your diagrams. Just go to Settings, switch to the Diagram tab and choose your favourite font from the dropdown box.

Custom Fonts


UMLBoard now supports setting multiplicities for association. For this, just click-and-hold/double-click on the lower or upper watermark text of a connection and start entering the lower and upper bounds of your multiplicity. Please also check out our new online help for more infos.


Editing via Double Click

Pressing and holding for editing is too cumbersome or takes too much time? No worry, you can now edit every text by just double clicking on it. Press-and-Hold still works, of course.
