1 year ago If, as I suspect, liberating the model is not possible, then redrawing the diagrams will be the way to go. The big question is: Should this be done with a simple drawing tool or with a UML tool that supports a proper model?
- For simple drawing a very interesting tool that I didn't have on the radar last time I looked around is PlantUML. Using this would guarantee the freedom of the data, which is a very strong point after the Astah disappointment.
- The open source modeling tool Umbrello has been given a new life, it seems, since I last looked in 2012, so this should be the first modeling tool to have a closer look at.
- Visual Paradigm still offers a free Community Edition. The question is if they still have the crippling limitation with only 1 diagram per type that I saw in my evaluation of UML tools in 2012.
- On the commercial front, Sparx Enterprise Architect remains interesting because it still supports buying a license, i.e. no subscription model.
Astah is no longer available in a community edition 😟. Try to find a way how the UML model can be extracted from
littlego.astaand converted into a format of another free - preferrably OSS - UML tool. Bonus points if the diagrams could also be extracted/converted.
