Currently I'm tasked to research the different options available for creating UML diagrams, but since I have barely worked with them I find it a hard task and would like to ask for some help with the choice considering our scope.
The Scope Use Case and Activity Diagrams have to be presentable to the customers, so they should look decently visually and not like they're from the 90s. For huge projects where we think they will be important we also have to make Class, ERD and ORM diagrams. This software should run on Linux distro's
Question I had consider to find a piece of UML software that creates visually attractive diagrams for the Use Case and Activity diagrams. And then use a different piece of software for the in house creation of Class/ERD/ORM with the use of ArgoUML. Does anyone here have some experience with UML in a company that might be able to give me feedback that assists me in the creation of a well motivated reason why we should perhaps even purchase a certain piece of software for UML?
My apologies if this question is too open or opinionated.
I've also seen this list https://en.wikipedia.org/wiki/List_of_Unified_Modeling_Language_tools but it is hard to decide just from reading that if I don't have any first hand experience with them.
Also read this question What's the best UML diagramming tool? but it's 3 years old and doesn't really give any info considering the scope I have to look at.
Visio would pretty much fit all our needs in one software package, the price is just too excessive.
