Update/Migrate Entity Type From One Type to Another

[lreading]

Describe what problem your feature request solves Entities are unable to be changed after they are added to a diagram (Store, Actor, Process). This is problematic when a diagram changes or is first being defined. Additionally, when an entity is removed from the diagram, all attached flows are removed as well.

Describe the solution you'd like In the context/edit menu for an entity, there should be an option to change the entity type. The only supported changes would be between Stores, Actors and Processes.

Additional context This was suggested by Simon S

This is an excellent suggestion by Simon. A point to note is that the data flow connections will have to be preserved, and this change will have to be intuitive but not done accidentally ... a difficult thing to get right without too much clutter on the right hand pane?

I'm almost at the point where this could be in the near-term for v2. In v2, data flow connection points are (mostly) managed by the underlying drawing package, and will move based on anchors and other context. You can put flows at arbitrary points on the graph, but they do snap to other objects. When they snap to an object, instead of having absolute positions (eg x: 23, y: 250), they just reference the other object.

In short, I think it will probably work out fine in most situations, as the drawing package should be intelligent enough to make small adjustments on the fly.

It is unlikely we will be able to get this into version 2.0, so I have marked it for the later 2.x version

Closing this as a Won't Do It would complicate the tool, Threat Dragon is deliberately lightweight compared to Microsoft TMT, and we need tokeep it simple - otherwise we start competing with MS TMT
