Additive Vs. Subtractive Manufacturing

I would like to get some input of the cross-over points between Additive and Subtractive manufacturing. Right now, I am working to gain employment in the manufacturing industry. I just graduated back in May with a degree in Machine Tool Technology, but I have been drafting since 1999. Moving into the field that I have always wanted to work in since I started drafting work. This would bring the other four degrees into focus in one career.
I work with SolidWorks and GibbsCAM as well as AutoCAD.
Now to the actual question.
How much are these programs used in the Additive manufacturing field?

Gibbscam isn’t used for additive manufacturing. It is for converting CAD models into g-code programs for subtractive manufacturing and has very little if any design capabilities. It is for subtractive processes only. Although I feel they are likely to add additive processes at some point.
Autocad has some 3D solids capabilities. Some use it for generating solid models for additive manufacturing but it’s not very efficient or capable. AutoCad is an excellent 2D design tool. Those that use it for 3D solid modeling do so only because they have nothing else. Even most free and low end solid modeling software outperforms Autocad for solid modeling.
Solidworks is an excellent tool for creating 3D solid models destined for additive as well as subtractive manufacturing. It is capable of doing most anything desired in those arenas.
Once solid models are created using AutoCad or Solidworks they require further processing by some slicing software. This converts the solid model into g-code instructions for the 3D printer. A slicer like Cura is the equivalent of Gibbscam but for additive manufacturing.
