Chief Vs Autocad

[portrait]

Orbit,
For me, one of the strongest points of Chief is kitchens,baths and cabinetry.
Revit has some useful tools for renovation/remodeling that Chief doesn't, but you can't design a kitchen in Revit as easy as you could do in Chief. You may require some plug-ins.
Chief is what you need. There will be important new features and improvements for kitchen and bath designers in Chief X5, so you may want to wait until at least X5 Public Beta version is released to see if it really meets your requirements.
However as Scott said, it's not easy to draw all the manufacturing details of your cabinets with Chief. There must be more specialized programs on cabinet manufacturing such as this one: http://www.cabinetpro.com/
Alternatively you may use Chief and Autocad collaboratively for manufacturing details.
Also you asked if Chief's 2D capabilities are as good as Autocad's. Frankly my answer is no. If you want to switch to half-BIM or BIM programs such as Chief,Revit,Archicad,etc. then you shouldn't expect Autocad level CAD capabilities.
