Anyone knows if fabrication detailing can be done in Revit? Which other software enables it?

yes, Autocad mep

I'd add Inventor to the list too.

It has also Autocad Structural Detailing. Have a topic in CAD ​​Fórum?

No, you can use the AutoCAD forum for AutoCAD SD questions. As for fabrication - Autodesk has a whole family of fabrication tools - see Autodesk Fabrication at:http://www.autodesk.com/products/fabrication-products/overview
