BCT (http://www.bct-technology.com/) has some plotting utilities that (I think) can do what you want.
Otherwise, you have to write code to run thru all open parts (or current part and all components, recursively) and plot any drawings. If component drawings are master model, then you'll have to figure out (from model filename) what the drafting file name is & open that.
Once you have the file open, plotting is pretty easy (try creating a journal, or searching the solutions database for examples)
Production: NX10.0.3.5 MP5 + patch/TC11.2
I'd rather be e-steemed than e-diseaseled
