Any advice that disconnects the data from the model is simply bad practice. Now I'm not going to say that there might not be any instance where the above might not prove usefull for something, just not this particular instance or application.
My base plate details and steel connection details are detached from the model, and drawn in paper space.
If you can provide a way to quickly replicate these crucial drawing elements from drawing to drawing, I will welcome the solution. Like I said, there is -no- rule that is always good or always bad.
Design information is crucial to attach to the model itself. Other minutia that falls into the realm or repetition and efficiency of rolling out - do not. Not every little detail needs to be modeled and have details attached to that model. To do so is a waste of time, loss of time that could be devoted to tasks that matter. Ask me how I know.
Sometimes it's paramount to have details and pieces drawn in paperspace and dimensioned there. Situations exist. The OP asked how to make his stuff work, I answered. It's not up to me to tell him the best drafting practice and to conduct a background interview of his shop practices before offering him a solution.
