I'm starting to use CAD for work, but also use it for home work. I have a basic grounding in technical drawing from my college design & technology course (many years ago!), so I do have a reasonable understanding of the principles. Most of my questions are really about best practise.
As an example, everything I've found says that you shouldn't put dimensions on the outline. I'm working on a drawing which is essentially a large plate which has some small hole details in the middle. To me it would seem cleaner to put the dimensions which relate the holes to each other near them, on the outline, rather than bringing extension lines all the way to the edge. Would that be considered bad practise?
