Lineweights in drawings

Here is a good essay about how to effectively use line thicknesses to convey information in drawings:

I wish the programmers at AutoDesk (AutoCAD is the product) had understood the importance of lineweights back in the 90’s. They seem to now, but for years it was practically impossible to do drawings as well as an average hand drafter could, because the tools were so poor.

It reminds me of typography, which went way down hill when computers came on the scene. Now, typography is making a strong comeback. I hope the same thing happens for drawing.
