Equipment Drawings and thickness of lines

[rollingstein]

Warning: Rant ahead

I get more and more drawings from vendors where all lines seem to be of the same thickness. Makes it awfully hard to tell if a line's a dimension line, a leader, a projection or a real part outline.

Do others share my annoyance? Is this an evil of the post-AutoCAD era? Or is this when they send me those as pdf's?

It's not just some iffy small vendor, but even reputable ones seem to send such uni-darkness line drawings.

Has the legacy of 2H, H, HB, B, 2B etc. been relegated to the trash can? Or am I unusually unlucky in encountering these moronic draftsmen?

Sigh.

Its all too easy with 3d models. No one actually teaches good drafting anymore.

Also overcrowding of the page is my main irritation. I also hate when people dimension to hidden features. With cad systems it's just so much easier to create a new view.

People need to be forced to draw something on a board. Its a vital skill to plan the drawing in your head before you ever put pencil to paper.

Another thing I sorely miss, was the utility in paper drawings of projection lines between views. Merely by tracing down or horizontally one could often correlate features.

CAD has added liberty about placing views and made this so hard to decipher.

Anyways, asides of ranting, any constructive solutions to these problems? Surely CAD can be used in smarter ways? Have people seen CAD drawings that were exemplary or a pleasure to work with? I'd love some as examples to smack the next vendor on the head with when he shows up with one of their typical atrocities.

find (or write) a standard, and tell your suppliers to conform to it
