Drafting Standards - Standard Colors and Line Weights in CAD 

That is very close to the colour system I have been using since the early 90's. Pen Weights Green = 1.00mm Blue = 0.70mm Cyan = 0.70mm Red = 0.50mm Yellow = 0.35mm White - 0.25mm Magenta = 0.18mm Grey 9 = 0.15mm Solid Hatch Screening 250 = 90% 251 = 70% 252 = 50% 253 = 30% 254 = 10% 255 = 5%

Thank you! Great explanation of where the Auto CAD lines color coding came from!

I've been using civil3d for a few years now, pretty much self taught from youtube. Your work is excellent, keep up the good work

Very useful and to the point, thank you!

Thank-you. That has really helped me.

Great video.

Colors corresponds to line weights 👍

How do you change that thing you mentioned 'use object by lineweight and not colour by lineweight' in case I want to work with a white background?

Unforunately drawing presentation is seen as an afterthough, & little wonder we get queries from our manufacturers daily. Half my team don't even know about AS1100, & i'm the youngest there........

Does ,for example, 0.25mm line weight in AutoCad mean the exact .25mm in reaity?

what your font ?

Yep theres no standard anymore, Dont even start on 3d modeling programs.....thats a rabits hole, take a flash light. Cooperations no longer have the monopoly on programs, with the advent of serval free options, Which is great! But - being able to model isnt the same as producing a legible document. I didnt remember the line weights / colour rule and tended to draw with line type colour settings, Now I want both......but thats still not a standard. There needs to be perhaps seperate ones for seperate disaplines.

6:16 there's a fart

I don't understand. what are standards in autocad?
