Is it necessary to use CTB ?

hi,

im always used to change line wieght color and type in VP color, VP wieght and VP Style tab in layer properties manager, and im printing drawing with CTB NONE .

I was using microstation, in microstation we use symbology so i tried that style in autocad using vp color.

please let me know is their is any disadvantages in this method?

Just found over the years that a red line is that thick a cyan is thicker a blue is real thick much easier than playing with line thickness's and having to think about it. Just know thick and thin.

Maybe thats why I am a bit thick at times thinking about it.

DWg standards ?

Could have beaten one of guys up for playing with VP colours and linetypes because he discovered he could change it because it looked good on paper ****** everybody else that opened up his drawing and said what the !#$%^ has some one done and didn't know you could do that sort of thing.
