I would like to print lines in different thicknesses. I do this by setting "lineweight" in the layer-window. So all lines of a certain layer have the same thickness, regardless of the color. Is there a way to control the thickness by color, for example red lines are ..5mm, green lines .3mm, etc. My English is not that good, so I dont understand everything in the help of Acad. Is that right, what I found out? What I know, is, I can do that with plot style tables. But this creates a new file, and so I have to send with each drawing a plotstyle-tables-file, which is inconvinient for the other user. So I have to control the line-thickness only by layer. This information is within the drawing. Thanks, Andrea (ACAD2000)
