[Anonymous]

i have made a isometrick drawing of a central heating system in difrent layers.

but when i plot it most of the lines just become ghost like half transparant. 

i have tried all plotting styles mono acad and all.

here you go i have found out that it happens when the size of the ploting paper gets bigger how bigger the size the more lines go ghost

plotting to what? a thin line gets thinner on a larger scale... .
Do you need color too? Apparently you do, but you make no effort to create any line weights in your line drawing that I can see.
Do you use plot style table? Apparently not in your sample.

See PDFs attached with various lineweights printed to a large paper size, zoom in to see them if your PDF viewer settings don't show it. I used a plot style to set line weights for each.

i wanted to plot to a iso A1 format.

no i didn't add any weight to my lines because some lines are totaly fine and others weren't,

i used most of the plot table's and in my previeuw everything is fine only not in the pdf file that is created.

yes i indeed needed colour but the problem was there too when i used monogroom or grayscale
