Line weight configuration for printing.

Unknown said:

Hello,

I am relatively new to Microstation and I am having trouble printing my work for University. My tutors didn't explain much about the printing options in the program and I don't know how to set the desired line weight for a layer when printing - for example, I'd like that the 0 line weight to print as 0.05 mm on paper. I have been told that the line weights in the design file are preset and can't really be changed, but if that is so than I can't really print my work properly. 

If you could please take me through the printing options I'd be very grateful as the final submission date is around the corner and I can't get my head around this isssue. I am attaching the file I am currently working on. I should mention I am using the student version of Microstation.(Please visit the site to view this file)

Thank you in advance,

Claudia

Are you sure of that weight   0.05 mm ? I dont know if printer resolution  can actually  produce  5/100 th of a mm, 1/20th mm ok I test it and it  worked

I have  modified the pdf ,plt to use this pen width for  weight 0, 

use this instead of the  one in  microstation  you can put it anywhere and  browse to it with choose a bentley  driver...

It may print a line but is the line really only 0.05 mm? Were talking about a line the thickness of a human hair.

I know ! as you can see I questioned her about it too but heck it worked on my EL cheapo A4 B&W laser printer  so  who are we to judge.. 

FYI for those interested 600 dpi works out at 23.6 DPmm so  each dot is 1/23.6 th of a mm and  0.05 is 1/20th of a mm  which is bigger or fatter  so its possible

Now I've seen a hair  photocopied  in error and its  quite  visible on white  paper so it works  but would I use it in drawings? Not on your life!

But  she asked  for 0.05mm and  we gave it .. personally I think it was a typo and she meant 0.5  or even maybe 0.15  Which I have used... for 0 before...

but now she has a  offline copy  of the pdf.pltcfg and  previous posts she can edit it herself if need be..

Your math assumes each dot is spaced with no overlap, which isn't always the case.  Additionally if your doing these lines in color you need multiple dots to create one color.  Something like an 8x8 matrix to get 24 bit color.  Good article here which shows why 1440 dpi yields a color cell resolution of only 180 dpi

Thanks a lot for that David a really interesting article.

I only  meant  to convert imperial DPI dots per inch  to Dots per mm so it  would make sense to me and others

as I was trying to make sense of the  line width 0.05mm 

We all hear the DPI' s bandied about  by  printer vendors  and  now I see its all over rated and used with the  intention  of misleading the  buyer... but it is true rating  system though  but only relative that  the  higher the dpi the better versus each resolution quoted..

but in any case  it was in the realms  of possibility as a B&W printable  line width... so I tried it and  it does  print  but I didn't  measure the  line with a loupe or  microscope  vernier to get its true  width, as  it  just may  be my  printer  prints at the minimum width possible.. but it sure was very  fine on paper with using my a4 samsung  B&W  600 dpi  laser
