MicroStation Specific Information 

 

S = W / 25R

    where: 

S = # of strokes in weight strokes statement of driver

 

W = desired width of line in millimeters

 

R = resolution of plotter in inches in resolution statement

A-size 1000dpi (0.025 - 1.6 mm)
weight_stroke=(1,1,2,3,4,5,6,7,8,9,10,11,12,14,16,18,20,22,24,27,30, 33,36,39,42,45,48,51,54,57,60,63)

B-size 1000dpi (0.05 - 3.2 mm)
weight_stroke=(1,2,4,6,8,10,12,14,16,18,20,22,24,28,32,36,40,44,48,54,60,66,72,78,84,90,96,102,108,114,120,126)

D-size 1000dpi (0.1 - 6.4 mm)
weight_stroke=(1,4,8,12,16,20,24,28,32,36,40,44,48,56,64,72,80,88,96,108,120,132,144,156,168,180,192,204,216,228,240,252)

A-size 300dpi (0.085 - 1.6 mm)
weight_strokes=(0,0,0,1,1,2,2,2,2,3,3,3,4,4,5,5,6,7,7,8,9,10,11,12,13,14,14,15,16,17,18,19)

B-size 300dpi (0.085 - 3.2 mm)
weight_strokes=(0,0,1,2,2,3,4,4,5,5,6,7,7,8,9,10,12,13,14,16,18,20,22,23,25,27,29,30,32,34,36,38)

NOTE: 0 strokes produces a line of minimum width. On some plotters this results in a thinner line than the plotter resolution would indicate (ie. thinner than one stroke).

Resulting line widths (mm)
