Photomask 1

How do I compensate for line width when drawing a photomask? A line width of .010 could raise hob when working with .0150 holes.

Could you draw with linewidth 0.0?

Thanks for the response. Does this really work?

You can draw with linewidth 0.0 but how you print is another question. AutoCAD always measures to the center of a polyline so even if you draw a circle of diameter 0.015 with a linewidth of 0.010 the measured diameter would still be 0.015. If you plotted it, it would come out as a solid dot, just as it would look on the screen.

If you need the visual hole to be 0.015, draw a circle whose width is the thinnest you can plot and make the circle appropriatly larger.
