Photomask

Photomask

Photomask

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

RE: Photomask

Could you draw with linewidth 0.0?

Thanks for the response.  Does this really work?

RE: Photomask

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.
