“I made patterns of dots at precisely one-drawing-unit spacing (so I can get the spacing I want directly by way of the hatch scale) in three arrangements: a square grid, an accurate 60° triangular grid, and, while I was at it, a hexagonal grid with a one-unit hexagon edge rather than across-the-hexagon ‘diameter.’ And although I encountered a reference on the AutoCAD Customization Discussion Group to what someone called ‘the standard sqdots pattern’ for a square grid, it’s not part of my AutoCAD, though it may have been added in a later version. Also, their dot spacing is very peculiar (0.0625 units, for some odd reason) therefore, if you want a particular dot spacing, you need to do some calculations to get the hatch scale you need to use. “I was a little surprised to find that in AutoCAD’s/Architectural Desktop’s dots and general dots hatch patterns, although it appears that the ‘dots’ they draw (really zero-length lines) are in a triangular grid, they actually are not. Kent Cooper didn’t like the dot hatch patterns in AutoCAD, so he made his own and shared them with us.
