You can try this one:

ansi32.dxfIf this is correct, I can add it to the pattern folder for further releases.

The trick is, that the pattern in the 100 x 100 square must be continuous on all 4 sides.

You can check this by copying the pattern and applying it to all 4 sides of the origin.

The ansi31 pattern has 50 lines per side. There is no special pattern, so any number of lines will work, until the distance between the lines is constant.

The ansi32 pattern in contrast has a lowest common factor of 3, means 2 lines and 1 gap. So the number of segments per side has to be a multiple of 3. I used a factor of 100 / 48 for the distance between lines and gaps. Then started with a gap in the main diagonal and applied the pattern lines on the left and bottom for the ansi32.dxf file.
