EN LT, Line Type 22-25
Figure 22-17 first shows the line type patterns, then gives the pattern

Note Do not use an adaptive line type when drawing circles, arcs, wedges,
or polygons. The printer attempts to draw the complete pattern in
every chord (there are 72 chords in a circle using the default chord
angle).
