You can center the pattern of a linetype on each segment of a polyline, and you can control how the linetype is displayed on short segments.
If a line is too short to hold even one dash sequence, the result is a continuous line between the endpoints, as shown below.
.You can accommodate short segments by using a smaller value for their individual linetype scales. For more information, see
For polylines, you can specify whether a linetype pattern is centered on each segment or is continuous across vertices throughout the entire length of the polyline. You do this by setting the PLINEGEN system variable.
