Sections of an item that are straight lines are drawn using two vertexes (for the beginning and ending points):

Correct Incorrect

The green arrows on the drawing below show correct usage; the red ones — incorrect usage (because there are too many vertexes):

Sections of items that are not straight should be drawn using as few vertexes as possible (while ensuring that the outline remains smooth at all map scales (all the way to 19):

Correct Incorrect

The green arrows on the drawing show correct usage; the red ones — incorrect usage (because there are not enough vertexes to make the outline sufficiently smooth):
