Line style (such as dashed) applies to certain arrow styles (crowsfeet and hash marks), but should not
Entity Relationship Diagrams require dotted lines, but half or more of the hash mark disappears depending on dash length (such as .2). Double hash marks are affected at different offsets.
Affects:
(ascii art is used to represent the shape of the ends--E is crowsfoot)
- -I-I- (or "exactly one" relationship)
- -O-I- ("one or zero" relationship)
- -E and -O-E (only center prong is affected, but sometimes missing completely such as right/end at 0.20 dash length, making it 2-prong which has a different meaning)
