Thanks for the question as I also used this to help learn the task at hand. Linestyles.
The things I learned is that where the Origin is placed in your cells makes a difference.
Also that if you Justify a symbol it will not "stick" during placement. Resulting you working aon fixing something to just find out the last half hour was because the justification changed.
I started with the same results as below but whated to make sure the line ended with a directional arrow.
I had to basically use a stroke with both a gap and a dash.
The dash was for the arrow - and an end point for a triangle
The arrow varies but you always end with a direction.
ARROW3 is the final choice but I realized there are two different versions needed.
1. that follows the path - right angles and all.
3. that bends at an angle when turning - more like a path of how people travel. (The one attached)
Arrow3 is what is shown. Met my criteria for always an arrow at end.
Though needs to be tweeked by someone smarter than me so that the end of the line is the point.
I never could acheive a 90 degree turn. That would be nice - any HELP here?
If follows your active color and it will change in size by Custon Line Scale.
