Once you select all your segments you want to include in a PL, one very important step is to zoom out so you can '''see them''' all on the screen, and then '''center''' your view in WME on those selected segments.
Keep in mind that anything [[User:Dsfargeg/Road_Types_and_Zoom_Levels|farther out than Zoom4]] will usually fail to produce a functional PL
. PLs created when segments are not centered or not in view will usually fail to open correctly in WME when clicked on.
So save yourself some grief and remember to keep the screen at maximum of Zoom4 and centered and THEN create your PL!
