Suggestion for the LOS-Tool:
As this gets more and more developed, I reckon most people do use it with the preference of "snap to grid" (i.e. center dots or vertices). Interestingly, using VASL v6.4.1, my LOS normally snaps to grid even with that option not checked.
There are some instances of atypical LOS (Road use, A4.132), though, that use neither the center dot nor vertex to draw a LOS.
For these cases, it would be handy if the VASL Map window held a button (or allowed to add one), that switches on/off the "snap to grid" function of the LOS that needs otherwise to be adjusted via Files/Preferences/LOS/Snap Thread to grid. This function would also be handy to be able to string a LOS if the result given by the LOS tool is apparently incorrect [EX: 20X2 to 20L8 clear, 20X2 to 20K9 and 20J9 hindered, and 20X2 to 20I10 clear again] or slightly offset.
