The OP of this thread wants preventative measures in place to stop stations and or blueprints from being spawned at or near sector boundaries as crossing sector boundaries tends to cause problems.
Either a warning/error message that pops up telling the player that if they spawn the blueprint/station at their current position then it will cross the sector boundaries or an automatic correction that slides the blueprint/station into a more comfortable point in the sector.
Theres also the potential for some game play enhancements viz allowing players more precise placement similar to the copy paste in build mode.
