So first off I know uploading a blueprint/image is probably needed for full assistance which I can do but not until later. But I am trying to create a blueprint of a city block I created that includes my rails and intersection (2 rails with a fourway at each corner) but I don't seem to understand how to set up the snap to grid because i can't seem to get the rails to line up for the grid. I'm not sure if I am messing up with the dimensions of the grid or with the offsets. Are there any tricks to getting this too work or anything like that?
Best way I can describe it is starting at a corner, which includes the rail intersection, then stopping the boundary at the opposite corner without including its rail intersection.
Just to be sure I'm understanding correctly, this would then basically make it so that the rails on two adjacent sides would be included and the other two wouldn't to allow for overlap?
