I was offering some advice on how to automate the process using autolisp. Since that is not something you are versed in, not to worry.
Using just good old fashion AutoCAD commands you can accomplish the same thing.
Since you apparently already know the size of each polyline set of entities, start by creating a grid of lines.
Draw a vertical line from 0,0,0 Straight up to say 0,10000
LINE[Enter]
0,0,0[Enter]
@5000<90[Enter]
[Enter]
Next use the offset command
Offset[Enter]
4503.58171203[Enter]
[Pick the line we just drew and offset it to the right then repeat the process until you have however many horizontal instance you will need.
Then create the horizontal lines of your grid.
LINE[Enter]
0,0,0[Enter]
PER[Enter] Pick the last line you offset in the previous step
[Enter]
Then offset that line as needed
Offset[Enter]
3230.42834255[Enter]
[Select line drawn in previous step and offset up, repeat as often as needed]
Then just use the good ole move command to grab the contents of each drawing use the lower left base point and then pick your first location of 0,0,0
Repeat the process until you are done using the line intersections on the grid you created to place each one.
Hope that helps you get going. Over all it should only take a couple of minutes to format the drawing contents that you have to the desired arrangement.
