Need help modeling this:
sort of like a rectangular patterns going in on itself
currently im doing it line by line any easier way? maybe a patterns option

Thank you, I thought of this but keep in mind that design is 96” x 60” and the offset is 1” so this could also take a while, is this the best method?
Looks like it should only take 6 offsets.
Thank you
Hi Keval
Here's an off the wall approach!
start with a boundary surface or loft (something like this)
Now make a slightly larger helix that has the requisite number of turns and is the same height as your loft
use the helix and a sketch line along the axis to create another boundary surface
use sketch tools - intersection curve to create a 3d sketch of intersection
convert entities on the 3d sketch to a 2d sketch on the top plane to flatten it
surface extrude this sketch
up to this point in modelling it is possible to make this fully parametric,
but solidworks can auto select your internal edges for filleting
before finally converting the edge to a sketch
You could add fillets to your loft but I wasn't sure if they would stay true arcs or if you care.
You could also probably mirror your helical surface to make the opposite hand side.. I'm not sure I didn't test it.
Anyway some fun for late on a Friday!

Isn't one 180 rotation of the other?

180 or a two lead spiral? I'm looking at this as a single wire. Goes in on the spiral and then comes right back out right next to it.
You'd have to do what I did below twice, once for the outer track and once for the inner track and then lack them on top of each other and connect.
See if this makes any sense?
Start your sketch with the start of the spiral
Offset everything using Linear sketch pattern
Use power trim to trim out the corners
Delete the left overs
Voila!
Draw your first spiral. Offset that by whatever the distance is between the pair of loops (that's what it looks like to me anyway). Then, offset both pairs by double the original distance. Lather, rinse, repeat by offsetting the outside tracks by that larger offset distance. Extend/trim the lines as needed, then add the radii afterwards.
I did a quick one and it seemed to work.
