I'm doing a schematic for this in OrCAD capture CIS. In laying out my schematic I need to draw one wire going through another wire, but not necessarily intersecting with it via a node. When I drag a wire through it it automatically creates a node there at the intersection. Is there a way to draw these two wires overlapping but without a node?

Create a footprint with GND and AGND pads. Draw copper between these pads. Yes, this will produce a DRC "Overlap" error as shown below:
This is OK. There three buttons at the bottom:
- Clear all
- Processed
- Approve
"Clear all" will temporarily clear the list for this run of the DRC. I'm not sure why that's useful; just close the window if you want it shortened.
"Processed" will fade out the color of the red X. This is potentially useful if you're iterating through a long list of DRC errors and fixing them as you go; you can keep track of the ones you think you've corrected.
"Approve" is the only one I use on a regular basis. This moves the error from the errors list to the approved list:
and keeps it there on subsequent runs of the DRC. Note that this only moves this specific error with this specific pair of nets at this specific location. Closing this window and running the DRC again produces the notification "DRC: 1 approved errors"
and no "DRC Errors" dialog. You can get this dialog back by creating an error, or (preferably) the errors command, the yellow exclamation point in the above screenshot, or the menu Tools -> Errors.
The "Approve" functionality exists for a reason, the same reason that we have tools like
#pragma GCC diagnostic ignored "-Warning"
Sometimes, it's OK to ignore a DRC error. This is one of those times.
I think that you can safely assume that the inductor symbols are indeed ferrite beads. I base that on the filled rectangular block used for inductor L2.
R18 is an adjustable resistor (potentiometer). The arrow indicates the clockwise direction. That is: the wiper moves Down as the shaft is turned clockwise. Note that this could be a front-panel adjustment or a trim pot on the PC board - there isn't enough information to tell.
I can't offer an opinion on which ferrite bead you might use but I frequently use Digikey part # 240-2563-1-ND - this is a Laird-Signal Integrity Products LF0805A252R-10 FERRITE CHIP 2500 Ohm, 100 Ma in a 0805 package. If I recall correctly, DC resistance is significantly less than 1 Ohm.

I use orcad 16 and if you drag a wire that crosses another wire where that wire connects to a component it will justifiably make a connection. Just ensure that dragged wires don't intersect at component terminations.
