Abaqus - Steady-state detection

Hi. I am trying to conduct some steady-state detection analysis on rolling. The example that I am looking at is 2d. For steady-state detection, only 3d analysis can be used, as stated in https://abaqus-docs.mit.edu/2017/English/SIMACAEANLRefMap/simaanl-c-steadystatedetection.htm

So I have two questions: 1. If I simply extrude my 2D rolling setup will that work as 3D? I extruded and then wrote an .inp file and I don't think there is anything about the extrusion in the .inp file so I am wondering if this will work or not.

2. For the norms SSFORC and SSTORQ, I do not know what to put down as the "rigid body reference node number". As can be seen from this screenshot, the node number of the centre of my roller is 1 but this doesn't work and gives me errors when I use 1 as the "rigid body reference node number".
