The node does create a groupe if it doesn’t exist. “Dereferencing a non-pointer”. My guess is that if you check the log file, it would say something like this : " ERROR: Could not find unassigned subassembly 'LaneSuperelevationAOR".
The import stock subassembly node adds the subassembly to the drawing (if you dont specify a point it will add it to the origin) and the Assembly.AddSubassembly node, assigns the previously added stock subassembly to the assembly (using its nickname).
The tool name corresponds to the tool palette category
