I downloaded and have started playing with the free trial version. I am able to open an existing prjpcb file that has 5 schematic sheets. However, I am having difficulty finding how to extract a netlist from the schematic.
Or for the whole project netlist, type 'netlist' in the search box at top right of CS window.
From the schematic editor you can generate an EDIF netlist (Outputs | EDIF for PCB), within the PCB editor a netlist can be generated using Tools | Netlist > Export Netlist from PCB and Tools | Netlist > Generate Netlist from Connected Copper.
If looking to transfer a netlist to create a PCB when this is done by creating a blank PCB (File > New Document > PCB) and then from the schematic using Home | Update PCB Document.
