Hi Brad, I have to do multi-sheet schematics often and had to figure out a way to do this as well. The method I use is not too complicated. I create a 'dummy' master sheet as the first sheet of the schematic and us the command Design/Create Symbol from sheet to make a Sheet symbol for each page of the schematic and place it on the 'dummy' master sheet. This makes the sheet symbol automatically get filled in with the name of the file for the sheet it represents so you don't have to enter in manually. Then the trick is in selecting the right options in the Design/ Create Netlist command. I choose the Protel Output format, the Net Identifier Scope set to 'Net Labels and Ports Global', the Sheets to Netlist set to 'Active Project' and the check boxes enabled are 'Append sheet numbers to local nets' and 'Descend into sheet parts'. As soon as you generate the netlist the Design explorer recognizes that the schematic is a multi sheet schematic and rearranges the order into a hierarchical order indicating the dependence of the sheets on the 'Dummy' Master sheet. That seems to work for me. Hopefully that gets you going.

Hi all, well I finally had to break my normal pattern of flat hierarchy this morning. I am having difficulties getting sheet symbols to connect to the subsheet ports. Everything netlists and updates to the PCB just fine except for the 4 points that connect between sheets. What am I missing here? I have checked that the ports seem to connect to the wire at the correct point. This is not the easiest, nor am I sure of this one, because the electrical snap grid doesn't work consistently. It doesn't always show me the enlarged dot when I try to connect to the port, sometimes it does but not always. I have 4 ports, IP1, OP1, IP2 & OP2. In my sheet symbol they are set as input, output, input & output respectively. On the subsheet I have the ports set as output, input, output & input respectively. When synchronizing I have ports and nets set to global. The only thing that doesn't connect are the 4 port connections. What am I missing guys? Sincerely, Brad Velander.
