1) If you have multiple terminals that fully match your criteria for the wire and connector, the system has to choose one of them in some method.
I would have expected it to take the first one that matches and quit searching (to save search processing time) but they decided to search all and take the last one found.
We are just getting started with schematics and don't have any significant conflicts but I have included a Preference column in my terminator table that it is sorted by before loading. I would love it if they added a feature that would allow it to use the preference value directly in choosing the terminal.
In our case, I talked with our harness designers to find out what their preferences are. I created some formulas based on the other values that make terminals that fit our preferred wire sizes more preferred and others that are closer to them. ie: if we have a 12 awg wire (our typical sizes are 18-16 awg) and terminals that fit 14-12 and 12-10, the 14-12 is preferred. For seals, the one that fits tighter around the wire is preferred.
2) I don't think they really planned for multiple wires in a terminal but there are things that can be done.
Many of our connectors are sealed and only one wire is allowed per terminal. For the unsealed connectors, almost all the terminals have maker specs that are for one wire. Some of the unsealed terminals are designed for two wires instead of one. For terminals that we allow multiple wires (but were not specified for this by the maker), we will create separate line in the table for each number of wires that we will allow.
In general we have connector family, max and min sum wire area, Max and Min insulation diameter, and connection count. The connection count set specifically for each terminal that has options for 0, 1, 2 or 3 wires. 0 wires is used for cavity plugs on our sealed connectors.
This is where it helps to have a consultant to help you set up the system and answer questions you have afterwards. The software is complicated enough and the documentation is skimpy enough that we would have been totally down the wrong roads many times (it still happened to a lesser extent) without a consultant's help.
