Extending P&ID Symbols

This week on the forums djf posted a question about instrument buttons.  Eventually we came around to a feature I hadn’t thought about for long time…ok, I forgot it was there…sort of.  The good thing is djf was patient enough to wait for my memory to catch up with our conversation so we could get the issue resolved.
The trick is that P&ID uses two types of commands to allow drawing new symbols, and customizing the user.lsp allows us to take full advantage of CADWorx P&ID.
This pdf explains it all in detail, as it’s a little lengthy to repeat here.
The video is available for viewing here and shows how to insert P&ID objects from tool palettes.
