I did a symbol with ptc_wm_revision which is a system parameter. In my symbol the text is \ptc_wm_revision\.

Hi Ben,

Yes normally in a drawing symbol you use the syntax \text\ to create a variable field in the symbol. The preset value can then be used to call out the model parameter as &param_name, etc. But when you try and use the modifier :att_mdl it doesn't work. I haven't yet found a way to nake this work, but when I add a leader note manually and use :att_mdl it calls the parameter fine.

It's been a while - what does att_mdl represent? Ok :att is to say "get the attribute from the exact part or feature in an assembly that the arrow is attached to.

I used to have a full list of all the parameters available to symbols, but have lost track of it. A reminder of the parameter might jog my recall.

Maybe it isn't possible - what would the symbol fill in if there is no leader?

I do know that custom symbols defined as replacements for BOM balloons can have the model name as a parameter; those are guaranteed to have a leader to identify what they apply to. Perhaps make a repeat region and assign a symbol there and just hide the table.
