Replace record format information in symbol instances

Recommended Posts

I would like to create a script that replaces the content of an attached record format field in symbol instances that match the currently selected symbol instance. My thought is that this could work in one of two ways:


1. replace the record format field contents in other instances, or

2. replace the symbol instances entirely with the currently selected symbol instance, all of which are based on the same symbol definition.


Does anyone know of a similar script out there? I have used VS many years ago and am very rusty, but a similar script might get me to the goal faster.

Hi @David Poiron Try the script below and see if it works for you. You set the record and field in the Const block at the top. The script then checks to see if the first selected object is a symbol. If it is, it then reads the symbol name and the value of the Record.Field specified and stores that same value into every other instance of that symbol in the drawing.


Ask again if you need more help.

If you can specify the correct Criteria, ForEachObject is usually the cleanest solution in VW. It eliminates your having  to manually handle Handles and worry about when you are done. 😉


ForEachObjectInLayer and ForEachObjectInList can also be useful. They take a Function that returns a Boolean for success for Execute (or whatever name you want to use) rather than a procedure.


I used to use DoIt (Do it) as my callback procedure name. Until someone jokingly said they thought it was DOLT and I was insulting them for not knowing how to do it. I hate Sans Serif fonts.


Let me know if you need more help.
