Overwrite symbol only if not modified locally?

[CadUser46]

Im trying to find a way of identifying if a symbol either has been modified locally or is different from the definition in our symbol template.  I cant see anything obvious in the api of the sketchedsymboldefinitions, or sheet.sketchedsymbols that would either show a flag or allow me to compare the two.

Has anyone come across this problem and found a solution?

Hi,

The only 'difference' I could think of is the prompt text or property text. In definition, they are just defined. When the user insters a symbol, the text will be set. So, I am not clear on the 'difference' you refer to. Could you elaborate it?

Basically i have a library idw and the actual drawings. I want to check if any symbol has been modified by the user and/or is different to the library. Local modification is allowed in certain parts of the workflow so i dont want to overwrite during a macro. The particular symbol that prompted the question is not a prompted entry so i may need to remake them as such and have my macro fill with the correct text at an earlier point in the workflow.

In case i was not clear i will try again. I want to know if a user has modified a symbol in their drawing so that it is now different to the one they copied and inserted from our library.idw.
Im trying to write a macro that only overwrites if it matches the library definition (because i can update the library definitions) but ignores it if a user has modified it locally, presumably because its a non-standard scenario. I dont want it to be reset in the second case.

Hi,

assume there are geometries, static text, prompted text and property text in a symbol definition.

after the symbol definition is inserted as a symbol, it would be:

for the result symbol, the user can only change the prompted text result string. He cannot change geometries and static text. as to property text, it depends on the corresponding property. 

So, if you want to compare the result symbol. You could only compare the prompted test result string, by SketchedSymbol.GetResultText.

If you want to compare the symbol definition, you will need to iterate each sketch element and check if they are different.
