You most likely won't get a lisp answer in the CAD General forum.

Hi Andrea,

I have just done some programming using xdata. I had a hard time as well trying to figure it out. This is what I could make of it.

To make xdata you have first make a 'regapp' call. In my case it was something like this:

Code: [Select]

(regapp "JIDH-XDATA")

When the xdata is made (as in your case) and you want to retrieve it, you need to make a call to that name that was passed to regapp:

Code: [Select]

(ssget "X" '((-3 ("JIDH-XDATA"))))

-or

(entget (car (entsel))'("JIDH-XDATA"))



So I think that you first of all need to know the regapp-name that was given to the xdata by the application.[/quote][/code]

I'm not sure Mark, but I thought XRecords were not attached to entities?
I use Xdata to attach additional data to an object that I can retrieve later when this object is selected.
Is that also possible with Xrecords?

You can "attach" xrecords to an entity by adding an extension dictionary to the entity (read about GetExtensionDictionary method), then adding the xrecords to the extension dictionary.
