Retrieving detailed XRef info with VBA

Anonymous — Mon, 20 Aug 2001 07:38:06 GMT

I'm trying to retieve information about Xrefs (source filename, loading success etc.) contained within a drawing using AutoCAD 2000's VBA.

I've done this in the past by "parsing" Xref log files with a bit of string manipulation, but this is cumbersome and inefficient. The IsXref property on AcadBlock objects allows me to weed out the Xref entities in a drawing, but I haven't been able to gather any more information other than the Xref's assigned name.

Does the AutoCAD 2002 object library expose any extra Xref-specific properties?

Thanks in advance for any ideas.

You could iterate the space blocks until you encounter an object whose
objectname property returns "AcDbExternalReference" then assign it to
an AcadExternalReference variable. However, the AcadExternalReference
object doesn't offer much more than a path property.

To get around this limitation, you can either use VisualLISP (see
GetXrefPath and GetXrefType in the VB section of my site) or the
BlockEx class in vbXtender.arx (Downloads section). With vbXtender,
you can retrieve an xref's path and status (resolved, unresolved,
etc.) directly from the block object.

Good luck.

I am interested in anything anyone else has to say about this, with an
additional request for how to find out which, if any, xrefs might be nested
into others, even under the circumstances of none of them being resolved,
either because of a loading problem or that the files have been renamed or
moved. Thanks.

One way is to use the XrefDatabase property and iterate through each
xref's Block collection.
