API Updates:

ObjectARX : No New APIs.

.NET : No New APIs

Activex:

AcadApplication now supports the progIds “AutoCAD.Application.23” and “AutoCAD.Application.23.1” and AcadComparedReference has been added.

The AcadComparedReference object represents the drawing in which you are comparing the current drawing against. AcadComparedReference inherits from the AcadExternalReference object. The following is a basic example how you might go about determining whether an Xref is of the AcadComparedReference type:

' Checks to see if an object is of the ComparedReference type
Sub CheckForComparedReference()
Dim ent As AcadEntity
Dim comRef As AcadComparedReference
On Error Resume Next
' Step through all the objects in model space
For Each ent In ThisDrawing.ModelSpace
' Check to see if the object is a Block Reference
If ent.ObjectName = "AcDbBlockReference" Then
' Try to cast the entity (Block Reference) to a ComparedReference
Set comRef = ent
' If an occurs, then the entity is not a ComparedReference
If Err <> 0 Then
MsgBox "Not a Compared Reference"
Else
MsgBox "Xref Name: " + comRef.Name + vbLf + "Compared Reference"
End If
' Clear the Error object
Err.Clear
End If
Next ent
End Sub

AutoLISP:

There are no new functions or additions.
Xrefs related to the Drawing Compare feature are known as ComparedReference objects. The following is a basic statement that demonstrates how to return the IsComparedReference property of an external reference to determine whether it’s a ComparedReference object

(getpropertyvalue (car (entsel)) "IsComparedReference")
