Check if there are any unresolved references

Hello everyone, 

How do I check if there are any unresolved references in the drawing?
(A function similar to the AutoCAD built-in: see below image)

Hi,

You can iterate through the BlockTable and, foreach BlockTableRecord it contains, check for the values of th IsFromExternalReference and the XrefStatus properties (see the XrefStatus enum).

Hi @_gile 

Thank you and sorry for my late response.

I successully checked xref of a dwg. But other xref types, for example: `UnderlayReference` or `RasterImage` does not represented as a BlockTableRecord.

How can I check these types of references? 

Best regards

Have a look at the UnderlayDefinition properties and RasterImageDef properties.

You should use a snoop tool such as MgdDbg or Inspector.

They are really useful tools!
