Does XREF/BLOCK have Boundary

[Anonymous]

How can you test if an Xref or Block Insert has been xclipped with a Boundary?

I don't see any difference in the 70 or 71 flags.

Thanks.

This should work.  Haven't used it since I wrote it, as it wouldn't work for what I wanted, but it will return the boundry of a xclip if it has one.

(defun GetSpatialFilter (ename / Data Dict tempDict)
    ; Get the xclip boundry
    
    (if
        (and
            (setq Data (entget ename))
            (setq Dict (cdr (assoc 360 Data)))
            (setq tempDict (dictsearch Dict "ACAD_FILTER"))
            (setq tempDict (dictsearch (cdr (assoc -1 tempDict)) "SPATIAL"))
        )
        (cons '(0 . "SPATIAL_FILTER") (member (assoc 100 tempDict) tempDict))
    )
)

Thanks this works perfectly.

As a side note, can the same be used to test if a clip boundary exists for Image, DGN, DWF, PDF ?

Don't know.  Don't really work with them, but I would think that you could test them with the program, and see what is returned.  It wouldn't harm any entity, as it is just looking at stuff.

You're welcome.

Nope, your routine did not work for the other object types.  Too bad.  Thanks anyways.

Looks like for images you have to look at dxf codes 13 ( size of the image ) and 14 ( points of clipping ) and compare them, because even when I inserted an image, it has dxf codes 14, so it seems they are always clipped.  But if code 91 is greater than 2, then there is some real clipping for sure, but the clipping could be the whole size of the image.
