Reload Xrefs

If someone modifies an externally referenced drawing while you are working on the host drawing to which that xref is attached, you can update that xref drawing using the Reload method. When you reload, the selected xref drawing is updated in your host drawing. Also, if you have unloaded an xref, you can choose to reload that externally referenced drawing at any time.

Reload an xref definition

This example attaches an external reference and then reloads the external reference. This example uses the 3D House.dwg file found in the sample directory. If you do not have this image, or if it is located in a different directory, insert a valid path and file name for the PathName variable.

Sub Ch10_ReloadingExternalReference()

	' Define external reference to be inserted
	Dim xrefHome As AcadBlock
	Dim xrefInserted As AcadExternalReference
	Dim insertionPnt(0 To 2) As Double
	Dim PathName As String
	insertionPnt(0) = 1
	insertionPnt(1) = 1
	insertionPnt(2) = 0
	PathName = "c:/AutoCAD 2008/sample/3D House.dwg"

	' Add the external reference to the block
	Set xrefInserted = ThisDrawing.ModelSpace. _
			AttachExternalReference(PathName, "XREF_IMAGE", _
			insertionPnt, 1, 1, 1, 0, False)
	MsgBox "The external reference is attached."

	' Reload the external reference definition
	MsgBox "The external reference is reloaded."
	Exit Sub
	MsgBox Err.Description
