AutoCAD has no Bind option available to bind raster images to a drawing.
In Revit when exporting to DWG all images are attached to the exported drawing as external references. This may be a problem with logotypes in the title block or other images.
In some projects you need to deliver your drawings without external references.
JTB Raster2OLE app for AutoCAD can help by binding all images in the current drawing or in multiple selected drawings. Free trial available.
