I have a PNG of building plans that I will need to digitize in AutoCAD Map3D. I have georeferenced the PNG in ArcGIS, which has produced a world file (.pgwx) in the same directory in which the image is stored. When I attempt to bring this image into AutoCAD using either Insert Image or Data Connect, I am prompted to specify an insertion point. It is clearly not recognizing the resource file. How can I open a georeferenced PNG in AutoCAD Map3D in the correct location?

reaname world file to .pgw from .pnwx. keep both image and world in same directory with same name.

This worked. Do you know why the world file extension must be changed? Does this occur with other raster formats? – Jyler Aug 19 '14 at 18:57
Arcgis is product of ESRI and autocad map is of autodesk. both are coded/designed to read different world file extension.e.g if your image is jpg file will be jgw in autocad and jgwx will be in arcgis suit. – GIS Data Butcher Aug 19 '14 at 19:05
Is it safe to say then that there is no standard world file format? – Jyler Aug 19 '14 at 21:49
