I have a drawing file of a map area in AutoCAD Map 2008 of a small resort/island. It is in true scale. I need to export these layers to .sdf. When I add the .sdf in MapGuide Author they do not show up. I did a test and created a polygon in the .dwg near 0,0 and it showed in the .sdf in Author. So what looks like going on is the bounding area within Author in not large enough. The test polygon I drew near 0,0 in the .dwg compared to the rest of polygons was the size of africa when I brought it into Author. Won't scaling down the .dwg cause the layers not to line up with the imagery correctly? Any advice would be appreciated!
