ArcGIS for AutoCAD 250 and Other New Stuff
…ArcGIS for AutoCAD 250 is something brand new. It supports 64 bit and 32 bit AutoCAD versions 2010 and 2011 (likely 2012 when it ships). I really like using it with its new ribbon interface, better map image quality and performance. It supports connecting to more kinds of servers with certain forms of authentification and now supports ArcGIS Server fast maps. ArcGIS for AutoCAD 250 has a clever new set of selection tools that have been added. Performance when editing large amounts of attribute information is also greatly improved.
I like the quick access to Esri Maps on the Ribbon. I also like that I get to use AutoCAD 2011 and its clever entity cloning feature (Add Selected) that is especially useful when creating new features. However, my favorite AutoCAD 2011 enhancement, layer transparency, enables me to create composite maps in ArcGIS for AutoCAD from multiple map service sources, and create watermark style images that won't overpower the AutoCAD entities I’m working with while still allowing me to see and use my GIS maps.
