Many changes, scattered throughout the package, make it easier to track down and reuse pieces of projects. In fact, AutoCAD 2000 encourages users to do just that. A source drawing can be on a local machine, network, or on the Internet, and can be dragged into an open drawing. You can also move from drawing to drawing without canceling a command. AutoCAD 2000 can translate R14 files complete with custom multiline styles, custom menus, and toolbars in the newer version.
Individual dealers can provide information about incompatibilities.
Drafting All this aside, the key reason architects buy drafting packages is for, well, drafting. The automatic snapping to add features to existing geometry is already in AutoCAD 14. New geometry snaps to old in an intelligent manner. This has been enhanced with extra construction lines that can appear on the drawing to help guide placement of new items. The amount of text associated with professional-drawing sets has been increasing rapidly.
