Procedure

You can share drawing files from AutoCAD and AutoCAD LT, drawing files from previous versions, and drawing files that contain custom objects. In some cases there are limitations.

Work with Drawings in Earlier Releases
When you work with drawings created in AutoCAD 2008 (and later releases) in AutoCAD 2007 (and earlier releases), you should be aware of the following visual fidelity issues.
Save Drawings to Previous Drawing File Formats
You can save a drawing in a format compatible with previous versions of the product.
Work with AutoCAD Drawings in AutoCAD LT
AutoCAD LT offers full compatibility when working with AutoCAD drawings. However, you should understand how AutoCAD LT handles AutoCAD-only features.
Work with Custom and Proxy Objects
Custom objects provide additional capabilities to the program and related products. When the application that created the custom object is not available, a proxy object is substituted in its place.
