Proxy Graphics

I'm using AutoCAD R14.

I open a drawing done in 2000, but saved as R14, and I get a message
saying can not open Proxy Graphics, or to that effect. What exactly
are Proxy Graphics, and how do they affect a drawing?

Thanks.

 

A proxy object (or graphic) is a substitute for a custom object when the
ObjectARX application that created the custom object is not available to
AutoCAD or other host applications. Later, when the application is available
to AutoCAD, the proxy object is replaced by the custom object.

Proxy objects have significantly reduced capabilities compared to their
corresponding custom objects. The extent to which proxy objects can be
edited is determined by the parent ObjectARX application. For example,
operations such as erasing and moving an object, or changing object
properties, may or may not be possible on a proxy object, depending on the
application that created it.

When you open a drawing, you might see a Proxy Information dialog box. The
dialog box tells you the total number of proxy objects in the drawing (both
graphical and nongraphical) and the name of the missing application and
provides additional information about the proxy object type and display
state. You can use the dialog box to control the display of proxy object.
