Proxy Objects
A proxy object is a substitute for a custom object when the ObjectARX appli-
cation 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 cor-
responding 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 cre-
ated 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 objects.
Object Enablers
An object enabler is a tool that provides specific viewing and standard editing
access to a custom object in AutoCAD or other host applications when the
ObjectARX application that created the custom object is not present.
Object Enablers allow custom objects in a drawing to behave with more intel-
ligence than proxy graphics. Object enablers also facilitate workgroup collab-
oration when using AutoCAD, AutoCAD LT, Volo View 3, and 3D Studio
Max.
If the ObjectARX application is not installed on your system, AutoCAD can
check for available Object Enablers on the Web. For example, if you receive
a drawing that contains objects that were created in AutoCAD Architectural
Desktop, but you don’t have that application installed on your system,
AutoCAD downloads the AEC Object Enabler so you can view those drawings
as they were intended. To control whether AutoCAD checks for Object
Enablers, use the Live Enabler settings on the System tab of the Options dia-
log box.
