When the Runtime Extension application that created the custom object is not available to ZWCAD or other host applications, a proxy object is used as a substitute for a custom object. Later, the custom object replaces the proxy object if the application is available to ZWCAD.
As compared to corresponding custom objects, Proxy objects are endowed with significantly reduced capabilities. The extent to which proxy objects can be edited is determined by the parent Runtime Extension application. For example, to determine whether to erase and move an object, or change object properties, may or may not be possible on a proxy object, depending on the application that created it.
A Proxy Information dialog box will be displayed when you open a drawing. Which shows 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 control the display of proxy objects with the dialog box.
