Issue:
When right-clicking an object in AutoCAD, the shortcut menu does not show the correct commands for the object.
Causes:
Object specific commands only appear in the context menu when the PICKFIRST variable is set to 1. The PICKFIRST variable controls whether or not you can select an object and then execute a command on it.
Solution:
Revert the PICKFIRST variable. On the command line in AutoCAD, type PICKFIRST and change the value to 1.
