I installed acad2000 by custormed ,and I choosed all the items.When I
run cad,I cannot see the menu of the express,so I load it from
Tools/Menu Groups,and insert to the Menu Bar.After that,I can see them
on the menu,but when I use them,they will display an unknown command.I
tried to type the EXPRESSTOOLS,but they displayed it is an unknown
command.What can I do?
