I cant use the shortcut L to make a line or any other shortcut. There is nothing in my aliases. When i go in : User Preferences - Aliases, there is nothing. When i import them from : Program File - Dassault Systeme - Draftsight - Default Files - Alias, and take the alias file and import it, i see it. But when i apply it, it disappear. What should i do to get me default shortcut back ???
