I already assigned L as line command. but if I press L nothing happens. need help. thanks
Some keys has already used in Catia. If you push normal keys (like w, s, h, etc.) you will type them in command line. So nothing happens. You have to deactivate command line to use only single key for one command. I don't know how it will deactivate without Altgr. But altgr key is doing this. And if you combine key with Altgr everthing is ok :)
If you find a way to deactivate command line or another way to do this, please notify me.
