Driver commands
Hi sammyb128,
After you download a command you have to enable it. Go to edit session (top left drop down menu) L click edit session then select add scroll down the list of commands till you find the door control command then L click on it. Go back to edit session select edit scroll down the list again and L click on the command which will put a green tick in the box beside it. It will then be available in surveyor.
Hope this helps,
