Here is how it works... the door only moves as far as it is thick/long/wide... depending on which angle you set it to move. We will be faking the vertical size with a invisible brush.

Once you have your elevator constructed and the fake height brush, highlight them all and add the door function.

Give it a -1 angle by hitting the "U" button since it's going up.

You can set the speed then make it wait on top with the key: wait, value: 3 (secs).

Change the sounds or use the wood default or metal "doortype".
