prop_door_rotating / door_left alignment

It is a huge pain to align prop_door_rotating with the door_left model to the grid… seems pretty much impossible to get it exact, it also has some weird lighting going on (it’s dark. it’s just dark-colored for some reason.) even after I spent about 15 minutes getting even only one door aligned and making the space for it. It just takes a ridiculously long amount of time. What could I do to make it take, instead of 15 minutes, how about 1 minute or less to add a door? Any faster way to make a perfect easy door?

select the door in one of the grid views, right-click on snap to grid.

make sure you’re on the 1 grid and you can align it perfectly.
