Garage Door Lift Mechanisms

This Demonstration models two up-and-over garage door mechanisms. The retractable door type (red) opens with minimal lost space inside the garage, but protrudes about one-third outside the door frame. The canopy door (blue) takes more space inside when opening but opens flush with the outside wall.
Move the counterweight on the right up and down to compare the two different mechanisms.
