User enters the overall rough width and height of the opening together with the desired number of door panels (any number from 2 and up) and the model automatically calculates all necessary sizing.
The panels opening are controlled through an angle parameter. 0 degrees angle completely closes the door and 90 degrees angle folds the panel to the fully open position.
The thickness of the door panels is also one of the parameters controlled by the user.
User selects from an ON/OFF option whether to have a door frame around the opening or not. Parameters are available to control the frame thickness and the architrave width. Depending on whether the door frame is on or off, the clear door opening is calculated automatically.
