Door basics

To change the dimensions of a door, select the Frame and then change the Width and Height. (You can also select Door Leaf and then change the Width and Height Between Centre Lines.)
To remove the frame (i.e. when just quoting for new door leaves), select the Item and then untick New Frame.
To change how door is hung, select the Door Leaf and then click one of the options along the bottom.
To change whether the door opens inwards or outwards, select the Door Leaf and then click the option next to Door Type. After choosing an option, you can either apply the change to all door leaves in the drawing, or to the selected leaf only.
To change a single door to a pair of French doors or a stable door, select the Door Leaf, then click Change... in the bottom right and choose the relevant option.
