Opening Type
Direction : Select a reference point to define opening size and position.
Distance
dx : Horizontal distance from the reference point to the near most edge of an opening
dy : Vertical distance from the reference point to the near most edge of an opening
Opening Size
w : Width of an opening
h : Height of an opening
Subdivide Frame Elements
If this option is selected, the line elements on the periphery of the wall element are divided according to the opening width.

Note
Once wall opening is defined, wall element will be vertically divided and additional beam elements are automatically generated at the top and bottom of the opening. If "Auto Constraint for Wall Elements Connectivity" option is checked on in Main Control Data, "Linear Constraint" will be automatically considered for the connectivity with the top and bottom of the connected elements.
