Definition/modification of openings

Using the Opening definition dialog, you can define or modify an opening for a predefined opening type (such as windows and doors):

	Rectangular opening	H = height B = width
	Round opening	D = diameter
	Pentagon-shaped opening	h, H = heights B = width
	Arc-shaped opening	h, H = heights B = width
	Section of an arbitrary shape: Define - in the drawing area, click to specify points that define the opening shape. Select - in the drawing area, select a polyline (created with AutoCAD®) that forms a closed contour.

To add a new opening to the list of openings available in Autodesk AutoCAD Structural Detailing - Formwork Drawings:

1. Click an opening type icon
2. For Name, enter the opening name
3. Specify the opening dimensions
4. Click OK.

When defining an arbitrarily-shaped section, specify the name of the opening, and click either Define or Select.
