Definition/modification of a cross-section

Using the Section definition dialog, you can define or modify a section for a predefined section type:

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

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

1. Click a cross-section type icon
2. For Name, enter the section name
3. Specify the cross-section dimensions
4. Click OK.

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