Channel

The Channel tool and Channel - 3D tool share the same position on the tool set. Click and hold the mouse on the visible tool to open the Pop-out tools list and select the desired tool.

2.Click to place the object in the drawing, and click again to set the rotation. The first time you use the tool in a file, a properties dialog box opens. Set the default parameters. The parameters can be edited later from the Object Info palette.

Parameter	Description
Series	Select the desired series to display the appropriate nominal sizes
Size	Select the channel size
Draw Free Height Lines	Select whether to draw the 2D channel with free height lines
Place Locus at Centroid	Select whether to draw a locus at the centroid of the 2D channel
Lock Centroid Position	Locks the centroid position; when locked, the centroid behaves like the object’s insertion point and remains in position if the object’s shape/size/rotation is edited
Length (Design Series required)	Enter the length of the 3D channel
Custom Size	Select this option to enable fields for specifying a custom channel size
Depth	Displays the depth between endpoints, or if Custom Size is selected, allows entry of a custom value
Flange Width	Displays the flange width, or if Custom Size is selected, allows entry of a custom value
Flange Thickness	Displays the flange thickness, or if Custom Size is selected, allows entry of a custom value
Flange Angle (Deg.)	Displays the flange angle degrees, or if Custom Size is selected, allows entry of a custom value
Web Thickness	Displays the web thickness of the channel, or if Custom Size is selected, allows entry of a custom value
Toe Radius	Displays the toe radius value, or if Custom Size is selected, allows entry of a custom value
Fillet Radius	Displays the fillet radius value, or if Custom Size is selected, allows entry of a custom value
Section Properties	Section properties are automatically calculated and displayed based on inch units for imperial shapes and millimeter units for metric shapes (regardless of the units selected and Show Unit Mark setting in the Units dialog box)
Area	Displays the channel area
About Axis X-X/Y-Y
Moment of Inertia	Displays the moment of inertia about both the horizontal (X-X) and vertical (Y-Y) centroidal axes
Section Modulus	Displays the section modulus about both the horizontal (X-X) and vertical (Y-Y) centroidal axes
Radius of Gyration	Displays the radius of gyration about both the horizontal (X-X) and vertical (Y-Y) centroidal axes
