Adding an Isolated Footing

From the Shape option, choose the isolated footing shape.

Complete the isolated footing dimensions.

To position the isolated footing on a grid, click Position on Grid

.

To position the isolated footing on a wire, click Position on Wire

and select one or more wires.

To create an isolated footing in a new geometrical set, select the Create in a new geometrical set check box.

To specify the footing location, in the Isolated Footing dialog box, from Create Mode, click one of the following:

Option	Description
Single	Inserts a single isolated footing on the selected segment.
Along gridline	Inserts isolated footings along the gridline of the selected segments.
All in story	Inserts isolated footings at the bottom of all internal column locations in the structural grid.

To change the grid segment that defines the zero angle orientation for the isolated footing, in the Isolated Footing dialog box, click either of the following:

Snap Rotation
Snap Rotation

In the Rotation box, specify the required rotation angle to rotate the footing counterclockwise about its length.

To change the isolated footing default characteristics, expand Options.

If you position the footing on a wire, perform the following steps:

U Offset, specify the required offset for the X coordinate.
V Offset, specify the required offset for the Y coordinate.
Vertical Offset, specify the required offset value for the Z coordinate.

If you position the footing on a grid, perform the following steps:

U Offset, specify the required offset to translate the footing in the U direction.
V Offset, specify the required offset to translate the footing in the V direction.
Vertical Offset, specify the required offset value to translate the footing in the vertical direction.

If you position the footing on a grid, expand Grid Segement Display and in the Grids to Display box, specify the grid segments and grid points.

In the 3D area, click a point on the structural grid where you want to place an isolated footing.

Click OK.
