Selecting and Modifying Multiple Wires

AN-SOF allows you to simultaneously edit a group of wires. There are three ways to select multiple wires for editing:

1. Using the Selection Box Tool: Drag a rectangular box to select multiple wires.
2. Selecting Wire by Wire: Left-click on individual wires while holding the Ctrl key.
3. Combination of Both Methods: Use a mix of the Selection Box tool and wire-by-wire selection.

Using the Selection Box Tool

1. Click the Selection Box button on the main toolbar.
2. Left-click on the workspace and drag a box to select multiple wires (see Fig. 1).
   • All wires within the selection box will be highlighted in light blue.
   • Dragging the box from top to bottom selects only fully enclosed wires.
   • Dragging the box from bottom to top selects partially enclosed wires as well.
3. To deselect all wires, double-click on the screen or click the Home button in the toolbar.

Selecting Wire by Wire

1. Click the Select Wire button (arrow icon) on the main toolbar.
2. Hold the Ctrl key and left-click on individual wires to select them.
   • To deselect a wire, hold the Ctrl key and click on it again.
3. To deselect all wires, double-click on the screen or click the Home button in the toolbar.

Modifying the Selected Wires

Once multiple wires have been selected, navigate to Edit > Modify in the main menu to modify them. The Modify command opens a dialog box (see Fig. 2) with three tabs: Attributes, Materials, and Sources/Loads. Use the checkboxes to specify which parameters you want to modify.

In the Attributes tab, the Segments per Wire and Segments per Wavelength options allow for bulk editing of wire segments. These options are mutually exclusive:

• Segments per Wire sets a fixed number of segments for all selected wires.
• Segments per Wavelength sets the number of segments for each wire based on its length in wavelengths, using the shortest wavelength corresponding to the highest frequency specified.

Entering “0” (zero) in the Segments per Wire field will automatically set the number of segments for each wire based on 10 segments per wavelength.

In the Sources/Loads tab, you can remove sources and loads in bulk by selecting “Delete Sources” or “Delete Loads”.
