Modifying a Grid or Surface

In AN-SOF, wire grids and solid surfaces are treated as collections of individual wires or strips. Once created, they cannot be re-opened in the original “Draw” dialog box. Instead, you use Massive Edition tools to adjust the entire structure at once.

Selecting the Structure

To modify a grid or surface, you must first select the components you want to change:

• The Selection Box: Click the Selection Box button on the main toolbar.
• Draw the Box: Left-click and drag in the workspace to encompass the grid or surface. Selected wires will turn light blue (see Fig. 1).

Executing Modifications

Once your selection is highlighted, you can access the modification tools:

• The Modify Command: Go to Edit > Modify, use the shortcut Ctrl + M, or click the Modify button on the toolbar.
• Scope of Changes: This opens a dialog box where you can update the Cross-Section, Resistivity, or Coating for all selected wires simultaneously.
• Refer to: Selecting and Modifying Multiple Wires

Advanced Manipulations

If you need to change the physical orientation or duplicate the structure, use the following specialized commands:

• Move, Rotate, & Scale: Used to reposition a grid (e.g., moving a reflector behind a dipole) or resize it for a different frequency band.
• Copy & Stack: Useful for repeating a grid pattern across an array.
