To Work With Shield Symbols

Insert Shield Symbols

1. Click Schematic tab Insert Components panelInsert Components drop-downIcon Menu. Find
2. On the Insert Component dialog box, click the Miscellaneous button.
3. Click the Shields button.
4. Select the type of shield to insert into the drawing.
5. Pick the points on each wire for the shield/cable marker and right-click to end the selection. The shield inserts into the drawing.

   If you chose to insert a cable marker with a shield, the standard Insert/Edit Cable Marker dialog box displays.

Note: Each successive symbol is automatically related to the parent (the top/left-most wire) as it is inserted.

Add a Second Shield to a Cable/Shield Representation

You can add a second shield representation to an existing set of cable/shield markers.

1. Click Schematic tabInsert Wires/Wire Numbers panelCable Markers drop-downCable Markers. Find
2. Select to Add 2nd Shield.
3. Select an existing shield marker (either select the first or last cable/marker shield symbol).
4. Specify the insertion point and right-click to end the selection.

Custom Shield Symbols

A special command, “wd_cblshld_bld {type}”, is used to insert the shield symbols and connecting lines. The {type} parameter indicates which library symbols to use to generate the shield and whether to cross the connecting lines or not. There are three symbols that are used to generate the cable shield, a top (HW01_#), middle (HW02_#B), and bottom (HW02_#) symbol. The “#” indicates whether the connecting lines should cross or not. A “1” results in straight connecting lines, and a “2” results in crossing connecting lines.

You can create you own custom top and bottom shield symbols by copying the existing symbols and adding a suffix to the symbol names after the “_#”. For example, a new top shield symbol might be called HW01_1U, and the corresponding bottom symbol, HW02_1U. Modify the symbols to meet your needs. In the icon menu add a new command option calling “wd_cblshld_bld 1P”.

Note: The same middle shield symbol can be used for all types.
