Eznec

Entering or changing wire coordinates Note that all wires are straight, extending from one end coordinate to the other. If two wires have the same end coordinates they're considered to be connected. (They are also considered connected if their end coordinates are within 1/1000 segment length.) If a ground is specified and a wire end has a z coordinate of zero (or within 1/1000 segment length of zero), the end is considered to be connected to ground. The NEC-2 code in EZNEC will also connect wires whose segment junctions coincide. However, I strongly discourage you from taking advantage of this. First, EZNEC won't show you that they're connected. Second, the connection will be broken if you change the length or number of segments of either wire, leaving the wires crossing. Wires which cross or coincide can result in major inaccuracies, so this situation should be avoided.

Connect wires only at their ends. If a ground is specified, a wire end will be considered connected if the z coordinate is within 1/1000 segment length of zero. If the z coordinate of any wire is more negative than -1/1000 segment length, an error message will result if a ground plane is specified. Wires with both coordinates within 1/1000 segment length of ground, or within a wire radius of ground, will be considered to be lying on the ground and will cause an error message.

To enter or change wire coordinates, simply type the wire number. (<RET> is required following the number only if there are more than nine wires.) This will highlight end 1 of the selected wire. To move to end 2, press the right cursor arrow key. Wire coordinates can be entered in two different ways.

Either may be used as desired: 1. Conventional. Just enter the x, y, and z coordinates when prompted, separating them with commas. IF YOU NEED TO CHANGE ONLY ONE OR TWO COORDINATES, IT'S NOT NECESSARY TO REENTER ALL THREE. Simply leave unchanged coordinates blank. For example, to change coordinates 3.75,4.95,.713 to 3.85,4.95,.713 you only need to type '3.85,,'. This shortcut also works in the Group Edit mode, so you can change only one or two coordinates of a group of wires if desired.

2. As connections to other wires. To connect a wire end to another wire end, type 'W#E#' for "Wire number End number". For example, to connect an end to wire 3, end 1, type 'W3E1' at the prompt for coordinates. The correct 81
