Line

Draw standard lines using AutoCAD’s standard LINE command.

Please note that a standard LINE located in an electric layer serves perfectly as an electric connection in cadett ELSA.

Xline

The cadett ELSA Xline command is an intelligent Line command. It can detect if you connect to a symbol, to another line, to the end of a line or similar. When needed the command inserts a connection point (a donut) and stops the sequence of lines to make it possible for you to begin a new sequence. In other words, this is a line command, which is as well suited to draw electrical circuit diagrams as one could desire. It therefore comes as no surprise that the Xline command is the most commonly used when drawing lines in cadett ELSA, at least when multiple phases are not involved.

Xline without donut

The commonly used Xline command places connection points in all “T-junctions”. According to the IEC standard, this is not incorrect, but not the preferred way of drawing either. To draw T-junctions without any connection points is.

The Xline without donut command works in exactly the same way as the Xline command, with the difference that no connection points are inserted.

3 phases

Multiline with 3 phases 5 mm apart.

Donut

The Donut command inserts a connection point. You can use it if you for example have used the Line command to draw two lines forming a “T”. If you had used Xline instead, a donut would have been automatically inserted. Accordingly, this is not the case if you use Line, but you can put the donut in place afterwards using the Donut command. The result will be exactly the same.

Electrically the connection point has no effect in a “T-junction”, since the lines are connected to each other anyway. A connection point in a four-way junction though, makes all the difference in the world. That is however the only situation where a connection point really matters.
