In Chief Architect X6 and prior, when I add two switches to my drawing, and then connect them to a single light, my switches convert automatically to three-way switches. How do I stop this automatic conversion process, so that I only have the two-way switches I started out with?
By default in X6, electrical switches are set to automatically change to three-way switches when more than one switch is connected to the same fixture.
If you would prefer that the program not do this, you can turn off this behavior for any electrical switch in its specification dialog. It is important that this be done before electrical connections are drawn to the switch in question, however, as once a switch has been converted to a 3-way switch, there is not a way to convert it back.
