In previous versions of MapleSim, you could connect a vector port (a port with more than one element) to a scalar port (a port with one element). Similarly, connections between a scalar port and a vector port were also allowed.

For example, connecting a Real Multiplexer component, which has a vector port with three elements, to the scalar input port of the Gain component was allowed (see the following figure).

This functionality caused confusion and lead to models that were difficult to debug. The ability to connect a vector port to a scalar port (as well as a scalar port to a vector) has been removed in MapleSim 6.2.

Older models that used this functionality can still be opened in MapleSim 6.2 and will still run. However, if you want to make a connection similar to the one shown in the preceding figure, you need to use an intervening component that converts a vector input to a scalar output, such as the Extractor component shown in the following figure.

For more information, see Connecting Vector and Scalar Components.

In previous versions of MapleSim, Ctrl+D (Command+D for Macintosh) was the hot-key combination used to show/hide probes in your model diagram. In MapleSim 6.2, this hot-key combination has been reassigned to the reroute connections command.
