Questions and Answers - Summer 2004


Question: I'm running a Dynamic DC analysis on my schematic. When I enable multiple displays such as voltage, current, and power, the schematic can start to get cluttered. Is there a way to suppress some of the display elements?

Answer: The voltage displays can not be suppressed. These are assigned to the individual nodes and can not be disabled. However, the current, power, and condition displays are all assigned to individual components and may be enabled/disabled within the Attribute dialog box. Double click on a component while in Select mode and the Attribute dialog box will be invoked. Near the top of the dialog box there is a Display section. In this section, there are Current, Power, and Condition options which determine whether the corresponding schematic display for the component will appear on the schematic when that display type is called for. These options control the display status for both Dynamic DC and Dynamic AC analyses.

There is a method available for changing the display settings of multiple components of the same type easily. For example, if you want the power display to be disabled for all batteries, double click on one of the batteries. Disable the Power option in the Display section. Hit OK. With the battery still selected, go to the Edit menu and select Change. In the Change menu, there is a command that will appear similar to:

Apply Display Properties of part_name to all part_types...

where part_name is the PART attribute of the selected component and part_types is the component type of the selected component. This command invokes a dialog box that lets you copy the settings of the component's Attribute display properties, color and font, and/or Display options to all other components of the same part type. In this case, only the Display options would need to be enabled. When OK is clicked, the Display settings of the selected battery would be copied to all other batteries in the schematic. This command does copy the settings for all six available display options to every other battery, so you do want to be careful if you have customized individual components already.
