Properties Window
The Properties Window displays and enables editing of the attributes of signals, pins, symbols and their elements. To open the Properties window, use the Edit > ... Properties command, the 
button on the View Toolbar, or by right-clicking on the selected element and choosing ... Properties. Additionally, double-clicking the selected elements in the Symbol Window opens the Properties Window. The name of the menu command displaying the Properties window depends on the active window. For example, if the Signals List is active, the command is named Signal Properties.
The contents of the Properties Window depends on the active window and the current selection. If the Signals List is active, signal properties are displayed. If the Pins List is active, pin properties are displayed. If the Symbol Window is active, selected elements properties are displayed, or the attributes of the whole symbol when nothing is selected.
Some attributes displayed in the Properties window are read-only, for example, signal name for ports. Other attributes may be modified by double-clicking the attribute field on the right side of the Properties window. Some attributes are presented in groups, with a + sign to the left. For example, all attributes associated with displaying the Signal Name besides the port are in the Signal Name group.
In the Properties window, you can simultaneously change attributes for a group of selected items. For example, to change properties for several pins, select the pins, open the Properties window, and edit the desired attribute.
Any change made to an attribute will only be carried through to all elements supporting that attribute. For example, if ports are selected together with an arc, changing the Inverted attribute will set its new value for all selected ports, leaving the arc unchanged.
PADS I/O Designer interprets most of the symbol attributes internally. However, it is possible to add custom symbol attributes. To add a custom attribute, click on the right side of the Properties window next to the text New attribute, and type in the name of the new attribute. It will then appear on the list, and can be edited as other attributes. Custom attributes are generated in symbol and schematic files in the form of properties.
For each type of element, the following tables list all the attributes available in the Properties Window:
