A part is an electrical design primitive. It is a schematic symbol that represents an electronic device, such as a resistor, a switch, an operational amplifier, a voltage regulator, etc. Parts are stored within components in schematic component libraries. Note that each component can contain one or more parts. Along with a symbolic representation of the component, the part also includes links to models, such as the PCB footprint, and also parameters that are used to document details such as component parameters and supplier information. How the model links and parameters are added to the part depends on the type of library storage being used.
Parts are available for placement in both the schematic and schematic library editors.
The way in which a part is placed on a schematic sheet depends on how and from where placement mode is invoked.
In the schematic editor, the part selection and placement process is done from the Components panel.
If you cannot locate the required part in the Components panel, use the Search feature. To do this, click Search to open the File-based Libraries Search dialog.
A part also can be placed directly from a library that is open in the schematic library editor from the SCH Library panel. Note that:
In the schematic editor, the part selection and placement process is done from the Explorer panel. Click Place » Part to open the Explorer panel. Navigate to the desired part, right-click on the part then select Place. The selected part appears on the workspace with a crosshair. Click or Enter to place it.
Graphical editing for a part is limited to moving, rotating and mirroring. When a part is selected in the workspace, a dashed selection box will appear around it. To graphically manipulate a selected component:
The software includes tools to help work between the component on the schematic and that same component on the PCB. These tools include Cross Probing, Cross Selection, and Selecting the PCB Components from the schematic.
As the name implies, Cross Probe allows you to click on a component in one editor and jump to that component in the other editor. To Cross Probe:
Cross Select Mode selects the same component in the other editor. Note that it does not zoom and center. Cross Selection is either on or off. Click Tools » Cross Select Mode to toggle the mode on/off. Select multiple components by holding the Shift key as you click to select.
This feature allows you to select multiple schematic components in a specific order, then place those same components in the PCB editor in the same order. To use this feature:
Properties page: Part Properties
This method of editing uses the associated Properties panel mode to modify the properties of a part object.
During placement, the Component mode of the Properties panel can be accessed by pressing the Tab key.
After placement, the Component mode of the Properties panel can be accessed in one of the following ways:
The Properties panel supports multiple object editing, where the property settings that are identical in all currently selected objects may be modified. When multiples of the same object type are selected manually, via the Find Similar Objects dialog or through a Filter or List panel, a Properties panel field entry that is not shown as an asterisk (
*) may be edited for all selected objects.
A List panel allows you to display design objects from one or more documents in tabular format enabling quick inspection and modification of object attributes. Used in conjunction with appropriate filtering - by using the applicable Filter panel, or the Find Similar Objects dialog - it enables the display of just those objects falling under the scope of the active filter – allowing you to target and edit multiple design objects with greater accuracy and efficiency.
