Configuring Symbol Creator Tool Settings

PartQuest Portal Subscription: Essential or Professional

The Symbol Creator tool enables you to create a custom symbol for a PartQuest Portal part. Prior to using the Symbol Creator tool you need to set basic characteristics of your symbol such as the layout and size of the symbol graphics and text, and graphic annotations that are applied to terminals(pins).

Table 1. Symbol Creator Tool Settings

Setting

Description

Unit

Defines the unit for all measurements on the symbol.

Grid Size

Defines the grid size.

Property Texts

Controls visible property text position and size.

Terminal(Pin) Display

Terminal(Pin) Spacing

Defines the spacing between terminals. This setting determines the general size of your symbol. The terminal names, terminal numbers, and other graphical characteristics are sized relative to the terminal spacing. You should always choose a terminal(pin) spacing that is equal to, or a multiple of, the schematic grid you are using.

Graphic Annotations

Optionally enable graphic annotations on your symbol as defined by the IEEE ANSI drafting standards.

Terminal(Pin) Display Property Name

Enables you to change the name of the terminal property used to display the terminal(pin) name. The default terminal property is PinLabel.

The PartQuest Symbol Creator tool enables you to use duplicate terminal(pin) names, and these names display on the resulting symbol as duplicates; however, each duplicate entry uses a hidden label with a suffix of __x where “x” is a number starting at 0 and incrementing by 1 for each duplicate terminal name on the same symbol.

The tool adds the displayed name as a property of the terminal(pin). By default, the name of this property is “PinLabel.” For example, you may have 3 terminals that are all GND, and you want to see GND. You can specify these as GND, and PartQuest uses “PinLabel,” or whatever property you provide, to label each terminal with GND for display on the symbol. The actual terminal(pin) names are GND__0, GND__1, GND__2.

Prerequisites

Procedure

  1. Open the Symbol Creator Settings page by doing one of the following:

    If you want to...

    Do the following...

    Open the settings page from your profile page

    1. Visit your PartQuest Portal profile page by choosing the Welcome {your_name} > My Profile menu item.

    2. Scroll to the Custom Symbols section.

      Note:

      From the Custom Symbols section you can get more information about symbol graphics by doing the following:

      • Download the “IEEE Standard - Std 315-1975 Graphic Symbols for Electrical and Electronics Diagrams” document.
      • Go to the IEC Webstore to purchase the “IEC Standard - 60617:2012 DB Graphical Symbols for Diagrams” document.
    3. In the Symbol Creator subsection, click the Settings button.

    Open the settings page from the Symbol Creator page

    1. Display a list of parts from either a search, the Favorites page, or a project page. See Searching for Parts, Saving and Accessing Favorite Parts, or Viewing and Managing Projects.

    2. From a part list, expand one of the part descriptions by clicking the More button.

    3. Click the Choose Symbol button.

    4. From the Choose Symbol window, click the Create Symbol (+) button.

    5. On the Symbol Creator page, click the Settings button.

    The Symbol Creator Settings page displays.

  2. In the Unit section, do the following:

    If you want to...

    Do the following...

    Set the grid size unit

    From the Unit dropdown list, choose one of: Inches, Centimeters, or Millimeters.

    You should choose the unit that matches the unit you use in your schematic capture tool so that the symbol more easily aligns with the schematic grid during placement.

    Set the grid size

    In the Grid Size field, type a numeric value. A valid value range is provided under the Grid Size field.

    Restore the section to the default settings

    At the bottom of the section, click the Reset All to Defaults button.

  3. In the Property Texts section, do any of the following:

    If you want to...

    Do the following...

    Add a new property to the visibility list

    1. Click the add (+) button.

    2. Type a value in the text field and press Return.

    Note:

    Property settings only apply to your symbol if the property is present on the symbol. Properties come from the supplier, which you can map to your preferred property names using property mapping. See Mapping Digi-Key Property Names.

    Remove an existing property from the visibility list

    1. Double-click the property tab you wish to remove from the visibility list.

      Note:

      You can not delete the default REFDES tab.

      The text highlights in the text field.

    2. With the property text highlighted, press Delete or Backspace.

    3. With the text field empty, press Return.

    Set the location of the text relative to the symbol body

    1. Click a property tab to select it.

    2. In the Location page, click one of the positions: Top, Bottom, Left, or Right.

    Set the Font size of the text

    In the Font Size text field, do one of the following:

    • Specify the text size as “Automatic”.

      This setting causes the Symbol Creator tool to scale the text size relative to the size of the terminal (pin) spacing you choose.

    • Enter a numeric value.

    Restore the section to the default settings

    At the bottom of the section, click the Reset All to Defaults button.

  4. In the Terminal(Pin) Display section, do any of the following:

    If you want to...

    Do the following...

    Specify the Terminal(Pin) spacing

    In the Grid field, specify the spacing between two or more terminals on the same side of the symbol by typing a numeric value representing grid units.

    For example, if your Grid Size is set to 0.01 inches, then setting the spacing at 2 grid units would create a terminal(pin) spacing of 0.02 inches.

    Enable/disable graphic annotations on your symbol

    In the “Show graphic for” section, set the corresponding property to “Yes” to enable the generation of that graphic for any terminal that has that property defined.

    Change the name of the terminal property used to display the terminal(pin) name

    In the Terminal(Pin) Pin Display Property Name section, select the existing text (PinLabel is the default) and type the new value.

    Restore the section to the default settings

    At the bottom of the section, click the Reset All to Defaults button.

  5. After you have changed settings on the Symbol Creator Settings page, do any of the following:

    If you want to...

    Do the following...

    Restore the entire page to the default settings

    At the bottom of the page, click the Reset All to Defaults button.

    Discard changes and return to the Symbol Creator

    At the bottom of the page, click the Discard Changes button.

    Save your changes

    At the bottom of the page, click the Save and Exit button.

    The changes are saved and you are redirected to either your profile page or to the Symbol Creator page, depending on where you started.
