The IEEE Symbol dialog.


This dialog allows the designer to specify the properties of an IEEE Symbol object. IEEE symbols are non-electrical drawing primitives. They are used for representing logic functions or devices. These symbols enable users to understand the logic characteristics of these functions or devices without requiring specific knowledge of their internal characteristics.

For information on how a placed IEEE symbol object can be modified graphically, directly in the workspace, see Graphical Editing.


The IEEE Symbol dialog can be accessed during placement by pressing the Tab key.

After placement, the dialog can be accessed in one of the following ways:

  • Double-clicking on the placed IEEE symbol object.
  • Placing the cursor over the IEEE symbol object, right-clicking and choosing Properties from the context menu.


  • Symbol - this field defines the graphical IEEE symbol. Select a symbol from the drop-down list.
  • X/Y-Location - the current X (horizontal) and Y (vertical) coordinates for the location of the symbol. Edit these values to change the position of the symbol in the horizontal and/or vertical planes respectively.
  • Size - the current size of the IEEE symbol. The default size is 10 DXP Default Units (100mil). Increase or decrease this value to make the symbol bigger or smaller respectively. Entering a negative value results in the symbol appearing as if rotated by 180 degrees.
  • Orientation - specify the orientation of the symbol, counter-clockwise in relation to the horizontal. Options available are: 0 degrees, 90 degrees, 180 degrees, 270 degrees.
  • Mirrored - enable this option to have the symbol mirrored on the schematic (flipped along the Y-axis).
  • Locked - enable this option to protect the symbol from being edited graphically.
An object that has its Locked property enabled cannot be selected or graphically edited. Double click on the locked object directly and disable the Locked property, to graphically edit the object.
  • Line Width - the width of the line used to draw the outline of the symbol. Available widths are: Smallest, Small, Medium, and Large.
  • Color - click the color sample to change the color of the symbol, using the standard Choose Color dialog.
