The No ERC dialog.


This dialog allows the designer to specify the properties of a No ERC object. The No ERC marker is placed on a node in the circuit to suppress all reported warning and/or error violation conditions that are detected when the schematic project is compiled. Use this to deliberately limit error checking at a certain point in the circuit that you know will generate a warning (such as an unconnected pin), while still performing a comprehensive check of the rest of the circuit.

The No ERC marker cannot be modified graphically, other than changing its location. To move a No ERC marker, click and hold while dragging it to a new location.


The No ERC 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 No ERC object.
  • Placing the cursor over the No ERC object, right-clicking and choosing Properties from the context menu.


  • Orientation - specify the orientation of the marker, counter-clockwise in relation to the horizontal. Options available are: 0 degrees, 90 degrees, 180 degrees, 270 degrees.
  • Symbol - specify which symbol to use for the marker. The No ERC marker supports a number of different styles, and can be displayed in any color. Use this ability to reflect the design intent for this point in the circuit. Supported symbols are: Thin Cross, Thick Cross, Small Cross, Check Box, and Triangle.
  • Color - click the color sample to change the color of the marker, using the standard Choose Color dialog.
  • Location X/Y - the current X (horizontal) and Y (vertical) coordinates for the center point of the marker's bounding rectangle. Edit these values to change the position of the marker in the horizontal and/or vertical planes respectively.
  • Locked - enable this option to protect the marker 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.
