Parent page: Arc Keepout

PCB Editor object properties are definable options that specify the visual style, content and behavior of the placed object. The property settings for each type of object are defined in two different ways:

  • Pre-placement settings – most Arc Keepout object properties, or those that can logically be pre-defined, are available as editable default settings on the PCB Editor - Defaults page of the Preferences dialog (access from the  button at the top-right of the workspace). Select the object in the Primitive List to reveal its options on the right.
  • Post-placement settings – all Arc Keepout object properties are available for editing in the Properties panel when a placed Arc Keepout is selected in the workspace.

        The Arc Keepout default settings in the Preferences dialog and the Keepout - Arc mode of the Properties panel.

In the below properties listing, options that are not available as default settings in the Preferences dialog are noted as "Properties panel only".

Location (Properties panel only) 

The  icon to the right of this region must be displayed as  (unlocked) in order to access the below fields. Toggle the lock/unlock icon to change its lock status.
  • (X/Y)
    • X (first field) - the current X (horizontal) coordinate of the reference point of the arc keepout, relative to the current workspace origin. Edit to change the X position of the arc keepout. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 
    • Y (second field) - The current Y (vertical) coordinate of the reference point of the arc keepout, relative to the current origin. Edit to change the Y position of the arc keepout. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 

Properties

  • Restricted for ​​Layer - use the drop-down to select the restricted layer.​​
  • Width - displays the current width of the arc keepout. Click to edit.
  • Radius - displays the radius of the arc keepout.
  • Start Angle - displays the start angle. Click to edit.
  • End Angle - displays the end angle. Click to edit.
Values can be defined in either mm or mil units. When entering a value in units other than the current units, add the mm or mil suffix to the value.

Keepout Restrictions

Use this region to select which object types will be restricted by the Keepout. Deselecting an object type will cause the Keepout to allow transgressions by that type of object (not kept out) by not imposing the applicable Clearance Rule. Choices include:

  • Via
  • Track
  • Copper - any object placed on a signal layer, or the multi-layer
  • SMD Pad - single-layer pad
  • TH Pad - thru-hole pad
