Configuring PCB Rectangle Object Properties in Altium Designer

Parent page: Rectangle

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 – Rectangle 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 (accessed from the  button at the top-right of the design space). Select the object in the Primitive List to reveal its options on the right.

  • Post-placement settings – all Rectangle object properties are available for editing in the Rectangle dialog and the Properties panel when a placed Rectangle is selected in the design space.

 

If the Double Click Runs Interactive Properties option is disabled (default) on the PCB Editor - General page of the Preferences dialog, when the primitive is double-clicked, or you right-click on a selected primitive then choose Properties, the dialog will open. When the Double Click Runs Interactive Properties option is enabled, the Properties panel will open. 
While the options are the same in the dialog and the panel, the order and placement of the options may differ slightly. 

Location

The lock 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 rectangle, relative to the current design space origin. Edit to change the X position of the rectangle. 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 rectangle, relative to the current origin. Edit to change the Y position of the fill. The value can be entered in either metric or imperial, include the units when entering a value whose units are not the current default. 
  • Rotation - the rectangle's angle of rotation (in degrees), measured counterclockwise from zero (the 3 o'clock horizontal). Edit to change the rotation of the rectangle. The minimum angular resolution is 0.001°.

Properties

  • Corner Mode - use the drop-down to select the desired corner mode of the rectangle from the following options: 
    • Rectangle - specifies that the placed rectangle will have square corners. 
    • Fillet - specifies that the placed rectangle will have rounded corners. 
    • Chamfer - specifies that the placed rectangle will have sloped or angled corners. 
The corner mode can also be chosen during placement by pressing the Spacebar.
  • Track Width - displays the current width of the track. Edit this field to change the track width within the range 0.001mil to 10000mil.
  • Fillet/Chamfer Size - this is available only when Fillet or Chamfer is selected from the Corner Mode drop-down or if fillet or chamfer mode was chosen during placement.
  • Layer - the layer to which the rectangle is currently assigned. Rectangles can be assigned to any available layer. Use the drop-down to select a different layer.
  • Width - displays the (X-axis) width of the selected Rectangle.
  • Height - displays the (Y-axis) height of the selected Rectangle.
  •  - click this icon to retain the existing X to Y ratio of the rectangle.
