Configuring PCB Center Dimension Object Properties in Altium Designer

Parent page: Center Dimension

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 Center Dimension 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 workspace). Select Center Dimension in the Primitive List to reveal its options on the right.
• Post-placement settings – all Center Dimension object properties are available for editing in the Properties panel when a placed Center Dimension is selected in the workspace.

Properties

• Layer - the layer to which the dimension is currently assigned. Dimensions can be assigned to any available layer. Use the drop-down to select a different layer.
• Rotation (Properties panel only) - the angle of alignment of the dimension, measured counterclockwise in degrees from the horizontal.
•  Size -  the current length of the dimension's crosshair lines (or the diameter of the encompassing circle).
