Arc
Parent page: PCB Dialogs
The Arc Dialog.
Summary
This dialog allows the designer to specify the properties of an Arc object. An Arc is a primitive design object, used to create curved shapes on a single layer of a PCB. This could include: curved corners in the routing, a circular ring on the component overlay, or a curved edge on a keepout zone.
Access
The dialog can be accessed during Arc placement:
- By pressing the Tab key.
After placement, the dialog can be accessed in the following ways:
- Double-clicking on an Arc object.
- Placing the cursor over an Arc, right-clicking and selecting the Properties command from the context menu.
Options/Controls
- Radius - The radius of the Arc, measured from the center point, to the center of the Arc line.
- Width - The width of Arc line.
- Start Angle - The start angle of the Arc, measured from the X axis in the first quadrant (plane geometry).
- End Angle - The end angle of the Arc.
- Center X/Y - The X/Y location of the Arc center.
Properties
- Layer - The layer that the Arc is placed on. Arcs can be placed on any layer other than the system layers.
- Locked - Lock the object so that it cannot be edited graphically. A locked object cannot be selected or edited.
- Net - If the Arc is a copper object, choose a Net for the Arc. All Nets in the current project will be listed in the drop-down list.
-
Keepout - Check this box to set the Arc object to act as a Keepout object. A Keepout object is displayed in the layer color, outlined in the Keepout color. A keepout object is used on a signal layer to create a layer-specific keepout. Layer-specific keepouts are not included during output generation.
