The Arc dialog

Summary

The Arc dialog provides controls to specify the properties of an Arc object. An Arc is a primitive design object that is 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-click on an Arc object.
• Place the cursor over an Arc, right-click then select 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 on which the Arc is placed. Arcs can be placed on any layer other than the system layers.
• Locked - Enable to 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 and is 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.
