Elliptical Arc

The Elliptical Arc dialog.

Summary

This dialog allows the designer to specify the properties of an Elliptical Arc object. An elliptical arc is a non-electrical drawing primitive. It is essentially an open circular or elliptical curve that can be placed on a schematic sheet.

Access

The Elliptical Arc dialog can be accessed prior to entering placement mode, from the Schematic – Default Primitives page of the Preferences dialog. This allows the default properties for the elliptical arc object to be changed, which will be applied when placing subsequent elliptical arcs.

During placement, the dialog can be accessed by pressing the Tab key.

After placement, the dialog can be accessed in one of the following ways:

• Double-clicking on the placed elliptical arc object.
• Placing the cursor over the elliptical arc object, right-clicking and choosing Properties from the context menu.
• Using the Edit » Change command and clicking once over the placed elliptical arc object.

Options/Controls

• Line Width - the width of the arc line. Available widths are: Smallest, Small, Medium, and Large.
• X-Radius - the radius of the arc in the horizontal plane (Y = 0), measured from its center point, to the center of the arc line.
• Y-Radius - the radius of the arc in the vertical plane (X = 0), measured from its center point, to the center of the arc line.
• Start Angle - the start angle of the arc, in degrees from the horizontal.
• End Angle - the end angle of the arc, in degrees from the horizontal.

• Color - click the color sample to change the color of the arc, using the standard Choose Color dialog.
• Location X/Y - the current X (horizontal) and Y (vertical) coordinates for the center point of the arc. Edit these values to change the position of the arc in the horizontal and/or vertical planes respectively.
• Locked - enable this option to protect the arc from being edited graphically.
