The Elliptical Arc dialog

Summary

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

For information on how a placed elliptical arc object can be modified graphically directly in the workspace, see Graphical Editing.

Access

The Elliptical Arc dialog can be accessed during placement by pressing the Tab key.

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

  • Double-click on the placed elliptical arc object.
  • Place the cursor over the elliptical arc object, right-click then choose Properties from the context menu.

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.
The arc is drawn in a counterclockwise direction from the Start Angle to the End Angle. Enter a value between -360 and 360 for each of these angles.
  • 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.
An object that has its Locked property enabled cannot be selected or graphically edited. Double-click on the locked object directly then disable the Locked property to graphically edit the object.
