The Bezier dialog.


This dialog allows the designer to specify the properties of an Bezier object. A Bezier curve is a non-electrical drawing primitive. It is a free-form curved line that can be placed on a schematic sheet. The curve is defined by a series of vertex points that 'pull' the line into a curved shape.

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


The Bezier 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 bezier object to be changed, which will be applied when placing subsequent beziers.

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

While attributes can be modified during placement, bear in mind that these will become the default settings for further placement unless the Permanent option on the Schematic – Default Primitives page of the Preferences dialog is enabled. When this option is enabled, changes made will affect only the object being placed and subsequent objects placed during the same placement session.

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

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


  • Curve Width - the line width used to draw the curve. Available widths are: Smallest, Small, Medium, and Large.
  • Color - click the color sample to change the color of the curve, using the standard Choose Color dialog.
  • Locked - enable this option to protect the curve from being edited graphically.
If attempting to graphically modify an object that has its Locked property enabled, a dialog will appear asking for confirmation to proceed with the edit. If the Protect Locked Objects option is enabled on the Schematic – Graphical Editing page of the Preferences dialog, and the Locked option for that design object is enabled as well, then that object cannot be selected or graphically edited. Double click on the locked object directly and disable the Locked property, or disable the Protect Locked Objects option, to graphically edit the object.
