A keepout object has the same geometric structure as a shape object and can therefore consist of a sequence of linked line, arc or curve segments. When a keepout object is selected and the Edit tool is active, the control hooks of its individual segments are displayed.

When the control hooks are visible, the following operations can be performed:

  • Drag the hooks located in the vertices of the linear segments.

  • Drag the hooks on the ends of the arcs to adjust the opening of the arc.

  • Drag the hook placed in the center of an arc to move the arc.

  • Drag the control hooks of a Bezier curve.

  • Drag the control hooks of a spline curve.

  • Click anywhere on the object and drag the mouse to move the object.

  • Right-click on a hook to display the corresponding menu of commands.

Consecutive Bezier Curves

When two Bezier curves are consecutive, the common point between the two curves can be set to one of the following modes:

Commands in the hook menu

Command Description

Move All

Moves all active hooks. Displays the Move dialog box.

Deselect All

Deactivates all active hooks.

Select Hook

Activates the clicked hook.

Deselect Hook

Disables the clicked hook.

Move Vertex

Displays the dialog box in which to specify the new vertex coordinates.

Insert Vertex

Adds a new linear segment by inserting a vertex at the midpoint of the segment.

Remove Segment

Removes the segment to which the hook belongs.

Convert to Line

Converts the segment to a line.

Convert to Arc

Converts the segment to an arc.

Convert to Bezier

Converts the segment to a Bezier curve.

Convert to Spline

Converts the segment to a spline curve.

Toggle Direction

Reverses the direction of the arc.

Set Center

Set the center of the arc.

Set Axes

Sets the length of the axes of an ellipse arc.

Start Angle

Displays the dialog box in which to specify the new value of the starting angle.

End Angle

Displays the dialog box in which to specify the new value of the end angle.

Move Point

Displays the dialog box in which to specify the new coordinates of the point of a spline curve.

Insert Point

Adds a new point in a spline curve.

Remove Point

Removes a point from a spline curve.

Angular

Sets the point of a Bezier curve as the angular point.

Smooth

Sets the point of a Bezier curve as a slight damping point.

Symmetrical

Sets the point of a Bezier curve as a symmetrical point.

Move Cutout

Displays the Move dialog box.

Rotate Cutout

Displays the Rotate dialog box.

Properties Cutout

Displays the Properties dialog box.

Show reference point

Displays the transformation center of the selection. The transformation center is initially hidden and is set in the center of the selection rectangle. See the Transformation center.
