A shape is a sequence of line, arc or curve segments linked together and forming a single object. When a shape object is selected and the Edit tool is active, the control hooks of the individual segments that make up the shape are displayed.

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

Drag the hooks (1) located in the vertices of the linear segments.
Drag the hooks (2) on the ends of the arcs to adjust the opening of the arc.
Drag the hook (3) placed in the center of an arc to move the arc.
Drag the hooks (4,5,6,7) on the ends of a Bezier curve.
Drag the control hooks (8) of a Bezier curve.
Drag the hooks (10) on the ends of a spline curve.
Drag the control hooks (9) of a spline curve.
Click anywhere on the shape 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:

Angular point. The angular points have two control hooks that can be moved independently; the curve course through the angle will not continue smoothly but will form an angle.
Slight damping point. The two angle control hooks are oriented in parallel and can only be moved simultaneously. The lines of the control hooks can be of different lengths, allowing the degree of curvature to be varied.
Symmetrical point. The two angle control hooks are aligned in parallel and have the same length. They can only be moved simultaneously and with an equal degree of curvature in both directions.

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.
Closed figure	This option automatically closes a figure by adding a line segment between the initial and final ends of the figure.
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.
Change Figure	If the shape is made up of several figures, the active figure changes. Present if the shape includes holes.
Move Hole	Allows you to change the position of a hole within the shape. Displays the dialog box where you can specify the width of the horizontal and vertical shift. Present if the shape includes holes.
Rotate Hole	Allows you to rotate a hole inside the shape. Displays the dialog box in which to specify the rotation angle. Present if the shape includes holes.
Resize Hole	Resize a hole inside the shape. Displays the dialog box in which to specify the scale factor. Present if the shape includes holes.
Delete Hole	Removes a hole from the shape. Present if the shape includes holes.
Move Shape	Displays the Move dialog box. This command acts only on the object to which the clicked hook belongs and allows you to move an object included in a group independently of the other objects in the group.
Rotate Shape	Displays the Rotate dialog box. This command acts only on the object to which the clicked hook belongs and allows you to rotate an object included in a group independently of the other objects in the group.
Resize Shape	Displays the Resize dialog box. This command acts only on the object to which the clicked hook belongs and allows you to resize an object included in a group independently of the other objects in the group.
Properties Shape	Displays the Properties dialog box. This command acts only on the object to which the clicked hook belongs and allows you to modify the parameters of an object included in a group independently of the other objects in the group.
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.
