    Create a graphical object
    1. Select the desired graphical objects from the Tools tool bar or the Insert menu.

    2. Click and hold the left button, move the mouse and release the button.

    3. To create the object click again.

    Select a graphical object

    Similarly to the structure selection graphical objects can be selected using all selection buttons and shortkey.

    Resize/reshape a graphical object

    Hovering a graphical object its control points become active and highlighted by blue. Dragging an active control point the object can be reshaped.

    Change the style

    To change the style (thickness, color) without affecting defaults, right-click on the selected object or objects (they can be of different type) and choose Format... option which opens the Graphic Object Properties dialog.


    These changes are identical with those applied to structure. For more information see the Geometric transformation of structure and objects section.

    Delete a graphical object

    Graphical object can be removed in same ways as structures. These ways are covered in Deleting a Structure section.


    Lines look similar to simple single bonds but behave differently:

    • they do not carry chemical meaning

    • crossing lines appear solid, but bonds do not

    Lines are defined by their two endpoints. There is also a third one at the midpoint. This control point can be used for change the line into a curve (for controlling the arc angle) or it can be used as joining point to other objects.

    If this control point is used to connect two objects, it can be relocated while the other endpoint of the line remains fixed.


    Curves can be draw by changing a line or a curved arrow.

    1. Select the midepoint.

    2. Drag the control point to change the curvature. Alternatively, in the Graphical Object Properties dialog box Arc central angle can be set manually.

    3. Remove the mouse pointer to unselect the curve.

    Rectangle/Square - Rounded rectangle/Rounded square

    The shape of an object is changeable or resizable by dragging one of its points.


    To draw a polyline

    1. Select the Polyline toolimages/download/attachments/5317910/g-polyline16.png from the Tools toolbar active.

    2. Use dragging in combination with clicking to draw.

    3. Press Esc or choose an other icon from the toolbar.
