It is possible to scale objects, that is, bonds, reactions arrows, graphical objects, or text boxes can be scaled. Both individual objects and sets of objects can be selected,

To scale an object, follow the steps below.

  1. Select the desired object.

  2. Drag one of the corners of the bounding rectangle and drag it.

  3. The selection is scaled proportionally.


In the case of bond scaling, the percentage of the current bond length relative to the default value will be visible.

The same result can be achieved by opening the Format dialog either through the Edit > Format option or from the context menu.
