Sketch objects have options which you can change. These options allow you to customize your sketch. Two different methods are used to change sketch options:
Click with the right mouse button on a sketch object (for the Macintosh, Ctrl + Click)
Select the sketch object (variable, arrow, etc.) then use the Status Bar to change the options or attributes of the selected object.
Selecting Sketch Objects
Several methods allow you to select single or multiple sketch objects.
•Click on a single object with the Move/Size tool.
•Select multiple objects by holding the mouse button down and then dragging the Move/Size (or Lock) tool over a region of sketch.
•Select multiple objects by holding down the Shift key and clicking on each object with the Move/Size tool.
•Select the whole sketch with Edit>Select all (or Ctrl + A).
•Deselect objects which are selected by holding down the Shift key and clicking on each object with the Move/Size tool.
•Deselect all objects by clicking on a blank region of sketch (outside of the selection rectangle).
