You can access all the Sketcher tools through either the main menu bar or the toolbox. Figure 191 shows the hidden icons for all the tools in the Sketcher toolbox.
To see a tooltip containing a brief definition of a Sketcher tool, hold the mouse over the tool for a moment. For information on using toolboxes and selecting hidden icons, see Using toolboxes that contain hidden icons, Section 3.3.2.The Sketcher tools allow you to do the following:
Create basic sketch entities, such as lines, circles, arcs, ellipses, fillets, and splines.
Add construction geometry to your sketch to help you position and align sketch entities.
Add dimensions to your sketch to make your sketch geometry more precise.
Modify your sketch by moving vertices or changing dimensions.
Create similar objects by copying, offsetting, or creating linear or radial patterns of objects.
