Sketch This tool is used to create a new sketch or edit an existing sketch. The optional tool is Exit Sketch shown below.

Exit Sketch 

This tool is one method that is used to exit and save the current sketch. Applying this tool will exit the Sketch Environment back to the Part Environment.

 Smart Dimension 

Smart Dimensions also referred to as Dimensional Constraints (numerical values such as length, distance and angle, radius and diameter). The optional tools (not shown) are Horizontal, Vertical and Ordinate dimensions.

Line This tool is used to create all lines (single and/or multiple lines). The optional tool is Center Line and shown below.

Trim Entities

This tool is used to trim sketch entities.

Display/ Delete Relations

This tool is used to display the sketch relations (Geometrical Constraints).

Fully Define Sketch
