SDC PUBLICATIONS © 2011 Chapter 3 Geometric Construction and Editing Tools Learning Objectives:  Set up the display of Drawing Units.  Display AutoCAD's toolbars.  Set up and use OBJECT SNAPS.  Edit, using EXTEND and TRIM.  Use the FILLET command.  Create parallel geometric entities.  Using the PEDIT command.  Use the EXPLODE command.

SDC PUBLICATIONS © 2011 AutoCAD® 2012 Tutorial First Level: 2D Fundamentals Geometric constructions The creation of designs usually involves the manipulations of geometric shapes. In technical drawings, many of the geometric shapes are constructed with specific geometric properties, such as perpendicularity, parallelism and tangency. For example, in the below drawing, quite a few implied geometric properties are present.
