Drafting of various geometries using Chamfer, Fillet tool in AutoCad

AIM To Draw the given geometric diagram in AutoCAD with different units of measurement

Introduction 

Types of units measurement in AutoCAD:-

AutoCAD is extreamely flexible about drawing units, let us have them in our way AutoCAD's Length unit types are as Follows 

• DECIMAL UNITS:The decimal units can be represented as an inch, meter, millimeter, or any other unit.
• ENGINEERING UNNITS:The engineering units are like architectural units, but they represent the feet and inches in the format of the decimal. For example, 4'5.5000".
• ARCHITECTURE UNITS: The architectural units are based on the feet and inches. It uses fractions to represents the partial inches. It displays feet and inches in the format of decimals and fractions. For example, 4'- 5 1/2".
  Here, single quotes (') signifies feet and double quotes (") signifies inches.
• FRACTIONAL UNITS : The fractional units are the unitless decimal units, which display the value in fractions rather than decimals. For example, 5/2.
  It also represents whole numbers or whole numbers with fractions. For example, 5 ½.
• SCIENTIFIC UNITS : The scientific units are used to display the units in the form of the decimal value raised to a power. It displays the value of exponents. For example, 2.600E + 04. It is used to display large values.
