Que.1.

Aim :- To draw the above figure in AutoCAD

Introduction :- Decimal units are unitless — that is, they’re not based on any particular real-world unit. With decimal units, each unit in the drawing could represent an inch, a millimeter, a parsec, a furlong, a fathom, a cubit (if you’re into building arks in case that rainy day should come), or any other unit of measure you deem suitable, from Danish alens to the Swiss zoll. An example would be 15.5.

Aim :- To draw the above figure in AutoCAD

Introduction :- Architectural units are based in feet and inches and use fractions to represent partial inches: for example, 12′3 1/2″. The base unit is the inch unless otherwise specified, so if you enter a number like 147.5, then AutoCAD will understand it to be 12′3 1/2″.
