Creation of geometries by Coordinate system methods using AutoCad
Create the geometries from P1 to P2 using all the coordinates system methods. You need to use the Line tool to create the geometries. Where required you need to use the circle tool.
Please read the drawings and find out the missing dimensions before working on the sketches.
Note: Use the Imperial Template and the Decimal Units to draft the features. Dimensions are there forreferences.
AIM: TO CREATE THE GEOMETRIES FOR THE GIVEN FIGURES USING THE DIFFERENT TYPES OF COORDINATE SYSTEM METHODS.
First set up the Drafting settings for Grid as 1 for X and Y axis each and the major lines every 10 divisions.
