 this is the abstract work i choose for final delivery.

course started with the action of boolean command. it helps to understand substraction , adition or intersection better. first action was creating box with the help of command box ( 10,10,10) . then making another box with the copy action. then making cone with the command cone with the size of 5-5 . then copying again to the 0.5 unit far to have subtraction. then with shade, it is given 3d look.

 I started doing this assignment with  tetraerdo aka 4 faces polygon. surface is made by triangle and polygon consist of 4 utterly same dimensions. it was done by pyramid command, and press 3 for edge . secondly hexaedro  aka 6 faces polygon is made. it c onsists of 6 faces of square. it is also cube. made my command cube  octahedro is made by combining pyramids.with the commands pyramid and 3drotate it was combined to have final look  didacro  has 12 faces of 5 face polygon.it is done by first polygon command and drawing circle around. and with command mirror second 5 faced was added. and with ucs coordination change 2 circles were done. intersection point that these circles have is the point for first move. after doing that action, with command arrayclassic, it was completed. icosahedron has 20 faces based on triangles.it was made first with command polygon with 5 faces, then having triangles due to sides that 5 face has. then with ucs command c

firstly, three different way of making cube on autocad were shown. first drawing was done with command box 10,10,10 dimension .  and then with shade command  depth and shade were given . secondly, other cube was given with extrude command . 10 units were used as measurement. thirdly , third cube was done by its open state. it was closed with 3drotate or rotate3d commands.

In this class two axises were created by line command. These axises were made by middle point and nearest point command. Then d-v points were created to make unit circle , therefore refereance points were observed clearly.   Then 5 radius circle were created, with offset command 6 more lines were made for making paraboll. Then,new layer created as ‘’ paraboll’’ . curve and spline commands were created to continue for making paraboll. The paraboll we created has 0.5 thickness. With pedit command half circles and thickness   were joined together. Finally, density were converted from 6 to 30 by using surftab1 and surftab2 command. For a final move, it gained thickness and 3 dimension. commands used :  command:  line  ,  xline  ,  offset  ,  move  ,  scale  ,  dtext  ,  osnap  ,  ortho  ,  nearest  ,  trim  ,  mirror
