Q 1

AIM:- To create a 3D Furniture element as shown in the Figure. I have assumed dimensions which are missing.

INTRODUCTION:-

To draw this warframe of a 3D Furniture element as shown in the Figure, I have used several coordinate systems like- rectangular coordinate system, spherical coordinate system. Apart from that, I have used several commands like- Line, Rectangle, 3Dorbit, Extrude, Region, UCS etc., and I set dimension (Engineering) and select inches in Autocad. Moreover, I set limits with command "Limits", specify the left corner points ans right corner points and then enter zoom all("z-a") in this drawing. Also, I used dimesion command for measuing the dimensions in Autocad along with text command to write drawing name. Apart from that, I have assumed several data for drawing this sketch.

PROCEDURE:-

Open Autocad and type a command "Unit" and press enter, then set unit as Engineering and set angle in degree- base angle is east -mark angle direction as anticlockwise. Type a command "DIMSTYLE" and press enter, then click to modify and go to primary unit tab and set it Engineering and set the precision to 0'-0" and cick ok.
