16. In new GS, create a plane 2.5mm away from the origin and parallel to xy plane. draw a enlongated hole profile of total length 150mm at desired location. extrude the current profile to 20mm and mirror it with respect to xy plane in new body. remove the current body from the main part body using remove command to the desired result.
17. In new GS, draw a profile on xy plane using line and circle concentric to origin. extrude it to 14mm on both side along z-axis in new body, then remove the current body from the main part.
18. In new GS, draw a circle of D63mm concentric to origin point on xy plane and extrude it to 35mm on both side along z-axis in new body. add the current body to the main part body using add command.
19. In new GS, draw a circle of D35mm at 250mm away from origin on the xy plane and extrude it to 21mm on both side in new body. add the current body to the main part body.
20. In new GS, draw a circle of D52mm with its centre coincident to origin on xy plane and extrude it to 35mm on both side along z-axis in new body. remove the current body from the main part body to create bearing hole.
21. In new GS, draw a circle of D24mm on xy plane at 250mm away from origin and extrude it to 21mm on both side along z-axis in new body. remove the currnt body from the main part body to create hole for rod bush upper.
22. In new GS, draw 4 circle of D10mm on xy plane at required location and extrude it to 35mm on both side in new part body. remove the current body from the main part to create hole for link pin.
23. Under product, create a new part body and name it as Articulated rod. in xy plane draw a profile using 2 circlr of D35mm & D24mm and a centre rectangle. dist b/w circles to be 178mm and rectangle breadth 18mm. centre of circles & rectangle should be coincident with the y-axis. extrude the profile to 9mm on both side along z-axis.
24. In new GS, draw a elongated hole of R5mm with total length of 130mm on plane parallel to xy plane at 2.5mm away from the origin. extrude the profile to 6.5mm on both side along z-axis and mirror the part to other side using xy plane as reference in new body. remove the current body from the main part.
25. In new GS, draw a circle of D35mm at required location on xy plane and extrude it to 21mm on both side along z-axis in new body and add the current body to the main part.
26. In new GS, draw a circle of D24mm on xy plane and exturde it to 14mm on both side along z-axis in new body and add the current body to the main part.

Drafting

1. Open drafting work bench and select the ISO standard with sheet size of A0.
2. Select the isometric view command, then go to product work bench and click on any surface of the assembly inisometric view to create a drawing of assembly under isometric view in drawing sheet.
3. Select the isometric view command, then go to product work bench and click on views under application. then click on any surface of the assembly to generate a drawing of exploded view of the assembly in the drawing sheet.
4. Select the exploded view drawing and select balloon generation command to create balloon numdering of the assembly.
5. Select Bill of Material command to create a BOM of the parts assembled in the assembly of the product.
