Features I have learnt while designing Chasis-

• How to insert sketch by using sketch tool and give them the proper dimension & Relation.
• Combine feature
• Split tool

1 First select the part template from the ultimate solidworks template.

2 Now we will change or rename Front plane, Top plane as midplane chasis, bottom plane chassis correspondingly.

3 Now by using sketch tool we will insert sketch on midplane chasis, give it proper positioning on plane.

4 Now rename the sketch as “blueprint chopper”.

5 Now on midplane chasis make concentric circles. The distance between two circles will be 4 mm and also give them the proper dimension and relation from the origin.

06 Again on midplane chasis we will make the required sketch by using line tool and spline tool.

07 Now on right plane we will make the the required sketch by using spline tool and give it the required dimensions and relation.

08 Now we will use both sketches to create a projected curve.

09 Now we will use sweep feature to sweep that circle along that projected curve to create the base of chasis.

10 Now we will use the mirror feature to mirror the required part about the midplane chasis.

11 Now make the below given sketch by using circle, line and construction line tool with appropriate dimension and relation.

12 Now we will create extrude cut through above extruded surface by using offset tool, cut extrude feature and fillet tool.

13 Now apply chamfer and fillet wherever needed

14 Now create a plane at appropriate place along midplane chasis.

15 Now on that plane make the below given sketch.

16 Now by using circle tool we have made on frame sweep it along that curve.

17 Now repeat the above two steps but with different position.

18 Now on that same plane we have created, make a circle of 95 mm at appropriate position and extrude by extrude boss / based feature.

19 Now on the above extruded part, sketch a circle of 60 mm and extrude it by 223 mm to make Axle.

20 Now make the below given sketch on midplane Chasis.

21 Now create an appropriate plane along right plane and make concentric circles of 32 and 40 mm.

22 Now by using sweep feature project the circles along the curve we have made earlier.

23 Now use split feature to cut the unwanted part.

24 Now on midplane chasis make the below given sketch.

25 Now create a plane at the end point of spline.

26 Now on that plane make cocentric circle and then extrude it by using sweep feature along the spline curve.

27 Now use sweep option to remove unwanted part from the internal space of tube.

28 Now we will use combined feature to combine all the individual entities of chasis.

29 Now on midplane chasis make the below given sketch.

30 Now use Revolve Boss/based feature to extrude above sketch about appropriate axis.

31 Now use split feature to cut unwanted extruded part.

32 Now for horizontal plates joining tubes of chasis we will create required sketch using line tool with appropriate dimensions.

33 Now use extrude Boss/base feature to extrude it by using midplane feature upto tube of chasis.

34 Apply fillet wherever needed.

35 On midplane chasis make below given sketch with appropriate dimension and relation and extrude it by appropriate value.

36 Now use split feature to remove unwanted part.

37 Now use mirror feature and mirror the above extruded part for pedal holder.

38 Now use combine feature to combine it with chasis

39 Now apply fillet wherever needed.

40 Now make below given sketch with appropriate dimension and relation and extrude it by using Boss/ base feature about 40 mm.

41 Now apply fillet wherever needed

42 Now on kickstand holder create a circle of 12 mm at appropriate position and by using extrude cut create a hollow space in kickstand holder.

43 Now create a new plane above bottom plane chasis and name it bottom plane fuel tank.

44 Now apply Sienna appearance or material to the whole chasis.

45 Now save the part as “chasis”.
