Construction Steps:

• Create new part
• insert the 2D sketch picture (Position -930.00mm,-805.00mm,0.00deg,3508.00mm,2480.00mm)
• Rename it as Blueprint Chopper.
• Draw 2D for Enginecase
• Go to Features>curves>projected curve>select both curve>ok
• Create another projected curve
• Feature>Swept Boss/Base>select curve which is created>ok
• Mirror it across the midplane chassis select the feature which we have created.
• Draw the 2D fully defined sketch accordingly
• Feature>extrude>22mm reverse
• Feature>extrude cut>upto next>ok
• Next apply Chamfer of distance distance 90mm and 44mm
• Apply 25mm fillet to the outside edges
• create the reference plane from the midplane chassis to the vertex.
• Go to feature>swept Boss/Base>select the path>click ok
• Feature>Extrude>223mm>ok
• Apply Dome of 10mm
• Create new reference plane to the end of the spline
• Go to feature>Swept Boss>Select the path click ok
• Then Split the remaining body
• Again create reference plane to the end of the spline.
• Go to feature>Swept Boss>Select the path>ok
• Again use split tool to cut the bodies.
• Go to feature>revolved boss>select the construction line>ok
• Again use split tool to cut the remaining bodies
• Go to Feature >Boss Extrude>select direction 1&2>up to next >ok
• Apply 2mm fillet
• Feature>Extrude>offset 165mm>for direction 1>midplane extrude of 10mm>ok
• Again use split feature to cut the bodies
• Apply fillet of 20mm and 1mm radius
• Mirror it across the midplane
• combine all three
• Apply 3mm fillet
• insert reference plane up 308mm
• Change the apperance to painted car sienna

2. Engine

Construction Commands:

• Draw a 2d sketch
• Extrude
• Extrude cut
• thin Extrude
• Chamfer
• Projected curve
• Linear pattern
• Circular pattern
• fillet
• Mirror
• Dome
• Sweep

Steps Involved:

• Create new part
• Insert the sketch picture
• Draw the sketch
• Go to Feature>Extrude Boss>Midplane extrude of mm
• Feature>select circle>from surface>50mm
• Feature>extrude 80mm circle>surface>blind 40mm extrude
• Go to Feature>Boss Extrude>midplane>150mm
• Apply fillet of 50mm
• Draw the 2D sketch
• Go to Feature>revolve>ok
• Turn on temporary axis
• Again make the revolve about the temporary axis which we have created.
• Draw a 2d Sketch
• Make the circular pattern of 40 instances on the circular edge front pulley
• make the circular pattern of 44 instances on the rear pulley
• make the circular pattern of 12 instances on the front pulley
• Go the Feature>cut Extrude>offset of 250mm>offset from surface>select dome face>offset it 3mm
• Repeat it for another pulley
• Apply chamfer of 3mm and 45deg
• Apply 1mm fillet to the all open edges
• Draw the 2d sketch
• Go to Feature>Boss extrude>midplane extrude of 150mm>ok
• Again go the Feature>Boss Extrude>Select Small Area>Midplane extrude of 110mm>Ok
• Draw 2d sketch on the Ref plane which we have Created
• Go to feature>Extrude>upto vertex>ok
• Feature>Boss extrude>Blind of 125mm>ok
• Now apply the chamfer of 90mm and 15mm
• Apply the fillet of 15mm the all edges
• Draw the 2d sketch
• Go to feature>extrude cut>offset of 26mm>Direction1 8mm>ok
• Do the linear pattern spacing of 16mm and no of instances of 14
• Apply 2mm fillet to all internal and external edges
• Apply 10mm fillet
• Apply 5mm fillet
• Extrude>2mm>ok
• Apply dome of 2.5mm
• Go to feature>Extrude>midplane>20mm
• Apply 10mm fillet
• use split tool and cut the bodies
• Go to Mirror>select Body>Across right plane>ok
• Apply 25mm fillet
• Apply fillet of 5mm
• Feature>Extrude>15mm
• Go to feature>select bodies>upto next>ok
• Apply fillet of 2.2mm
• And do the circular pattern of 21 instances on the face
• Apply chamfer of 24mm and 75mm to the base edge.
• Apply chamfer of 5mm and 45deg
• create swept boss
• Go to Feature>Swept Boss>Slect 45mm circle
• Do the revolved boss across the construction line
• Apply 5mm fillet
• Go to Feature>Extrude cut>offset from surface>2mm
• Draw a 2d sketch
• Go to feature>curves>projected curve>select 2 sketches>ok
• make another projected curve
• make both curves as composite curve
