Challenge

Understanding and implementing shell feature sketch blocks and Linear pattern in Solidworks

Aim: To model oil tank, chain and pedal of an American chopper using Solidworks.

Commands used: Following were the commands used to model the parts,

Oil Tank

Main features: Combine feature and shell.

A 2D Sketch is created as per the given the dimension in the top plane.
The sketch is then extruded on both directions 170mm in one direction and 10mm in other.
A new sketch is created on the midplane( front) and extruded into both the directions using through all option.
Combine feature is used to build a common part using both the models.
Fillets are applied at the edges and shell feature is applied with thickness 3mm and previewed using cut section to ensure that shell is applied.
Appearance of the oil tank is changed to sienna with white at the edges.
Part is saved.

Chain

Main features: Curve driven pattern and mirror.

After renaming the planes sketch is created at the midplane according to given dimensions.
A runaway sketch is created at the midplane and blocks are creates, namely as chain_link1 and chain_link2, in order to save them as a separate part and use them to create the links.
The blocks are inserted on to the 2D sketch created on the midplane and applied certain relations to make coincident with the curve .
The blocks are then extruded and fillets are applied at the faces of the pin.
Curve driven pattern is applied along the curve and some extrudes are drawn manually to perfectly align with the chainpath.
Later the solid bodies are classified into chain plates and pins in separate folders to keep them more organized and the chain plates are mirrored using mirror entity.
Chrome Appearance is applied to the chain.
Part is saved.

PEDAL

Main features: Linear pattern, revolve, chamfer and dome.

2D sketch is created at the front plane as per given dimensions and extruded using etruded boss/base upto 8mm.
A new sketch is created on the front face of the model and extruded upto 20mm.
Another sketch is created on the other face of the model and is revolved using revolved boss/base feature.
Dome feature is applied at the end face of the revolved part.
Unsymmetrical chamfer is applied to other two parts.
A new sketch is created by using offset entities option at the base of the three parts and is extruded from the face at an offset of 20mm of 2.5mm.
Fillets are applied to the newly created extruded parts and linear pattern is applied to create four instances of the same at a spacing of 20mm.
Fillets are applied to the remaining edges of the model.
Part is saved.
