Objectives
- The objective of this project is to create a model of different parts of Chopper using
- Create an assembly of the different parts modeled for the chopper.
- Create a Photorealistic model of the chopper and render the model using SolidWorks Photo view 360.
Introduction
SolidWorks part model is a collection of geometrically and dimensionally related features that represents a physical object. A part file contains a single part. In SolidWorks, parts are combined to form assemblies. In an assembly, parts can be created in relation to the geometry and topology of parts already in place.
To model a part in SolidWorks, you start by drawing sketches to define feature profiles and paths. You can then use commands to apply parametric geometry to the sketched geometry and generate three-dimensional part features. Finally, you combine the features to create parts.
Although, you create most features from sketched shapes, or profiles, some features, such as chamfers, fillets, and shells, are well-defined mechanical operations that do not require sketches. Sketched features can join, cut, or intersect with another feature.
You combine features to create complex parts. Features are positioned using geometric constraints and dimensions. If you leave some curves on features undimensioned, you can make the feature adaptive, which means it can change size when you constrain it to fixed geometry in an assembly.
Terminology
- 3D Design
SOLIDWORKS uses a 3D design approach. As you design a part, from the initial sketch to the final result, you create a 3D model. From this model, you can create 2D drawings or mate components consisting of parts or subassemblies to create 3D assemblies. You can also create 2D drawings of 3D assemblies.
- Origin
Appears as two blue arrows and represents the (0,0,0) coordinate of the model. When a sketch is active, a sketch origin appears in red and represents the (0,0,0) coordinate of the sketch. You can add dimensions and relations to a model origin, but not to a sketch origin.
- Plane
Flat construction geometry. You can use planes for adding a 2D sketch, section view of a model, or a neutral plane in a draft feature, for example.
- Sketch
Create the sketches and decide how to dimension and where to apply relations.
- Features
Select the appropriate features, such as extrudes and fillets, determine the best features to apply, and decide in what order to apply those features.
- Convert Entities
The Convert Entities tool lets you create a sketch by projecting a set of edges onto the sketch plane. In this example, the left and upper edges are projected.
- Chamfer
A cut on the edge or corner of something that makes it sloe slightly rather than being perfectly square.
- Liner Pattern
Liner pattern is also more like a circular pattern. The feature is pattered linearly. Pattern is a kind of tool like array available in AutoCAD.

Assembly of Chopper
- Initially, the Chassis part is inserted in the assembly by using insert parts in the option. After then the part is inserted in the assembly environment and clicked ok to fix the chassis.
- After that the other parts of the chopper are inserted into the assembly and the given possible mate conditions are applied.
Photo Realistic Rendering
- Rendering is the process of creating realistic image of the photorealistic model with the environment.
- In the photorealistic model some of the mate conditions and positions are changed to render realistically.
- Then the photorealistic model is rendered into realistic images with he different views.
Conclusion
- The parts of the chopper are modeled using most of the Solid modelling Tools in
- The parts are inserted into the assembly environment and the chopper is assembled. Getting used to with Assembly Module of SolidWorks.
- The realistic image was rendered with the use of Photoview 360 & SolidWorks visualize.
