Challenge 6 : Concept Modeling of Side Fender
Title Of The Project: Concept Modelling of Side Fender
Objective: To build the surface for the side fender.
Introduction:
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch and is the portion with wich other materials first interact. Surface provides a geometrical description of the article boundary with none topoogies data.
Autodesk Alias (formerly known as Alias StudioTools) is a family of computer-aided industrial design (CAID) software predominantly used in automotive design and industrial design for generating class A surfaces using Bezier surface and non-uniform rational B-spline (NURBS) modeling method.
Design Approaches:
Descriptoin:
1. Import the given image as canvas in one of the layouts as shown:
Since, only one view of the fender is given, we have to build the surfaces by visualizing the surfaces on our own.
2. After importing these images, make layers and assign these images to a particular layer and make it as reference. Also, make layers as required.
3. Now, by creating a particular section of the fender, we can build the other regions with the reference of this region. By visualizing the surfaces of the fender, we will be able to build the curve networks as shown in the figure below:
4. By using these curve networks, we can build the surfaces as shown in the figure.
5. Trim the unwanted regions by using the trim command in the surface edit option as shown in the figure:
6. Fillet the sharp edges of the fender by using the surface fillet command.
Features Used:
To build the curve netwoks, cv crv and blend commands are used.
Surfaces are generated using Surface Tools surch as:
- skin: Creates a skin across multiple curves
- rail: Extrude profile freely or on path curves to make sweeping
- square: fill in the boundaries outline by connecting curves
After creating these surfaces, they are aligned and the continuity is applited to the adjacent surfaces. The surfaces are aligned using the Align tool and the continuity is checked using srfcon under evaluate tab.
In order to create some cut-outs on the surfaces as shown in the figure, first of all the curves are projected onto the surface and the unwanted surface is trimmed out using project tool and trim tool respectively.
In order to know the construction history, you can use the following tool:
To form Fillets between the surfaces, 'Surface Fillet Tool' is used.
Conclusion:
Hence, the surfaces of the fender is built.
Different views of the fender:
1. Left View
2. Front View
3. Back View
4. Isometric/Perspective View
