Challenge 8 : Concept Modeling of Seats

1. Title of the Project:

Development of Car Seat using Alias Auto Studio

2. Objective

To build the seat of the car using the Curves traced from the given blueprint of the model.

3. Introduction

Surface modelling is the art of building complex geometrical features, one surface at a time. Usually surface modelling is used to create flowing, organic shapes, so the patch meeting between surfaces are more important.

We describe the 'smoothness' of a junction, where one surface meets another, the term ‘G’ stands for “Geometry”. The more alike the surfaces flow must be more smoothly the adjoining surfaces.

4. Design methodology / approach :

A design approach for modelling this car seat has been briefly explained below using flow chart.

5. Description of Modelling:

Concept modelling is done by various methodology, here we have blue print of the Car Seat. It’s easier to develop the model by tracing out the curves of the seat by curve generate options. Once the curve networking is done, we pour the surfaces to curve which gives volume to your model.

In the working layout we are going to import the canvas image proportionally as shown below in the figure.

Once the canvas images arranged according to the view, curve tracing has been initiated by using the key point curve tool with maximum 5 degree curve. This curves are arranged according to the shape of given blue print by the stretching CV hulls in all proportion view to build as 3D object.

The upper part of patch is constructed by align the curve to flow by G2 curvature continuity to get the surface flow over the edge curve as shown below.

At the meeting point of two edges are so complex to make smooth surface it is trimmed and align according the required shape. It is filled by using the Free form blend to achieve the closed surface area.

Once half of the part of steering wheel is completed it is duplicated to required axis to get full completed steering wheel, by using symmetric option.

7. Conclusion

Modelling of car seat has been developed successfully by using Curve networking and Surface volume. It has been built by using the Blue print of the car seat, it is shaped according to the proportion in perspective manner. Modelling strategy of the car seat has been discussed briefly with feature used to make surface volume in the pictorial representation.
