Photo Realistic Rendering

1. REPORT ON ASSEMBLY OF CHOPPER MODEL

DESIGN OF AMERICAN CHOPPER USING SOLIDWORKS

OBJECTIVE

The objective of the project is to modelon AMERICAN CHOPPER using a CAD (computer aided drafting} soltwore­

SOL/DWORKS and to render it with SOL/OWORKSvisuolize to create a photoreolistic view of it.

INTRODUCTION

This project explains the designing of American chopper using the CAD software SOLIDWORKS from sketching the ports and modelling them to final rendering of the assembly to give a photo realistic view.

METHODOLOGY

• Port Modelling
• Assemb ly
• Rendering

PART MODELLING

In part modelling ,first the 20 sketch of the part is sketched using the tools in sketch tab and then the 2Dsketch is converted into a 30 part using features in the features tab.

FEATURES USED

Boss Extrude: This feature is used to expand the object in 30 according to sketch plane.

Extrude cut Extrude cut feature used to cut/remove the 3d object in linear path according to sketch.

Fillet: Fillet is a feature used for making round internal or external edges to avoid sharp edges and make it smooth.

Lofted Boss/Base: Lofted boss is a feature used to achieve Complex Shapes. It does this by interpolating surfaces between various cross-sections of a model .These cross-sections can be sketches ,faces ,or edges.

Split /: Split tool is used to split single solid part into two sold parts. It is used to project an entity onto other surfaces or curved/ planar faces.

Dome. Dome is a feature used to make dome shaped extrude including elliptical dome.

Shelf. Shell feature is used to make to hollow space in solid part by selecting outer wall of the solid part and so removes the inner parts .It is also used to reduce the specific thickness.

Combine. Combine tool is used to make integration of two sold parts which intersect each other as same solid part.

Chamfer. Chamfer is used to make a sharp edge or corner slightly tapered rather than being a perfect square.

Linear Pattern: The linear parent is used to create a different number of instances required to create the pattern linearly.

curve Driven Pattern. Curve driven pattern is used to make any pattern which followed by the curve is sketched before.

Circularpattern : Circular pattern is a feature used to make 3d feature into circular pattern according to number of insistences.

Revolve boss base: Revolve feature is used to make cylindrical or circular 30 extrude along with a given reference axis as per drawn sketch.

Revolve cut Revolve cut is used to cut or reduce the extrude of cylindrical round surface. Move/copy body This feature is used to move/copy the 30 body to one place to another place. Mirror. Mirror is used to mirror a feature or body by reference of the selected plane.

Sweep This feature is used to sweep any kind of fully defined sketch along with the path.

Sweep cut. Sweep cut is same as sweep feature but its directly proportional ta sweep which makes a cut along with the sweep path.

Swept Surface-. It is used to make a surface along with a path the curve is driven.

Boundary Surface-. Boundary surface is used ta make a surface in between two f finished surfaces.

Loft Surface-. Loft surface is used to make loft in between two profiles along with guide path.

Knit surface'. Knit surface is used to knit the two free edges or open edges of the surfaces together also it reduces the gap between the two edges of the surface.

Surface Trim: Primarily used to cut away material fr om a surface ,and provides two modes :Standard and Mutual.

Projection curve: Projection curve is a 30 curve which is projected on the basis of the two different 20 curves in two different planes.

Blocks-. You can make save, edit and insert blocks from the drawing items and sketch entities that you use often such as standard notes ,title blacks, label positions and so an you can attach blacks to geometry or to drawing views

Trimentities : it is used to trim the unwanted lines or extended entities in the sketch.

Appearances :An appearance def ines visual properties of the model including colour and texture. Appearances do

not affect physical properties which are defined by materials . every material is a assigned a default appearance.

ASSEMBLY

Assemb ly is most often referred to putting components together in an assembly line ,but more specifically ,it refers to creating a complete product that performs an intended function. Changes in the component are automatically reflected in the assembly i.e. The rebuild option will automatically take place or else it will ask the user to rebuild the

document.

ASSEMBLY APPROACHES IN SOLIDWORKS

• Top-Down Approach
• Bottom-Up Approach

RENDERING

Rendering or image synthesis is the automatic process of generating a photoreolistic or nan-photarealistic image from a 20 or 30 model using a computer program. The resulting image is referred ta as the render

ASSEMBLY OF AMERICAN CHOPPER

Assembly is most often referred to putting components together in an assembly line,but more specifically,it refers t< creating a complete product that performs an intended function.Changes in the component are automatically reflected in the assembly i.e.The rebuild option willautomatically take place or else it will ask the user to rebuild the document.

The American chopper is assembled using the feature called mates. Each and every part is mated with the other or the base part with specific relation.Some relations that are used to mate the parts of American chopper are mentioned below,

• Concentric
• Coincident
• Parallel
• Tangent
• Width
