Photo Realistic Rendering

MODELING, ASSEMBLY, PHOTOREALISTIC RENDER OF AN AMERICAN CHOPPER

OBJECTIVE

Main objective of this project is to Create a photo-realistic Conceptual model of an American Chopper using solid works. By creating part drawings, converting them to 3D models, assembling the created parts and finally giving it a photorealistic view by rendering the model using Photoview-360.

INTRODUCTION SOLIDWORKS

Solid works is a 3D-Modelling Computer Aided Design (CAD) and Simulation based software. To create a 3D Model, it uses the parametric future based approach. (Developed by PTC) by taking the inputs from the user

AMERICAN CHOPPER

A chopper is a type of custom motorcycle which emerged in California in the late 1950s. The chopper is perhaps the most extreme of all custom styles, often using radically modified steering angles and lengthened forks for a stretched-out appearance. They can be built from an original motorcycle which is modified (chopped) or built from scratch. Some of the characteristic features of choppers are long front ends with extended forks often coupled with an increased rake angle, hardtail frames (frames without rear suspension), very tall "ape hanger" or very short "drag" handlebars, lengthened or stretched frames, and larger than stock front wheels

DESIGN METHODOLOGY

Idea is the primary requirement to design/model any product

MODELING

American Chopper consists of

• Front Fender
• Chassis
• Rear Fender
• Front fork
• Gas tank
• Oil Tank
• Front wheel
• side stand
• Rear Wheel

The major Tools/Features used in the solid works for modeling the chopper were

1. Creating a 2D sketch: A 2D sketch is the base to create a 3D model. It is usually created on the X-axis & Y-axis. This includes lines, circles, rectangles, splines, etc..

The current status of a sketch is displayed in the lower right corner of the screen.

Fully Defined = Black,Under Defined = Blue, Over Defined = Red

Geometric relation: Geometric relations ar one of the most powerful features in SOLIDWORKS.They're used in the sketch level to control the behaviors of the sketch

entities when they are moved or rotated and to keep the associations between one another

Solid Extrude: It extrudes a sketch or selected sketch contours in one or two directions to create a solid feature

• Create a sketch. You can use a closed profile sketch or an open profile. For cuts, open profile sketches are only valid for Blind or Through All end conditions

Click one of the extrude tools Insert >Boss/Base > Extrud

. Click ok

.Extrude cut: Extrude cut is a feature which helps to remove materials from the 3D model. It is just opposite to extrude boss/base feature, because it cuts a sketch profile while extruding. It can cut in both directions and mainly used for creating holes, channels, slots etc.

• Sketch on planes and/or planar surfaces

. The sketch should be closed and defined

. Then select the cut extrude command, to cut the solid

5.Revolve Boss: Revolves a sketch or selected sketch contours around an axis to create a solid feature.

• Create a new 2D sketch.
• Create all solid sketch geometry on one side of the axis. . Choose Revolve Boss/Base from the features menu.

Pick the axis you wish to use for the revolve.

• Specify direction and angle.
• Acce the Feature

6.Revolve Cut: Cuts a solid model by revolving a solid profile around an axis.

7.Swept Boss: This feature sweeps a closed profile along an open or closed path to create a solid feature.

• Create a line or spline sketch.

Select the profile need to extrude

• Select the path with extrude need to be done

8.Loft: The loft feature creates a shape by making transitions between multiple profiles and guides curves thus allowing to create complex geometry with a single tool.This feature can be used in both solid as well as surface modelling.

9.Dome: A dome is a rounded vault forming the outside face of a body or structure,

typically with a circular base.

Click Dome on the Features toolbar, or click Insert > Features > Dome.

• Select one or more planar or non-planar faces. Set a value for the distance by which the dome expands.
• Click to create a concave dome

10. Curve driven: The Curve Driven Pattern tool allows you to create patterns along a planar or 3D curve. To define the pattern, you can use any sketch segment, or the edge of a face (solid or surface), that lies along the plane. You can base your pattern on an open curve, or on a closed curve, such as a circle.
11. Linear pattern: Use linear patterns to create multiple instances of one or more

features that you can space uniformly along one or two linear paths.

12. circular patterns: Use circular patterns to create multiple instances of one or more can space uniformly around an axis.

The Offset entities tool is as simple as clicking the geometry after initiating the command

17.split: Use the Split feature to create multiple parts from an existing part. You can create separate part files, and form an assembly from the new parts.

. Click Split (Features toolbar) or Insert > Features > Split.

• In the PropertyManager, set the options.

Callout boxes appear in the graphics area for up to 10 bodies at one time. Click Next 10 or Previous 10 to scroll through all the callout boxes for a part.

• Under Resulting Bodies, select the bodies to save under, or click Auto-assign Names.

All of the saved bodies appear in the graphics area and are listed in the FeatureManager design tree under Solid Bodies. The software automatically names all bodies. You can change the names.

• Double-click the body name under File, type a name for the new part in the dialog box, then click Save.

The new part name appears in the Resulting Bodies list and in the callout box. Unsaved bodies are not split and remain with the original part.

If you clear the check box for a split part after you save it, that part is no longer

dialog box, then click Save.

The new part name appears in the Resulting Bodies list and in the callout box. Unsaved bodies are not split and remain with the original part. If you clear the check box for a split part after you save it, that part is no longer saved as a separate entity. It remains with the original part.

. Click ok.

18.Solid Merge/Combine: In a multibody part, you can combine multiple bodies to

create a single body.

. Click Combine. (Features toolbar) or Insert > Features > Combine.

• In the Property Manager, under Operation Type, select Add.
• For Bodies to Combine, select the bodies to combine. You can select bodies in the graphics area or the Solid Bodies....

. Click Show Preview to preview the feature.

. Click ok.

19.project curve: You can project a sketched curve ontera model face to create a 3D curve. You can also create a 3D curve that represents the intersection of two extruded surfaces generated by creating sketches on two intersecting planes.

Use selection to create a curve that represents the intersection of sketches from two intersecting planes.

• Create a sketch on each of two intersecting planes, closing each sketch when you are done.

19.project curve: You can project a sketched curve onto a model face to create a 3D curve. You can also create a 3D curve that represents the intersection of two extruded surfaces generated by creating sketches on two intersecting planes.

Use selection to create a curve that represents the intersection of sketches from two intersecting planes.

• Create a sketch on each of two intersecting planes, closing each sketch when you are done. Align the sketch profiles such that when they are projected normal to their sketch plane; the implied surfaces will intersect, creating the required result.
• Under Sketch to Project, select both sketches in the flyout FeatureManager design tree or the graphics area.
• Select Reverse projection to reverse the direction of projection.
• Select Bi-directional to create a projection that extends on both sides of the sketch

. Click ok.

20.Converting Entities: You can create one or more curves in a sketch by projecting an edge, loop, face, curve, or external sketch contour, set of edges, or set of sketch curves onto the sketch plane.

• In an open sketch, click a model edge, loop, face, curve, external sketch contour,

In an open sketch, click a model edge, loop, face, curve, external sketch contour,

set of edges, or set of curves

. Click Convert Entities (Sketch toolbar) or Tools > Sketch Tools > Convert Entities

. In the Property Manager, click Select chain to convert all contiguous sketch entities.

. Click ok.

21.Shell; The shell tool hollows out a part, leaves open the faces you select, and creates thin-walled features on the remaining faces. If you do not select any face on the model, you can shell a solid part, creating a closed, hollow model. You can also shell a model using multiple thicknesses

. Click Shell (Features toolbar) or Insert > Features > Shell. • Set Thickness to set the thickness of the faces you keep.

• Select one or more faces in the graphics area for Faces to remove
• click ok.

22.Mirror: This allows to mirror features, faces & bodies along a face or a plane.

• click Mirror (Features toolbar) or Insert > Pattern/Mirror > Mirror.
