Challenge 5 : Concept Modeling of Car Bumper

1. title :- design 3D model of car bumper

2. objective

1. to generate 3D model of car bumper with the help of providing a blueprint.

2. to write preparation plan of model and tools features

3. introduction

bumper is using in a front and rear end of vehicles. accident time ,it is absorb impact and reduce impact rate. it has been making steel material for many years. after the many experiments behind the bumper, nowadays plastic type material is use in the bumper production.

in this project, we are generate model of car bumper and we are trying to match it with blue print. model have good quality of surface. further, we have writed in detail of model planning and tools information.

4. Design methodology

preparation plan of car bumper for generating model

1. model is divide in two part and only one part draw.

2. model is starting to draw from the outer to inner side.

3. second part generate by the mirror command

step for generate model

1. set a image on the software.

2. divide a bumper blue print as per same pattern

3. starte making from the one side only and other side we can use mirror and dublicet tool for making.

4. one side, we can start making from the outer bottom side to center side, curves and surface tools are use for making

5. check surface quality

6. mirror and dublicat command use for making other side

5. Description

1. Input image

File – import – canvas image – open browser and select photo

Another way is you can select image and hold right mouse button and move in the software screen (automatic image input in your need side).

2. Curve tools

Window – palette – curves tool – (line, blend, curve and many tools are their)

This tools use for network generation.

3. Surface tools

Window – palette – surface tool- (sphere, planar, skin, rail, square, multiple curve ).

Above tools are use for surface generation. Skin tools is create two side surface. Rail tools is crate two, three and four side surface. Square tools use for four side surface. And multiple curve tool use for more then 4 side surface.

4. joining of two curve

pick the curve - move – press ctrl + right button mouse or ctrl + alt + mouse middle button

5. Short key for pick, move, scale

Shift + ctrl + right button mouse

Shift + ctrl + middle button mouse

Shift + ctrl + left button mouse

6. Zoom in and zoom out

Shift + alt + mouse right button

Middle button move round

7. Project, trim tool

In the Palette - surface edit - project (any curve project on the surface)

In the Palette - surface edit – trim tools ( any portion cut by this tool)

8. Check surface quality

For quality of surface, Skin control bar, rail control bar and square control bar open and find check surface quality and also G0, G1, G2, G3 option through change quality of surface. Crvcvtr tool use for curve smoothness.

9.mirror and dublicet

edit - dublicate- select (mirror or object )

mirror is use for the copy of pattern and paste on the other side.

object use for mode is copy and rotation paste.

10. surface filet

this tool is making round and champer edge of the surface

palette - surface - filet

6. Model image

isometric view

front view

side view

top view

7. Conclusion

to conclude this, the model of car bumper is generate in the alias software.this model is good quality of suface. preparation plan and verious type of command are writed.
