3. Computer Aided design¶

Model (raster, vector, 2D, 3D, render, animate, simulate, …) a possible final project, and post it on your class page.

What is C.A.D.?¶

“In week 3 we are introduced computer aided design (CAD). CAD is divided in 2 parts: - 2d design - 3d design = 3D Modeling

2D Design : 2D design is the creation of flat or two-dimensional images for applications such as electrical engineering, mechanical drawings, architecture and video games.

3D design : 3D modeling is the process of developing a mathematical representation of any surface of an object (either inanimate or living) in three dimensions via specialized software. The product is called a 3D model. We can use those models to ideation and prototyping(simulation).

Parametric vs Direct Modeling

Background¶

CAD is new for me, and as per instruction we have to select 2 or more software to work on 2D, 3D. It is a bad condition to explore the CAD software for graphics designer. I contact to mechincal department of my college. They help me to perfer the software whih I used in week 3 and in future also.

Software decided to learn this week:¶

Rhino - 90 Days Evulation
Fusion 360 - Student Licence
Autodesk Inventor - Student Licence
GIMP - Open Source
Inkscape - Open Source
CorelDraw - Purchase
Adobe Illustrator - Friend’s Licence

Rhino¶

Rhino can create, edit, analyze, document, render, animate, and translate NURBS curves, surfaces, and solids, point clouds, and polygon meshes. There are no limits on complexity, degree, or size beyond those of your hardware.

Simple Square with some measurement

fillet name tool is used to make curve

Fillet both the side with equally curve

Take a mid point and make a line . Then select line and make arry of the single line.

using many types of circle and arcs, make any object

Joining the lines and group the objecct\

Revolove the 2D Images both the side

Give it a solid surface

Put it as materialitics

Steel Material

Render Images with two sub branch of options

My Workflow¶

Basically I am nurb in CAD is i started with rhino.
Think about various product, after all i got idea to make bottle.
Bottle is basically group of all shapes and various tools.
It’s include fillet, join, cap, explore, split, rebeld surface, sweep, points, softeditsurface, softeditpoint, environment, etc.

Another Example

points
circle
line
rec
polyline
interpcrv
crv
length: length of line or curve
distance: distance between two points
area: area of a surface
move
copy
rotate
extend: make a curve longer
scale1D: good for resizing lines
scale2D: good for resizing flat shapes
scale (you can indicate with numbers the scaling factor)
mirror: copy/move and rotate; can be used to reflect or flip
array: orient and copy
orient: good when the thing you’re moving is asymmetric/sided/chiral
offset: scale and copy
fillet: round sharp corners
planarSrf: turn a closed curve into a surface
loft: make connecting surface between two lines/curves
extrude
make2d: create 2d shape of selected surface, according to current view
unrollSrf: turn a volume into flat components
dupBorders: produce curve from boundary of a surface
explode
split: divides a line/curve/surface at a center point/line/intersective-surf/curv
trim: split + delete
extend
rebuild
curveBooleon
divide: dividing lines/curves into equal parts
rebuild: either turn cuves into lines or make ugly curves pretty curves
layer: show layers window (use many layers!)
show/hide: select an object and temporary show it or hide it
setPt: set all X and/or Y and/or Z points of a geometry to a new value
zoom: zoom set, show you just the selected object in the active transport
join: make one curve/surface out of many segments
explode: separate segements of a curve/surface
group
orientCameraToSurface

Fusion 360¶

Fusion 360 unifies design, engineering, and manufacturing into a single platform that works on both PC and Mac.

In this Documentation, we will cover: - How to quickly and easily create a design - How to analyze a design for product performance - How to manufacture a design using built in CAM capabilities.

If and when possible, we will do our best to customize the demonstration to the use-case.

Autodesk Inventor¶

Inventor allows 2D and 3D data integration in a single environment, creating a virtual representation of the final product that enables users to validate the form, fit, and function of the product before it is ever built.Autodesk Inventor includes powerful parametric, direct edit and freeform modeling tools as well as multi-CAD translation capabilities and in their standard DWG™ drawings.

Inventor uses ShapeManager, Autodesk’s proprietary geometric modeling kernel.

Autodesk Inventor competes directly with SolidWorks, Solid Edge, and Creo

This is all about 11-12gb Software It contains many software of autodesk. Inventor Professional 2019 Installed Interface Option of plans are available in many condition Image + Object = Its quick easy then Fusion 360, but many feature are same!

Adobe Illustrator¶

Adobe Illustrator is a vector graphics editor developed and marketed by Adobe Inc. Originally designed for the Apple Macintosh, development of Adobe Illustrator began in 1985. Along with Creative Cloud Illustrator CC was released.The latest version, Illustrator CC 2019, was released in October 2018 and is the 23rd generation in the product line. Adobe Illustrator was reviewed as the best vector graphics editing program in 2018
