computer aided design

Introduction

This week deals with the various software that can be used to design in 2D and 3D. So this week's goal is to learn more about various design software and make a 2D/3D model of our final project. Neil has introduced many CAD softwares Also go through this is the link of cad software

3D

There are so many 3D design software like Sketchup, Solid works, Rhino, Antimony, etc. Amoung these Sketchup may be the most simple tool for a beginers I think. The UI and the options seems to be very simple. When we consider assembly of machine parts (drawing the parts and then assembling these parts like a real machine) solid works may be the most powerful tool. Most people who deals with machines and machines parts use Solidworks.

SolidWorks is a solid modeling computer-aided design (CAD) and computer program that runs on Microsoft windows. SolidwWorks is published by Dassault Systemes. SOlidWorks is closed source,the minimum cost of a single license is about $4000USD.

the second in 3D is colled freeCAD software.

FreeCAD is a parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD is open-source and highly customizable, scrip table and extensible.

that are freeCAD software.

i can start to design the knob in freeCAD.

freeCAD dimensions.

in that shematics we can design the circle line and its define the radius of each circle line then that radius is called the dimensions in free cad that all part that all we need the master skech in our design.

now we can close the skech in free cad and then we can call the skech master.

we can add the height of 25 millimeter in my sketch

we can create the datum plane.

that are the final design of the knob

2D

Two-dimensional space is a geometric setting in which two values (called parameters) are required to determine the position of an element (i.e., point). In Mathematics, it is commonly represented by the symbol R2.

illustrator

Illustrator is an image processing software. This application allows you to create, edit images.with illustrator you can Create and beautify photos, images, 2D artwork and other content..
