Surface Modeling in CATIA – Part 2

We have recently learned how we can create simple surfaces in Generative Shape Design workbench. In this tutorial, we are going to learn about operations carried on surfaces using CATIA. The tools we are going to require can be found in Operations toolbar. Operations Toolbar Most common

How to design a Buck converter in Matlab

A Buck Converter is a DC – DC step down voltage converter (can also be considered like step up current converter) . Here is how you can use Matlab to simulate a Buck converter (Note: In this post, we will consider switches as ideal) In order to

Graphic Design Software for Beginners

The popular Malcolm Gladwell 10,000 hour rule which states that it takes an individual approximately 10,000 hours to become a master of his or her craft is definitely one that must be taken to heart by anyone seeking to become a design guru and this is because

Surface Modeling in CATIA

CATIA is one of the most used software in automobile and aviation because of its advanced surface modeling techniques. Very complex surfaces can be modeled in CATIA. Popularly its Generative Shape Design workbench is used to design surfaces. One might wonder why surface modeling is so important.

Constraints used for a sketch in CATIA

Only a precise 2D geometry will create a precise 3D component. To create a precise 2D sketch in CATIA, we use constraints. What  does “constraint” actually means? It means that we are restricting the degree of freedom of the sketch. Consider, you want to constraint a line.

How to draw a Pulley in CATIA

This post shows you how to draw a Pulley in CATIA using Boolean operations. There are many reason you as a beginner should master how to use Boolean operation in CATIA. It is one of the preferred method used by CAD designers for the following reasons. It

RLC simulation in Matlab using Euler method

Here is a comparison between the Implicit Euler Method and the Explicit Euler method on a given RLC circuit. We will be using the two methods stated above to model the variation of the current in the circuitry below. RLC simulation in Matlab We consider the capacitor

Free fall – Modeling using Matlab

In this post, we will simulate the fall of an object dropped from a certain height in air. We will be using some numerical technique to find the time at which the speed of the object stop changing and to find out if this speed is reached

Boolean Operations in CATIA

Here is a quick explanation about Boolean Operations in CATIA and how you can use it in your project. It is hard to do without these techniques and it is always recommended (to beginners) to know how to use them early enough. A Boolean operation is similar to

How to draw a Soap case – CATIA

Welcome to one more 3D exercise. We will be having fun learning how to draw a soap case in CATIA. This exercise is designed to help you learn new commands from Part Design.   Most time for beginners, its easy to test your CAD skill on things

Catia Exercise – Creating a Flask

This exercise is designed to help you learn new commands like Multi-Sections Solid, Shell and more. The figure below shows a flask which we will use as goal to help us have a reason to play with CATIA today. This flask has nothing but basic rounded shape,

Drawing a circle in AutoCAD

Drawing a circle in AutoCAD is one of the most fundamentals while learning how to use the software. In AutoCAD there are many ways to draw circles, and all these ways depend on your inputs and the feature you want your future circle to have. The simplest

3D Exercise using CATIA

This is nice exercise to put to practice what we have learned so far. We are going to create in CATIA a pipe fitting component (elbow). After learning commands from Sketcher and Part Design workbench it should be easy to create this part. This elbow may be

How to create a Circular Pattern in CATIA

Pattern is one of the most common features used in CAD software. Here is a simple step by step tutorial about creating circular pattern of features in CATIA. Creating pattern of a single feature: Lets create a circular pattern of Holes on a disc like shown on

Draw a Wrench in AutoCAD

A wrench (also called a spanner) is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning Here is a short list of wrenches which you can have more details about

Creating a 3D part in CATIA

After learning few important commands from Sketcher and Part Design workbench, we can now create a simple 3D part in CATIA. In this post the focus is learning how to use other commands like Hole, Edge Fillet. Here is the 3D object we will try replicating using

Type of Gears

In technology, the word gear is used to designate a machine element having a purpose of transmitting/receiving power and motion from/to a rotating shaft by means of progressive engagement of their edges called teeth. In mechanical engineering, gears are generally used for power transmission and they are

Sketcher Workbench in CATIA

This post is to illustrate some important commands and in Sketcher Workbench. You need to remember that a part always starts with a sketch. The simple exercise below will serve as the object of our tutorial. If you are rather an AutoCAD user, you will find these

Basic commands in CATIA

CATIA (Computer Aided Three-dimensional Interactive Application) is one amongst CAD software that was initially developed to help design aviation systems. It is today one of the leading CAD software in aviation and automobile industry. Here is a very basic “Demo” about Basic commands in CATIA. In this

Easy rendering software

Rendering is one of the most time consuming task while working on a project. Sometime rendering a model can take way too long, and in some case you have to wait for hours just to notice the resulting image of your rendering is not good enough and
