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

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

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

Different CAD views

This post is all about views in technical drawing. This is a reminder, specially for those who will be heading to those AutoCAD 3D tutorials I published here earlier. There is need to remember some basic principles about technical drawing while using any CAD software, here we

AutoCAD Trim

Trimming is one of the first tools one should learn how to use while operating on AutoCAD. The AutoCAD TRIM command is a thing you can barely end a project without using. Why using the TRIM command in AutoCAD? The TRIM command helps you trim object such

AutoCAD 3D Tutorial

One step closer to reality! Looking for some basic AutoCAD 3D exercises? Here are some exercises designed to help you practice and learn how to draw in 3D in AutoCAD. Before diving into this post, make sure you digest what is shown in these 5 3D demo:

Using the command window in AutoCAD

The command window in AutoCAD, for the less I can say, is where all what you are doing is being recorded. It is also the means AutoCAD uses to communicate with you. It is important to know how to use it. All icons are shortcut of commands.

How to draw a spring in AutoCAD

Drawing a spring in AutoCAD is relatively easy using the SWEEP command. If you had a look at how I started working on AutoCAD 3D you would know a little about the SWEEP command. But before getting to using the SWEEP command, I would like to go

UCS in AutoCAD

UCS stands for User Coordinate System and is represented by the object on the left down corner of your AutoCAD windows. This is a crucial tool for 3D design in AutoCAD. This is why in this post I will use the simple figure below to help you

Basic Tools in 3D in AutoCAD

While a lot will give you many reason why AutoCAD is not the indicated software for 3D I want to deliver in this post the concept of 3D in AutoCAD and what you should be thinking about if 3D is a total new concept for you. 3D

Annotation scaling in AutoCAD

Here is how to work with Annotation scaling in AutoCAD Sometime, annotations might be either too big or too small compared to dimensions you used in your project. Here is how you can change annotation features in AutoCAD, including text, and color The DIMSTYLE command help you
