So, you cannot find an STL of a model you want to print or you have a custom object in mind but don’t know if it can be printed. Well, fear not! This article is meant to show you how to design any object so that it can be printed with your desktop 3D printer! […]

## Furniture design – Dining table

With the aim of helping you try harder in the area of Computer aided furniture design, I am coming up today with this simple wooden dining table to model and render. The most interesting parts to model in this example are legs. The table top part is in itself the easiest part to model. In […]

## 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 voltage to be zero at the zero time. […]

## 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 before the object reach the ground. We will […]

## 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 what is taught in Math, in fact this […]
