Among the 14 used GD & T symbols in the category of Location Tolerances there are 3 types. 1. The Position Tolerance 2. The Concentricity Tolerance 3. The Symmetry Tolerance From these 3 tolerance types, only the Position Tolerance is often used as it is also easy to measure. The other 2 are in general... Continue Reading →
The functionality of a part in an assembly is usually well defined by the 4 form tolerances (straigthness, flatness, circularity and cylindricity) and among the orientation tolerances by the 3 most frequent ones: the position, the perpendicularity and the parallelism tolerance. Yet we have 14 different types of tolerances in total, which can be anytime... Continue Reading →
A wheel rim design can be done in different ways, depending on the wanted pattern and the used CAD software. In this example I show you a version of Wheel Rim used on AUDI cars and how to do it in CREO Parametric CAD software. A wheel rim can also be done in 1 piece... Continue Reading →
After, Water and Tea, the 3rd one most consumed refreshment drink must be the COFFEE. At some point I am tempted to put coffee in the same position with tea as both being the 2nd most consumed drinks on the planet, but I guess Tea better deserves the 2nd place. Like Tea, making a good... Continue Reading →
I am sure most people will say, what's so much of science to make a good tea? Should not be a big deal, simply take a bag of tea or tea leafs and put it in a cup with boiled water, then add some sweetener and done. The tea is ready. Right? Well... things are... Continue Reading →
As we've already seen in the previous posts, The Bug Rover is made of various components. In this post we'll put everything together in the final product. But before to create the final assembly, let's create first the Sub-Assembly called Carterpilar which will be later used as multiple instances for the final assembly. Let's start:...

In this Part of Bug Rover design work, I'll show you the 3 main components of the Carterpilar assembly. These are: The Star Gear, The Gear Cap, The Wheel and The Carterpillar. Let's start: THE STAR GEAR STEP 1 Create a new part STEP 2 On Front plane draw the following sketch and revolve it... Continue Reading →
In this 2nd part of design work for the Bug Rover, I'll show you the next 2 main components: The Lever and The Lever Cap. Let's start: THE LEVER STEP 1 Create new part STEP 2 Create the following 2 sketches: STEP 3 Use the previous 2 sketches to create a Project Curve STEP 4... Continue Reading →
A rover design work implies a lot of details and components. In this article I want to present you a simplified version of a reover concept I did, which is inspired from the insects world. It really looks like a bug, so I name it Bug Rover. I will only put here the main bodies... Continue Reading →
A Katana Sword is not just a regular object. It is a symbol of honor and respect, it's almost like a medal. Therefore it must have a specific way of storing. The most common is a wooden support which serves either for the sword inside the scabbard or both the sword and scabbard seperatelly. In... Continue Reading →
