Computer Aided Design & The 118 Elements

Mercury is a planet without much of atmosphere and its surface full of craters tells us about the great cosmic bombardment a.k.a. the Late Heavy Bombardment which is a hypothesized event thought to have occured approximatelly 3.9 billion years ago. It's not easy to find information about the early life of this globe, because Mercury... Continue Reading →
All the technology we have so far is based on materials available on our planet. At least for now. However at one point in time as technology continues to advance we might be able one day to exploit natural resources available in our Solar Sistem. Except Earth there are 4 bodies outhere we can consider... Continue Reading →
Runout is a very effective geometric tolerance which can be applied on any rotationally symmetrical parts. Depending on functional requirements, RunOut tolerance can be either measured on each individual point distributed arbitrary along the tolerated circular element which in this case is specifies as Circular RunOut tolerance. Or can be measured over the entire surface... Continue Reading →
Runout is one of the oldest and simplest concepts used in GD & T. Maybe as a child you stood your bicycle upside down on the ground and spun a wheel. If you fixed your stare on the shiny rim where it passed a certain part of the frame, you could see the rim wobble... Continue Reading →
When we travel by plane the cruising altitude is always above the clouds (at around 12.000 meters high). If your flight is on a full sunny day and you look downwards though the window at that height you either see the ground below or a white blanket of clouds. But that will quickly becomes boring,...

Inventing something new doesn' necessarily means that you come out with a revolutionaly product which nobody ever seen or though about before. Nowadays with so much tech available the possiblilty to really do so it exceptionally low. Yet improving an existing product adding features on it like no-one did before and create a memorable user... Continue Reading →
In this post I'll show you how to design a Viking Helmet made of 2 main componets :The Helmet Body and the Horn Body, which will make the final assembly in a Viking Helmet Product. Let's start with The Helmet!! THE HELMET STEP 1 Create new part STEP 2 Create 2 reference planes, each at... Continue Reading →
It's wonderful to know that new products can be produced faster with less effort and fewer errors. However, innovations are most useful when they are available to everyone and practices at General Motors, Volkswagen and the other mass producers, lag far behind. I know because myself I was doing this for years and during the... Continue Reading →
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 →
