Computer Aided Design & The 118 Elements
by Florin FODOR
In a mechanical design of an assembly made up of various parts it is often the case to make sure the functional elements are perpendicular to a reference. In GD & T this is called Perpendicularity Tolerance. Like parallelism, the perpendicularity tolerance is also an Orientation tolerance from the sub-group of Direction tolerances. Therefore for...

When you create a part as CAD data sure you can create a beautiful animation and virtually your part is perfect. But if you also intend to produce it, then without using GD & T for functional geometrical elements your CAD work remain only a virtual concept of something. It won´t work for real. Therefore...

Working with CAD platforms is an engineering area in which the ideas for new concepts and imagination are unlimited. It is impossible to create fixed standards about how to design new products, which design features to be used and how to strictly organize the model tree structure. This is entirely up to the mechanical designer.... Continue Reading →
Mechanical design exist for very long time. People have always created objects in different ways. Since the invention of CAD platforms mechanical design of things didn´t change the way how people imagine the objects they wish to create but these CAD platforms are today very powerful and even if it doesn´t really matter which such...

In manufacturing is often the case that parts are metalic and have a specific constant thinkness. In CAD of course no problem to design such a part but the work is much faster and effective is you don't design these parts using the standard way of doing it as Solid component but instead you do...

Depending on the project complexity the CAD work regarldless the CAD platform can be done in different apporaches. You can create a part completelly from skratch OR you can reuse some data already defined that can be reused for different other component parts of the project (for example to use data from a skeleton sketch...

For quite a long time mechanical parts were controled based on their regular forms such as planar form, cylindrical form or spherical form, but when parts become more complex in form such measurements based on simple features were not possible anymore. Such irregularly shaped profiled features couldn’t be geometrically controlled until 1966 when the first... Continue Reading →
The mechanical description of a part is usually done by using simple geometrical form features such as lines, planes, circles or cylinders. But in many cases mechanical parts have complex geometrical structures and their form deviations must be described more specifically. Therefore when your product is getting complex in form (e.g. automobiles, airplanes, ships) with... Continue Reading →
Designing Helical Shapes such are Springs with variable pitches sometimes is a challenge, mainly for the beginners. But things are very simple to do & control, CREO Parametric is an excellent tool for that and in this post I will show you how to do such design work. Step 1. Create New Part I click...

CREO Parametric it is indeed very Parametric CAD platform. Designing with CREO is super effective, it´s a pleasure to work with it, I love this software. It´s powerful, it´s fun, it´s user friendly and you can use it in any type of mechanical design projects. In this post I want to show you an example... Continue Reading →
