Then by mid of 20th century television started to gain in popularity and watching a movie at home has become very much a new common habit to enjoy our leisure time. However the first TV sets were...

MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the PERPENDICULARITY tolerance?
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...

MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the PARALLELISM tolerance?
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...
