Geometric Dimensioning and Tolerancing (GD&T), is a system Allowance for a specific variation in the size and geometry of the part

What is Geometric Dimensioning & Tolerancing (GD&T)?

Geometric Dimensioning and Tolerancing (GD&T), is a system Allowance for a specific variation in the size and geometry of the part, in other words ;
“Geometric Dimensioning and Tolerancing (GD&T) is a Set of rules, the structured language of symbols and definitions that allow the geometrical features of mechanical parts to be defined according to functional limits of imperfection.”

When do Tolerances become important?

Assemblies : Parts will often not fit together if their dimensions do not fall within a certain range of values.
Interchangeability : If a replacement part is used, it must be a duplicate of the original part within certain limits of deviation. • The relationship between functionality and size or shape of an object varies from part to part.

Why Use Geometric Dimensioning & Tolerancing (GD&T)?

GD&T: An International Language
Geometric dimensioning and tolerancing is an international language or instructions used for machine or part drawings to accurately describe a part.
GD&T consists, set of symbols, rules, definitions, and conventions that can be used to describe the size, form, orientation, and location tolerances of part features.
It is a standard Language that enables designers to understand a drawing & “what it Means”, Which helps in improvement & Production of a design. Due to the international standard it GD&T Language provide helps to achieve uniformity in drawing and interpretation.

What is CAD?

The full form of CAD is Computer-aided design, which means creating, modifying, analyzing and optimizing any design using a computer. CAD Softwares are used by designers to enhance productivity and make precision designs. CAD Softwares are used by across industries like Manufacturing, Automobile, Aviation, electrical, civil, architectural, etc. CAD design engineer used CAD Software to make 2D and 3D design to create models prototypes 3d printing and also used for Analysis.

CAD is used:

To Produce 2D or 3D Engineering drawings in Mechanical, civil, architectural or electrical industry.
In Mechanical Industry, CAD is used to Creating concept design, Product Layout, strength and dynamic analysis of assembly.
In civil and Architectural industry, CAD is used to create the 2D layout, plan, 3D elevations, Building Information Modelling (BIM), estimation, costing and rendering.

Types of CAD Softwares ?

CAD Softwares are broadly 2 types.

2D CAD tools. These were developed in the early 1970s and rely on basic geometric shapes such as circles, rectangles, lines, etc. to create flat drawings.
3D CAD tools. More advanced software that was developed in the 1980s. It has improved graphics display capabilities that enable you to create realistic 3D images. You need professional training to master this software.

3D CAD software can be further categorized into:

Wire-frame models. These have become old-fashioned and they create skeleton-like models with arcs and lines.
Surface models. These create models by joining 3D surfaces. The background is not visible which makes the surface models quite realistic.
Solid models. The most useful CAD models. They are a step up from surface models as they have added properties such as density, volume, and weight that make them resemble real physical objects. Solid models are utilized as prototypes to work on engineering designs.

What is GD&T?

GD&T is abbrivition of Geometric Dimensioning and Tolerancing. GD&T is an engineering language based on symbols to define the allowable deviation of feature geometry in any engineering drawings and models.
