2D, 3D . Mechanical Drawing Extraction Design

Concept of designing 2D and 3D mechanical drawings
Mechanical drawings, also known as technical drawings, are a product of the engineering industry. Technical drawing is a means of communication in engineering, it includes representations (such as projections, sections..), data clearly showing dimensions, technical requirements… Drawings. The technique is drawn according to a unified rule to represent the shape, texture, size, etc. of the object.

There are two common types of technical drawings that are 2D and 3D.

– Two-dimensional projection drawing (or 2D drawing): is the result of orthogonal projection (ie, projection perpendicular to the real object) in space down to the 2D plane.

– 3D drawing: is a drawing of objects presented in 3D space using parallel projection.

Classification of technical drawings
Part drawing: A separate drawing of each detail, often accompanied by an overall drawing. This drawing is used in fabrication, inspection, armoring and operation of machine parts.

Assembly drawing or structural drawing: Includes representations showing the shapes and structures of a group of parts or products and the data necessary for assembly and inspection. . It is mainly used in the design, manufacture and use of products.

Explosive drawing: Drawn in three-dimensional space with the parts disassembled and in the correct position ready to be assembled. It is intended to explain, advertise, and present to non-technical people.

Schema: A flat drawing consisting of simple symbols used to represent the operating principles of machines. Some popular schematic drawings such as: Machine principle structure diagram, electrodynamic circuit diagram, PLC control diagram…
The role of 2D, 3D . mechanical drawings

Mechanical drawings are likened to a guide with an extremely important role such as:

-Create quality products with high precision.

– Make the machining process easier and faster.

-After the product is completed, based on the mechanical drawing, the inspection and evaluation becomes simpler.

-Help consumers use products more safely and effectively.
