Mechanical Drawing Symbols

The vector stencils library "Bearings" contains 59 symbols of ball bearings, roller bearings, shafts, springs, gears, hooks, spindles, and keys.
Use it to design engineering drawings of machine tools and mechanical devices.
"A bearing is a machine element that constrains relative motion and reduce friction between moving parts to only the desired motion. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Many bearings also facilitate the desired motion as much as possible, such as by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts." [Bearing (mechanical). Wikipedia]
The shapes example "Design elements - Bearings" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Mechanical Engineering solution from the Engineering area of ConceptDraw Solution Park.

The vector stencils library "Dimensioning and tolerancing" contains 45 symbols of geometric dimensions and mechanical tolerances, geometric symbols, callouts, and text boxes and inserts.
Use these geometric dimensioning and tolerancing (GD&T) shapes to create annotated mechanical drawings.
"Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. GD&T is used to define the nominal (theoretically perfect) geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features."

The shapes example "Design elements - Dimensioning and tolerancing" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Mechanical Engineering solution from the ConceptDraw Solution Park.

The vector stencils library "Machines and equipment" contains 24 symbols of industrial machines and equipment.
Use the design elements library "Machines and equipment" for drawing plant interior design plans, manufacturing equipment layouts and factory floor plans using the ConceptDraw PRO diagramming and vector drawing software.
"Manufacturing is the production of goods for use or sale using labor and machines, tools, chemical and biological processing, or formulation. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale.
Modern manufacturing includes all intermediate processes required for the production and integration of a product's components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead.
The manufacturing sector is closely connected with engineering and industrial design." [Manufacturing. Wikipedia]
The shapes library "Machines and equipment" is included in the Plant Layout Plans solution from the Building Plans area of ConceptDraw Solution Park.
