What are the parts of mechanical drawing?
Mechanical drawing typically consists of several key elements:
Title Block: This is located in the lower-right corner of the drawing and contains information such as the title of the drawing, the name of the drafter or designer, the date of creation, revision history, and any other relevant details.
Revision Block: Often located near the title block, this section records any changes made to the drawing over time, including the date of revision and a brief description of the changes.
Drawing Views: These are the main graphical representations of the object being depicted. Common types of views include orthographic projections (front, top, side views), isometric views, section views, and auxiliary views.
Dimensions: Dimensions are essential for communicating the size and proportions of the object. They are typically indicated using lines, arrows, and numerical values, and they can include measurements such as length, width, height, angles, and tolerances.
Notes and Annotations: These provide additional information or instructions related to the drawing. They may clarify specific features, materials, manufacturing processes, or assembly procedures.
Symbols and Labels: Symbols are used to represent features such as fasteners, surface finishes, welds, and geometric tolerances. Labels and callouts identify specific components or areas of interest within the drawing.
Section Views: In cases where internal details need to be shown, section views are used to cut away a portion of the object to reveal its internal features.
Bill of Materials (BOM): A list of all the components and parts required to build the object depicted in the drawing. It typically includes part numbers, descriptions, quantities, and sometimes additional information such as material specifications or supplier details.How to draw mechanical drawing?

How to draw mechanical drawing?
Drawing mechanical drawings involves precision and attention to detail. Here’s a general guide to get you started:
Gather Materials: You’ll need a drawing board, mechanical pencils, rulers, compasses, protractors, erasers, and any specific drafting tools required for your project.
Understand the Requirements: Mechanical drawings typically follow specific standards like ANSI (American National Standards Institute) or ISO (International Organization for Standardization). Make sure you understand these standards and any specifications for the drawing you’re creating.
Start with Orthographic Projection: This is the basic technique used in mechanical drawings to represent a three-dimensional object in two dimensions. Begin by drawing the object from different viewpoints (front, top, side, etc.) using orthographic projection.
Use Proper Scales: Decide on the scale of your drawing. Common scales include 1:1, 1:2, 1:5, etc. Ensure that all parts of the drawing are scaled proportionally.
Add Dimensions: Dimensions are critical in mechanical drawings as they provide the necessary measurements for manufacturing or assembly. Use dimension lines, extension lines, and dimension numbers to indicate the size and location of features.
Include Annotations: Annotations provide additional information about the drawing, such as material specifications, part numbers, tolerances, and other important notes. Place these annotations strategically so they’re clear and not cluttered.
Detailing: Add further details such as fillets, chamfers, holes, threads, and any other features that are essential for understanding the design.
Title Block: Every mechanical drawing should have a title block that includes information such as the title of the drawing, the name of the designer, date of creation, scale, and any other relevant details.
