1. Line work: Creating clear and consistent lines is the foundation of engineering drawing. Lines can communicate different meanings based on their weight, style, and placement. Understanding different line types like object lines, hidden lines, centerlines, etc. is very important.
2. Dimensioning: Dimensioning is the process of adding numerical values to a drawing. It is important to understand the types of dimensions, such as linear, angular, and radial, and the proper placement of dimensions on the drawing.
3. Projection: Projection is the process of creating a two-dimensional representation of a three-dimensional object. Understanding orthographic projection, isometric projection, and perspective projection is necessary for accurately representing objects on a drawing.

1. Sketching: Sketching is the process of quickly drawing out an idea or design concept. It is an important skill for brainstorming and communicating ideas with others.
2. Use of tools: Using tools such as a compass, ruler, protractor, and templates can help to create accurate drawings. It is important to understand how to use these tools properly to create clean and precise lines.
3. Lettering: Lettering is the process of adding text to a drawing. The letters must be consistent in size and style to ensure readability and professionalism.
4. Scaling: Scaling is the process of reducing or enlarging a drawing to fit a specific size. Understanding how to scale a drawing is important to ensure that the drawing is accurate and fits the intended purpose.

By mastering these basic drawing techniques, an engineer or designer can create accurate and professional engineering drawings that effectively communicate technical information.
