In engineering, drafting, and technical drawing, geometric construction is fundamental for producing and analyzing shapes such as circles, triangles, polygons, and complex curves. It includes constructing points, lines, angles, triangles, circles, ellipses, parabolas, and determining foci of conic sections, as well as techniques like parallelism, perpendicularity, and bisection.

Dimensioned drawings in engineering graphics include all the necessary dimensions to make or manufacture a part, following proper dimensioning principles and standards to ensure clarity for engineers and manufacturers.

Lettering in engineering graphics should be neat, simple, and uniform, with all letters in capital form to improve readability and consistency. Guidelines should be drawn and used to prevent letters from drifting, and tools like the Ames® lettering template can help speed the process.

Conic sections in engineering graphics are curves obtained by intersecting a right circular cone with a plane at different angles. The primary types of conic sections include the circle, ellipse, parabola, and hyperbola, and their construction methods are detailed for design and analysis purposes.
