Answer :

Orthographic drawing is a method of representing three-dimensional objects in two dimensions. It consists of a series of principles that guide the creation of detailed and accurate representations. Here are 10 principles of orthographic drawing:

Represent the object in two dimensions.Utilize first angle or third angle projection.Ensure that the scales and dimensions are accurately depicted.Show all necessary views (front, top, side).Include hidden lines for features not visible.Apply dimension lines and notations for clarity.Use hatching for sections to show material.Align the views correctly relative to each other.Make sure lines are clean and sharp for precision.Maintain uniformity in line types and weight.

Orthographic drawing is an essential skill in fields such as architecture, engineering, and design, where precise and clear representations are vital. The key is to provide a two-dimensional representation of a three-dimensional object using a set of conventions that enable the viewer to understand the shape, size, and features of the object. The first principle is about representation in two dimensions, creating a flat image that captures the object's shape. The second involves selecting a projection method (first or third angle) that dictates how the views correspond to the object. The third principle emphasizes the importance of scale, ensuring that all measurements are to scale for accurate fabrication or construction. Showing all necessary views helps provide a complete understanding of the object from various angles. Hidden lines are included to show parts that are not directly visible, while dimension lines and notations provide necessary measurements and instructions. Hatching indicates different materials when a section view is used. Aligning views correctly ensures that the object can be visualized as intended from different angles. Clean and sharp lines, along with consistent line types and weights, are important for the drawing to be easy to read and interpret.
