About Engineering graphics

Engineering Graphics is a field of study that deals with the process of creating technical drawings and illustrations. This type of drawing is used in a variety of fields, including architecture, engineering, and manufacturing. Engineering graphics are used to communicate ideas and designs to others who may not be able to understand the technical language used in blueprints or schematics.

There are a few things to keep in mind when creating engineering graphics. First, the drawing should be legible and easy to understand. Second, all lines and symbols should be precise and accurate. Third, the drawing should be to scale so that it can be used for measurements or construction. Finally, Engineering Graphics should be created using software that is compatible with the software used by the Engineering department.

Creating engineering graphics is a skill that takes time and practice to perfect. However, with a little patience and attention to detail, anyone can learn how to create technical drawings.

Here are a few tips to help you get started:

  • Use software that is compatible with the Engineering department.
  • Make sure all lines and symbols are precise and accurate.
  • Pay attention to detail.
  • Practice, practice, practice!

With a little time and effort, you'll be creating engineering graphics like a pro in no time.

Following are some of the multiple choice questions on the Engineering graphics with answers that will help the students in developing their knowledge.
