How to Read a Mechanical Blue Print

Follow a few guidelines to understand the basics of blueprints.

Engineering requires deep knowledge of how things work, and part of the challenge is understanding the blueprint you use to build your project. Mechanical engineers must know how to read blueprints to do their jobs properly. You can read these blueprints by following some important guidelines.

Instructions

1. Examine the blueprint legend and carefully identify the meaning for each symbol. If there is no legend, contact the creator of the blueprint for a more detailed explanation of the document.

2. Learn the meaning and dimensions of the other lines, abbreviations, measuring tools and spacing within the blueprint. Use the legend as a guide to help you understand these different features.

3. Work with experts in the relevant field that you are examining. Mechanical blueprints cover a number of different areas in a facility, including its plumbing, heating, air conditioning, ventilation, lighting and drainage

4. Refer to safety and design codes for the relevant area of mechanical engineering. For example, if you are creating a heating unit, you must apply a filter system to ensure there is adequate capacity to prevent dust buildup and provide effective ventilation to the unit and ducts.

5. Build a model of your project, if possible. This will help you anticipate problems and understand the construction methodology. Create a mental image of the distances between different objects in the actual project.

6. Follow the blueprint using the dimensions, model and expertise you have acquired.
