The layout of an engineering drawing
It is important that you follow some simple rules when producing an engineering drawing which although may not be useful now, will be useful when working in industry.
All engineering drawings should feature an information box. An example is shown below.
Common information recorded on an engineering drawing
- TITLE
- The title of the drawing.
- NAME
- The name of the person who produced the drawing. This is important for quality control so that problems with the drawing can be traced back to their origin.
- CHECKED
- In many engineering firms, drawings are checked by a second person before they are sent to manufacture, so that any potential problems can be identified early.
- VERSION
- Many drawings will get amended over the period of the parts life. Giving each drawing a version number helps people identify if they are using the most recent version of the drawing.
- DATE
- The date the drawing was created or amended on.
- SCALE
- The scale of the drawing. Large parts won't fit on paper so the scale provides a quick guide to the final size of the product.
- PROJECTION SYSTEM
- The projection system used to create the drawing should be identified to help people read the drawing. (Projection systems will be covered later).
- COMPANY NAME
- Many CAD drawings may be distributed outside the company so the company name is usually added to identify the source.
