Working Drawing Components

A Working Drawing has the following usual components:

1. An Isometric Drawing showing the Part Numbers (or Part Labels).
2. An Exploded View (or Assembly Drawing) showing where the parts go and their fixtures.
3. An Orthographic Projection (First Angle) showing the overall and necessary minor dimensions.
4. If you can afford space for Part Drawings or useful Sectional Views to be included, go ahead and do so. Otherwise you must at least have those in of your development phase. Just think about the part drawings as a summary of your conclusions on the physical product project. Showing all the details, positions, trim lines and dimensions. (Note: Production Sequences and a Gantt Chart Production Plan need not be present in your presentation boards, however they MUST be included at the end of your development phase.
5. A Material List showing all the Part Numbers, the Materials used, the Dimensions and the respective Quantities.

Some Tips and Pointers:

1. Isometric Drawings: If the product has several components, especially those with components within each bigger component, you may consider drawing those components and label them seperately. It is impossible to draw all of them within (with lots of hidden lines) and attempt to number them off. That will be VERY messy and impossible to read. Finish off with a neat Exploded Drawing to show how each components come together.
2. Exploded Views: As long as the parts are aligned consistently (Isometric or Oblique) your exploded view should look neat. Not all parts can be aligned straight to its connection point. In this case you can draw your component slightly off, but use lines to create a 'path' to lead it to the connection point. The example above has everything aligned. For an 'off' example click here. In the linked example you will find a dowel that is not aligned.
3. Orthographic Projection: Leader lines should not touch the main drawing and should have a lighter line weight than the object. A good guide would be at least 10mm away from the drawn object. Spacing between dimension lines to the next should be consistent. A good guide would be at least 5mm away from the drawn object. Dimensions are usually written 'on' the dimension line. For vertical dimension lines, the dimensions are usually written on the left of the line following the orientation of the line.
4. Material List: Most common mistake is the written dimension. Lenght = the longest or the largest dimension. Followed by Width and the smallest dimension is the Thickness. It is worthy to note that numbering in the material list goes from '1' from the base up.
5. Do give a name for your project to be included as a 'Heading' for your Material List. Rather than "Material List' as your heading.
