Conclusion

1.      Why is placement of your dimensions so important?

In order to prevent a messy diagram of the object in question. For example intersecting lines, repeated dimensions are a hassle to look over.

2.      Why do designers need to fully dimension a part?

In order for other designers to not assume or not know the length of certain parts.

3.      What does it mean when a sketch is over dimensioned?

Over dimensioned sketching is when proportions are not constrained therefore causing deformity in the drawing.
