Things to include and not include
What is included in an assembly drawing?
When deciding what to include in an assembly drawing remember;
- The purpose of an assembly drawing is to show how the individual parts fit together. It is not used as a manufacturing print.
- The assembly drawing should not look overly cluttered. Some lines that are necessary in a detailed drawing may be left off the assembly drawing to enhance clearness.
Do we include hidden lines?
They should be used wherever necessary for clearness. They should be left off when they impair clearness. When a section view is used, hidden lines should not be used in that view.
Do we include dimensions?
As a rule, dimensions are not given on assembly drawings. If dimensions are given, they are limited to some function of the object as a whole.
