Tech Drawing Best Practice

• Show dimensions in an organized way, and ideally corresponding to actual location from which a person would measure. This makes the tech drawing highly functional, as opposed to requiring a lot of parsing of information.
• Show minimum required information to eliminate time spent on irrelevant information
• Create user-specific tech drawings. Someone with experience will likely require less information.
• Show additive dimensions (length of 132" when 89 and 43 were already measured) only if they are obviously useful for quality control.
• Distinguish quality control measurements from functional measurements
• Use fiducials in priority over actual dimensions, unless dimensions are required (for quality control or other purposes)
