Common mistakes in land surveying can have significant consequences and typically fall into three categories:

Instrumental Errors: These occur due to imperfections or faulty adjustments of the instruments used for measurement. 

Personal Errors: These arise from human factors such as imperfect vision or errors in judgment while observing and manipulating instruments. 

Natural Errors: These are caused by environmental factors like temperature, humidity, gravity, wind, refraction, and magnetic declination. If not properly accounted for during measurements, they can lead to inaccurate results. 

Land survey CAD drafting requires meticulous attention to detail and adherence to best practices to avoid common mistakes. By prioritizing accuracy in measurements, maintaining thorough field notes, complying with legal requirements, and implementing robust quality control measures, surveyors can mitigate the risk of errors and deliver precise and reliable survey documents.
