For putting to many dimension on top of the dimension!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You are putting too many dimensions on it. For example, if there is a L shaped sketch and you dimension from the bottom of the L to just above the horizontal part, and then you dimension the vertical part from the end point of the last dimension you'd be okay. But, if you dimensioned both of those lengths and then the total length you would be over dimensioning the sketch.

Things like General Dimensioning and Auto Dimensioning
Dimensioning standards are standards on how to dimension a working drawing.
Tabular dimensioning
It show dimension of given dig. Ex. length meter etc. > chain dimensioning as opposed to datum dimensioning. chain dimensioning: 4 holes in line on a drawing, first hole position dimensioned from the edge, remainder dimensioned from the centre of the previous hole. datum dimensioning: all holes dimensioned from the edge. the cumulative tolerance build up on the chain dimensioning allows for greater overall tolerance build up.

Over-dimensioning refers to the practice of designing or specifying components, systems, or structures with dimensions or capacities that exceed the actual requirements for their intended use. This can lead to increased costs, material wastage, and inefficiencies, as larger or more robust solutions are often more expensive and may not provide additional benefits. While it can enhance safety margins, excessive over-dimensioning may detract from optimal performance and sustainability. Balancing adequate safety with cost-effectiveness is crucial in engineering and design.
Baseline dimensioning is a method of dimensioning in technical drawings where all dimensions are referenced from a single baseline, reducing the chance of errors due to accumulation of tolerances. It helps to maintain clarity and consistency in the layout of dimensions on a drawing.
Using a fixed common reference point ensures consistency and accuracy in dimensioning, making it easier for multiple people to interpret the dimensions on a drawing or sketch. It eliminates confusion and errors that can arise when referencing dimensions from different starting points, resulting in more precise and reliable measurements.
they are used by showing where it is
