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.
For putting to many dimension on top of the dimension!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Over-dimensioning refers to the practice of designing or specifying components, structures, or systems with dimensions or capacities that exceed the actual requirements for their intended use. This can lead to increased costs, unnecessary weight, and inefficient use of materials. While it may enhance safety or durability, over-dimensioning can result in waste and may not be the most effective approach in terms of resource management. Balancing safety and functionality is crucial to avoid over-dimensioning.
Things like General Dimensioning and Auto Dimensioning
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.
Methods of dimensioning include linear dimensioning, which specifies the size and location of features using straight measurements; angular dimensioning, which indicates angles between lines or surfaces; and radial dimensioning, which is used for circular features, providing the radius or diameter. Additionally, leaders and notes can be employed to clarify specific details. These methods ensure clear communication of sizes and relationships in technical drawings.
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.
