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.

What are methods of dimensioning?
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.
What is baseline dimensioning?
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.
How are dimensioning standards used?
they are used by showing where it is
3. What is the difference between chain dimensioning and datum dimensioning?
Chain dimensioning involves placing dimensions in a linear sequence, where each dimension is referenced from the previous one, which can lead to cumulative tolerances and potential inaccuracies. In contrast, datum dimensioning establishes a reference point or surface (datum) from which all other dimensions are measured, ensuring consistency and precision across the entire part. This method reduces the accumulation of tolerances and enhances the reliability of the dimensions. Overall, datum dimensioning is generally preferred for critical applications where accuracy is paramount.

What is contour dimensioning?
Contour dimensioning is a method of dimensioning a part by specifying the lengths of its contours or outlines. It provides an overall description of the part's shape and size without specifying the individual dimensions of every feature. This method is often used for parts with complex shapes where detailing every dimension would be impractical.
What does over- dimensioning mean?
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.
Which demensioning method permits the accumulation of errors and should be avoided?
The dimensioning method that permits the accumulation of errors and should be avoided is the "chain dimensioning" method. In this approach, dimensions are measured from a common baseline, leading to potential cumulative errors as each measurement relies on the previous one. Any inaccuracies in earlier dimensions can propagate through the entire assembly, resulting in significant discrepancies. Instead, "baseline dimensioning" or "coordinate dimensioning" methods, which minimize error propagation, are preferred for accuracy.
