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.

Why do engineers generally adhere to a set of dimensioning standards and guidelines?
Engineers adhere to dimensioning standards and guidelines to ensure clear communication and consistency in technical drawings and designs. These standards help prevent misunderstandings, reduce errors, and facilitate collaboration among diverse teams and stakeholders. By following established conventions, engineers can also ensure compatibility with manufacturing processes and quality control measures, ultimately improving product reliability and safety.

How does a chain hoist work?
A chain hoist uses gears to multiply force.A chain hoist is operated by hand. An operator pulls the light loop chain on the side of the chain hoist. This turns a gear mechanism inside the chain hoist housing to turn the chain pulley. When this pulley turns, it raises the heavy chain which usually has a hook on the end. By pulling the light chain loop, the manual hoist is actually able to increase the force that is being applied by the heavy chain. This is caused by the gear ratios inside the manual chain hoist. The mechanical work done by the operator is the same as the work done by the heavy lifting chain.

What is the difference between datum dimensioning and chain dimensioning?
Datum dimensioning is where a single reference point is used for all dimensions in a single direction. E.g. If Point A is declared the reference point, then Points B, C, D, etc, will all be measured relative to Point A, not to each other. Chain dimensioning is where each point is measured to the next. E.g. Point B is measured from Point A, Point C is measured from Point B, Point C is measured from Point B, and so on. The problem with chain dimensioning is that each measurement relies on the accuracy of the previous measurement. If there is a tolerance associated with each measurement (+/- X), then the tolerance for each subsequent dimension accumulates and becomes the number of measurements times the tolerance of each measurement (+/- n*X). Since datum dimensioning uses only one reference point, the tolerances cannot accumulate as each measurement is isolated, rather than relying on the accuracy of the previous measurement. Common practice is to only use datum dimensioning in design drawings to ensure greater accuracy over the entire design without requiring tighter tolerances.

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

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.
