A common reference point for dimensioning is typically established by defining a datum feature on the part. This datum serves as the starting point for all other dimensions and measurements on the part, ensuring consistent and accurate referencing throughout the design and manufacturing process. Establishing a fixed reference point helps to maintain precision and consistency in measurements and alignments.

Why is it important to used fixed common reference point for dimensioning of drawings and sketches?
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.
What is a common frame of reference when you describe motion?
A common frame of reference when describing motion is the observer's point of view or a fixed point in the environment that is used as a reference to describe the motion of an object. This helps to establish direction, speed, and location of the object in relation to the observer or the fixed reference point.
What does reference point mean when having to do with speed?
A reference point in the context of speed is a fixed location from which the speed of an object is observed or measured. It provides a frame of reference for determining the speed of an object relative to that fixed point.
Why is it important to use fixed common reference point?
Using a fixed common reference point ensures consistency and accuracy in measurements or comparisons. It provides a stable and reliable anchor for making judgments or decisions, minimizing errors and confusion that may arise from using varying points of reference. This practice allows for better communication, understanding, and alignment among individuals or groups working with the same information.
What is a fixed point use to determine movement?
A fixed point is a reference point that remains constant during movement, allowing us to determine the direction and distance of the movement relative to that point. By using fixed points as landmarks or reference markers, we can navigate and track the changes in position accurately.

Why is it important to use a fixed common reference point for dimensioning of drawings and sketches?
It is important to use a fixed common reference point on your work peace or drawing to avoid cumulative error, i.e. if a hole is drilled using an incorrect measurement initially, then continuation to measure from the error instead of using a common reference point could result in a whole piece of work being scrapped. Also if somebody has to take over the work, they would need to understand were the dimensions were taken from to enable them to carry on with the work.

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.

How important the point reference?
Without a fixed Point of Reference, there is nothing to be relative to.

Why do we always start at the origin point?
It is because many things are measured with reference to a fixed point: it space or time. This point is called a reference point or origin.
