A dimension that exactly locates a reference point, reference line, or reference plane
A dimension is a measurable extent of some kind, such as length, breadth, depth, or height.
2d shape is a dimension
The definition to an Extension Line is:A line used to visually connect the ends of a dimension line to the relevant feature on the part.How Extension Lines are used:Extension lines are solid and are drawn perpendicular to the dimension line.- DarKeneD
The datum supporting my argument comes from my experiment outlined in my report.
Datum is latin for "That which is a given, that which is taken for granted." Its plural is the more common "Data."
We have to make some choices when we dimension a block with a notch or cutout. It is usually best to dimension from a common line or surface. This can be called the datum line of surface. This eliminates the addition of measurement or machining inaccuracies that would come from "chain" or "series" dimensioning.
a theoretically exact point, axis, or plane derived from the true geometric counterpart of a specified datum feature. A datum is the origin from which the location or geometric characteristics of features of a part are established.

No, then it would not be a reference dimension. Reference dimensions by definition have no tolerance.
2d shape is a dimension
Datum is not the plural of data. Datum is singular, and its plural form is data.
Correction: What is hydrographic datum? not "hydrography"
The meaning of linear dimension is to measure in a straight line with the units. Which are Kilometer, Meter, decimeter, centimeter and lastly millimeter.
datum is the plane in which we can sketch any thing thing
sorry but i don't think there is something as datum
Datum is singular. Data or datums is plural.
A dimension is a measurable extent of a particular aspect, such as length, width, height, or time, that helps define the size, shape, or position of an object or space.
