To a certain extent, it is arbitrary. The designer chooses based on: -practicality of measuring from datums or origins -critical faces, surfaces, or dimensions -application. Sometimes, datums for a part are kept the same as the ones chosen for the overall assembly, especially if the design is a collaborative effort.
The location of the origin or datum for all the edges and features of an object is arbitrary. The designer chooses the origin based on practicality, critical faces, or application.
for my ideal, these software are web browser and serch engine
The first home computers could do anything any other computer could, if you could fit it in their tiny memories.However the first electronic computers in the 1940s and 1950s had exactly the same problem, very tiny memories.

Lines that extend off the object to show what is being dimensioned
no
The similarity between communicating about an object or product through a dimensioned drawing and a written description is that they are both used to describe it, and they can both be descriptive. The main difference is that a drawing is able to show a picture of it.

The centre of gravity does not, by itself, determine whether an object is at rest or in motion. The location of the centre of gravity, relative to where the object is supported, can contribute one of many forces that can act on the object. And it is is the [vector] sum of these forces which determines whether the object remains at rest or in uniform motion.
The density of the object or the shape of the object (like a boat) determines the buoyant force.
when there is a pull of an object towards the grand
An object's absolute location is its objective location, which technically doesn't exist. Relative location is the location of one object in relation to another object.
the density of the object that gravity is working upon determines it.
The location of an object is its position.
