In the unidirectional dimension system, all dimension figures and notes are lettered horizontally and are read from the bottom of the drawing. The unidirectional dimension system is preferred over the aligned system because it is easier to read and understand.

Explain the difference between aligned and unidirectional dimensioning?

In aligned system you place the dimensions( or numerals) above the dimension lines so that they can be read from bottom or right edge of your sheet. In unidirectional system, all the numerals are placed along the dimension lines, all in the same direction such that they can be read from the bottom edge. This figure explains it clearly: http://www.maelabs.ucsd.edu/mae_guides/cad/dimensioning/Dimensioning_Fundementals_files/image034.gif

What is chain dimensioning?

It show dimension of given dig. Ex. length meter etc. > 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.
