What is the difference between chain dimensioning and datum dimensioning?

What is the difference between chain dimensioning and datum dimensioning? … Chain dimensioning is when size dimensions of each object are listed such that the dimensions are lined up next to each other. Datum dimensioning is dimensioning in reference to a single point (datum = one piece of information).

Why is dimensioning important in technical drawing?

The purpose of dimensioning is to provide a clear and complete description of an object. A complete set of dimensions will permit only one interpretation needed to construct the part. Dimensioning should follow these guidelines. Accuracy: correct values must be given.

Where should dimension lines be placed?

Radial dimension lines should always be placed in the circular view of the arc, and should be drawn at an angle, never horizontal or vertical.
