Which type of line is never crossed by any other line when dimensioning an object?
Rigth line
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.
What is the importance of dimensioning?
To solve problems it is important that the dimensions of the answer are those that are input to the problem. In Engineering the dimensions of an item are important so that it withstands the loads it is subject to.
What is the tolerance representation in geometric dimensioning and tolerancing?
It is called postion and it is represented as a circle with a plus sign in it. For the symbol representations GOOGLE: Geometric Tolerancing Symols.

4 What types of numeric constraints may be applied to sketches?
Things like General Dimensioning and Auto Dimensioning
Which dimensioning method permits the accumulation of errors?
Tabular dimensioning
What are dimensioning standards?
Dimensioning standards are standards on how to dimension a working drawing.
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 types of numeric constraints may applied to sketches?
Things like General Dimensioning and Auto Dimensioning
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.

How are dimensioning standards used?
they are used by showing where it is
What does OA mean when relating to dimensioning?
18" o.a.
What is contour dimensioning?
Contour dimensioning is a method of dimensioning a part by specifying the lengths of its contours or outlines. It provides an overall description of the part's shape and size without specifying the individual dimensions of every feature. This method is often used for parts with complex shapes where detailing every dimension would be impractical.
