Question: What Are The Rules Of Dimensioning Drawing?

What are the do’s and don’ts of dimensioning?

Dimensioning Rules Avoid placing any dimensions on the part (inside the view) unless there is no other option.

Avoid dimensioning to hidden features Always place the dimension where the characteristic shape is shown in the most descriptive view.

(This means don’t place a dimension on object lines making a “T joint”.).

What is short break line?

Short break lines are thick, wavy solid lines that are drawn freehand. When either of these break lines is used to shorten an object, you can assume that the section removed from the part is identical to the portions shown on either side of the break.

What is meant by dimensioning?

Dimensioning is the process of measuring either the area or the volume that an object occupies. It is the method of calculating capacity for the storage, handling, transporting and invoicing of goods.

What is the heaviest line in a drawing?

The heaviest line weight indicates the ground line cut. The next heaviest line weight “profiles the planes closest to the plane of projection” (Ching & Juroszek, 1998, p. 152). Medium line weight indicates distance from picture plane, progressively getting lighter to describe objects further from the picture plane.

What are the two basic types of dimensions?

There are two classifications of dimensions: size and location.Size dimensions are placed in direct relationship to a feature to identify the specific size.Location dimensions are used to identify the relationship of a feature to another feature within an object.

Why are dimensions important in 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.

What are different types of dimensions?

Can dimension lines cross?

Dimension lines should not cross, if avoidable. Dimension lines and extension lines should not cross, if avoidable. Extension lines may cross each other. When extension lines cross extension lines or visible lines, no break in either should be made.

What are the rules of dimensioning?

Overall dimensions should be placed the greatest distance away from the object so that intermediate dimensions can nest closer to the object to avoid crossing extension lines. 9. A dimension should be attached to only one view (i.e., extension lines should not connect two views).

What are dimensioning tools?

The Dimensioning tab contains tools that are useful for creating objects which must fit predefined dimensions or for dimensioning objects you have created. These tools can also be accessed via the Tools > Dimensioning menu. They can be used to dimension a line, edge, bounding box, angle, and radius/diameter.

What are the 7 types of lines?

There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc. and are often very expressive.

What are 5 types of lines?

There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines. Other types of lines are simply variations of the five main ones.

What are dimensioning tools in AutoCAD?

AutoCAD’s dimensioning tools can automatically measure distances and place dimensions on your drawing. You can simply select objects and let AutoCAD add the appropriate dimensions, or you can tell AutoCAD what type of dimension you want to place and what object or points you wish to dimension.

What are dimension styles in AutoCAD?

A dimension style is a named collection of dimension settings that controls the appearance of dimensions, such as arrowhead style, text location, and lateral tolerances. You create dimension styles to specify the format of dimensions quickly, and to ensure that dimensions conform to industry or project standards.
