Dimension lines should be spaced uniformly throughout the drawing. They should be at **least 3/8″ from the object outline and 1/4” apart**. 13. No line of the drawing should be used as a dimension line or coincide with one.

The basic types of dimensioning are **linear, radial, angular, ordinate, and arc length**.
## What are typical dimension line terminators called?

**Arrowheads** are typical dimension line terminators. There are other acceptable dimension line terminators. Arrowheads point directly to the object that is being dimensioned or the extension lines at the end of the dimension.
## Which line is part of a dimension?

Arrowheads

Answer: Dimension lines are drawn using **continuous thin (narrow) lines (straight or curved)**. The given type of line in question is used to represent cutting planes. Explanation: The other lines are continuous thin (narrow) (straight or curved) which areused for grid, dimension.

## What is basic dimension in drawing?

## What is the standard for dimensions?

There are four main types of projection methods used in mechanical drawing in order to convey information such as **geometry, dimensions, tolerances, material and finish**.

3. Which is the wrong statement regarding dimensions? Explanation: **There is no such rule that the dimensions should be placed only on left side of drawing** because it may not possible to represent every dimension only on left side.

The dimension line is a fine, dark, solid line with **arrowheads on each end**. It indicates direction and extent of a dimension. In machine sketches and drawings, in which fractions and decimals are used for dimensions, the dimension line is usually broken near the middle to provide open space for the dimension numerals.

Symbol or abbreviation commonly found in a drawing are – “ diameter ” is represented by a symbol “ ”. – “ radius ” is represented by a letter “ R ”.

In a technical drawing, a basic dimension is **a theoretically exact dimension, given from a datum to a feature of interest**. … Allowable variations from the theoretically exact geometry are indicated by feature control, notes, and tolerances on other non-basic dimensions.

Dimensions are expressed as **width by length by height or depth in three-dimensional space**.

A hidden line, also known as a hidden object line is **a medium weight line**, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen. Sometimes they are used to make a drawing easier to understand.
## What is the purpose of dimensioning?

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.

## What is another name for parallel dimensioning?

## What is projection in design?

## What is meant by projection drawing?

## What angles do you use to draw an isometric drawing?

## What are the two systems of placing dimensions on a drawing?

## When dimensioning the circle the dimension line begins from the center of the circle?

**Continuous thin lines** are used for indicating dimension line, hatching line, revolved section, etc. Long chain lines are used to indicate center line, cutting lines.

Explanation: The dimensions are arranged in a parallel manner. Hence the answer is parallel dimension. This type of dimensioning is also called as **aligned dimension**, as the dimension figures are aligned along the length of the dimension line.

A 3D projection (or graphical projection) is a **design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface**. … 3D projections use the primary qualities of an object’s basic shape to create a map of points, that are then connected to one another to create a visual element.

The **process or technique of representing a three-dimensional object by projecting all its points by straight lines**, either parallel or converging to a picture plane.

What is isometric drawing? Isometric drawing is a form of 3D drawing, which is set out using **30-degree angles**. It is a type of axonometric drawing so the same scale is used for every axis, resulting in a non-distorted image.

Explanation: The two systems of placing dimensions are **aligned system and unidirectional system**. In the aligned system, the dimension is placed perpendicular to the dimension line.

Explanation: When dimensioning the circle, the dimension line begins from the centre of the circle. With the help of the leader line, the dimensions are written on it. The notations **φ** and R are used to indicate whether the dimension denotes diameter or the radius respectively. 4.
## When dimensioning a sketch to create a feature you should Mcq?

## What is the leader line?

When dimensioning a sketch to create a feature, you should:

**Place as many dimensions as possible on the sketch**. Place as many dimensions as possible on the sketch.

A leader line is **a line that establishes a connection between a graphical representation of an item and some text**. … A leader line also has a terminator and some text. A leader line may have a reference line under the text.

## How do you do the diameter symbol?

## What is basic dimension example?

The sizes of parts and overall sizes of assemblies are conveyed by dimensions placed on the drawing. The basic objective in dimensioning a drawing is **to give the manufacturing or construction personnel the dimensions they need to do their work without requiring them to add**, subtract, or estimate distances.

True Dimension-: True dimension is **the measurement, which is required after the machining**. This is the value that ought to be accomplished after the machining. ISO- Constraints-: When degrees of freedom of geometry have been taking up by a predictable combination of measurements and fixed geometry.

A dimension is **for size and position (of the designed/modeled shape)**. A DIMENSION is a numerical value expressed in appropriate units of measurement and used to define the size, location, orientation, form or other geometric characteristics of a part.

Basic Dimensions

The basic dimension **originates from the datum**. The basic dimension is enclosed by a rectangle. Basic dimensions are used to establish the “true profile” which a profile tolerance will then control. So if a profile tolerance is applied to a hole, the diameter MUST be a basic dimension.

The symbol or variable for diameter, **⌀**, is sometimes used in technical drawings or specifications as a prefix or suffix for a number (e.g. “⌀ 55 mm”, indicating that it represents diameter). For example, photographic filter thread sizes are often denoted in this way.

Basic Dimensions are typically used within the GD&T framework to control the location or geometry of features. The best example of when basic dimensions are used is **when specifying True Position**. Take a look at this drawing below: The basic dimensions are those dimensions in the boxes – the 30 and the 15.
## How are basic dimensions used?

## Do you measure basic dimensions?

Basic dimensions are **used to establish the “true profile” which a profile tolerance will then control**. … Geometric tolerances are a category of tolerances used to control size, form, profile, orientation, location, and runout. They are the preferred method for locating features of features of size on a part.

Based on the ASME standards, basic dimensions do not meet this definition of design characteristics – **they cannot be measured** and do not have requirements to conform to.
## How do you find dimensions?

## What are dimensions Lxwxh?

## What does dimensions mean in math?

## What is viewing plane line?

**Measure any two sides (length, width or height) of an object or surface** in order to get a two-dimensional measurement. For example, a rectangle that has a width of 3 feet and height of 4 feet is a two-dimensional measurement. The dimensions of the rectangle would then be stated as 3 ft. (width) x 4 ft.

The dimensions of this product are listed as **Length x Width x Height**.

dimension, in common parlance, **the measure of the size of an object**, such as a box, usually given as length, width, and height. In mathematics, the notion of dimension is an extension of the idea that a line is one-dimensional, a plane is two-dimensional, and space is three-dimensional.

viewing plane line. The **line used to define an auxiliary view**. If the line were projected through the drawing sheet to create a plane, this plane would define the view. The viewing plane line is displayed on the drawing sheet to show the orientation of the auxiliary view in relation to the principal view.
