- The general guideline is that each dimension should be placed on the view which shows the dimensioned feature most clearly, and which gives the clearest and least cluttered drawing. On a multiview drawing, dimensions should generally be placed between adjacent views.

Dimensioning a drawing also identifies the tolerance(or accuracy) required for each dimension. 1. Dimension — the numerical value that defines the size, shape, location, surface texture, or geometric characteristic of a feature. 2. Basic dimension — a numerical value defining the theoretically exact size, location, or orientation relative to a coor...
To avoid having many dimensions extending away from the part, arrowless dimensioning may be used. 1. the “zero” lines represent the vertical and horizontal datum lines, 2. each of the dimensions shown without arrowheads indicates the distance from the zero line. 1. There shall never be more than one zero line in each direction. 2. Arrowless dimensi...
In standard practice, dimensions are grouped on a drawing for uniform appearance. Avoid using object lines as extension lines for a dimension. Dimensions must be kept outside the boundaries of views, wherever practical. Dimensions can be placed in series and parallel. 1. When a series of dimensions is applied on a point-to-point basis, it is referr...
The general practice is to stagger the dimension text on several parallel dimensions. 1. Horizontal — the left-to-right distance relative to the drawing sheet. Here the width is the only horizontal size dimension. 2. Vertical — the up and down distance relative to the drawing sheet. Here the height and the depth are both vertical dimensions, even t...
The dimensions can be classified by type of location or orientation: 1. Horizontal position – locates the position of the feature in horizontal direction with respect to a base; 2. Vertical position – locates the position of the feature in vertical direction with respect to a base; 3. Angle – gives the angle between the horizontal plane and the slo...
Angular dimensions are shown either in decimal degrees or in degrees, minutes, and seconds.Where only minutes and seconds are specified, the number of minutes or seconds are preceded by the 00.Holesare typically dimensioned in a view which best describes the shape of the hole. Diameters must be dimensioned with the diameter symbol preceding the numerical value. When holes are dimensioned...
Repetitive features and dimensions may be specified by the use of an “X” in conjunction with the numeral to indicate the “number of times” or “places” they are required. A full space is left betwee...
Aug 1, 2024 · Place Dimensions Outside the View: Whenever possible, place dimensions outside the view of the object being dimensioned. This helps to keep the view uncluttered and makes it easier to identify the features being dimensioned.
Dimensions should not be placed on a view unless clarity is promoted and long _____ lines are avoided. Adjacent Dimensions applying to two ______ views should be placed between views, unless clarity is promoted by placing some of them outside.
Dimensions should be placed between views, unless clearness is promoted by placing some outside. Dimensions should be attached to the view where the shape is shown best. Do not dimension hidden lines.
It is important to remember to place dimensions on the views, in a two or three view drawing, where they will be the most easily understood. Avoid dimensioning to a hidden line and avoid the duplication of dimensions. Use common sense; keep dimensions as clear and simple as possible.
When it comes to dimensioning, there are certain principles to be remembered. Firstly, every feature of the object should have a dimension. Redundant dimensions should be avoided, and the dimension should be attached to a view where the shape description is most apparent. Where possible, avoid dimensioning to hidden lines.
