Reference Dimension Engineering Drawing вђ Nbkomputer A reference dimension is just what it sounds like. it is a dimension shown for reference. in other words it is there for informational purposes only. they are not a requirement in any way. reference dimensions can be used to clarify other dimensions on a drawing. in some instances, they make a drawing easier to understand. A reference dimension on a drawing should be identified by: a) ref b) typ c) parentheses d) an asterisk 10 mm what is the recommended minimum distance (x) that dimensions should be placed from a view?.
Engineering Drawing Reference Dimension вђ Otosection A reference dimension is a dimension on an engineering drawing provided for information only. [1] reference dimensions are provided for a variety of reasons and are often an accumulation of other dimensions that are defined elsewhere [2] (e.g. on the drawing or other related documentation). these dimensions may also be used for convenience to. The first dimension in a raw should be stuck to a base line. disadvantage of this system: it may result in an undesirable accumulation of tolerances between individual features. when several dimensions start from a common reference point or line, the method is referred to as common point, or parallel, dimensioning. Explanations for reference dimensions, basic dimensions, and inspection dimensions in gd&t are provided in this video. 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. they do have tolerances, though, as.
