Reference dimensions on true position. by crystal bemis on june 17, 2024. in this question line video, jason answers the following question regarding reference dimensions on true position: if a diameter is reference () on the drawing, does that make the gd&t under the diameter callout reference as well? to answer this question, jason walks. 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. The symbol for a basic dimension is the dimension shown enclosed in a rectangular frame or box. this is the convention identified in the blueprint drawing standard asme y14.5. some drawings may list a basic dimension not in a rectangular frame but instead the dimension will be followed by a bsc. notation.
