Enhance smaller features by depicting them in detail views

“

- [Instructor] When features are too small to be completely dimensioned in an orthographic view, a detail view acts like a magnifying glass, enlarging features so that they may be dimensioned in their own dedicated view. In this video, we'll show you how to present detail views in a drawing, as well as some special considerations for dimensioning so that features in detail views are properly located to the rest of the part. This O-ring groove has some intricate geometry that can't be easily dimensioned in this orthographic view. A detail view allows us to increase the scale for very small features, accommodating more annotations. Detail views can be taken from both orthographic and section views, or even other detail views. Details may be any shape, but circles are most common. Typically, the view identifier is enclosed by two arrows, but in cases where the letter would be hard to read, it can be connected with the leader. Auxiliary section and detail views are all identified with letters. They're assigned alphabetically, skipping I, O, Q, S, X, and Z, and a single lettering sequence is used for all views in a drawing. One challenge with detail views is locating the feature to the rest of the part. A good practice is to locate one of the surfaces in the parent view and then dimension from that surface within the detail. To summarize, use detail views when you need to dimension intricate features in their own view. Identify these views with letters just as you would with auxiliary and section views. And finally, be sure the features depicted in detail views are located in the parent view, with respect to the rest of the part.
