He discusses that + or DRAFT is a tool given by this standard that can be added to a size dimension to identify the draft allowed for easier removal of a casting from a mold. He then walks through two examples given in the standard and explains how to handle (and where to find) the tolerances for the draft features.

"What is GD&T A Simple Explanation We know that many of you are trying to figure out how GD&T works on a drawing. This is a video from our course where we explain how GD&T can be used to apply a refinement tolerance onto a simple part - your own bathroom mirror. GD&T is used to refine specific functional requirements to be absolutely clear and also allows you to loosen other requirements on the drawing that may be less important.

"Profile Unequal Zone In this Question Line video Jason discusses the ISO Unequal Zone (UZ) modifier which is similar to the Unequally Disposed modifier of the ASME standard. He walks through the feature control frame in an example drawing to explain what the tolerance zone would look like defining the total tolerance zone size and the amount and direction of shift in tolerance.

"Positional Control of XY and Z In this Question Line video Jason discusses the positional control of the X Y and Z translations for a cylindrical post on the submitted drawing. He defines the datum reference frame and zero point of the part and explains why the feature control frame in question is essential to constraining where the cylinder exists vertically.

"Profile of a Surface vs Profile of a Line In this Question Line video Jason discusses the difference between Profile of a Surface and Profile of a Line. He walks through two examples to show that the design difference between Profile of a Line and Profile of a Surface depends on if and which datums are referenced in the feature control frame.

"Effects of Larger Tolerance Values In this Question Line video Jason discusses a drawing that has a tight tolerance on the location of two holes that relate back to datum features that have much larger form control tolerances. He answers the question of whether this will affect measurement repeatability explaining the difference between datums and datum features and how measurements are taken. He also looks into how the tolerance of the datum features affect the minimum wall thickness of this part. Interested in learning more about Print Reading or GD&T Check out more of our free GD&T"

"Importance of Qualifying Datums In this Question Line video Jason discusses how to interpret a submitted drawing and inspect the manufactured part. He discusses the difference between how CMMs and physical datum simulators set up the datum reference frame for the manufactured part and demonstrates why physical datum simulators are best at establishing the correct zero point (000). He also explains how the datums for this part would be qualified and that the combination of datum simulation and datum qualification will solve the ambiguity coming across in this drawing.

"How to Find Zero In this video Jason shows how to find the zero or origin for a given feature control frame. He walks through an example drawing that utilizes a single datum reference frame describing how the datum reference frame fully constrains the part. He also notes that more complex parts may utilize multiple datum reference frames resulting in multiple origin points.
