Perpendicularitymeans flatness at 90 degrees to a datum. It specifies two perfect planes the feature plane must lie in between. Parallelismmeans straightness at a distance. Parallelism for axes can be defined by defining a cylindrical tolerance zone by placing a diameter symbol in front of the tol...
GD&T ensures that everyone involved in technical drawings – from design to machining – speaks the same language. Their vocabulary consists of geometric characteristics, such asflatness, straightness, cylindricity, roundness, perpendicularity, parallelism, angularity, position, profile, concentricity, and ...

byGD&T Basicson February 14, 2021. This video is in response to a question that we received on our question line from Jamee. Jamee’s question is as follows: “For parallelism of a circular feature of size (axis) can you use two... ...
Parallelism is a fairly common symbol that describes a parallel orientation of one referenced feature to a datum surface or line... Learn Symbol → Circularity The circularity symbol is used to describe how close an object should be to a true circle... Learn Symbol → Straightness The...
Parallelismis a refined form of angularity. Here, the datum is the surface we need to imitate and the angle is set to 0°. There are 2 types of parallelism: surface parallelism and axis parallelism. We can choose an axis or a surface as a reference. This becomes our datum and we refer...
Parallelismmeans straightness at a distance. Parallelism for axes can be defined by defining a cylindrical tolerance zone by placing a diameter symbol in front of the tolerance value. Location controlsdefine feature locations using linear dimensions: ...
Symbolized by two oblique parallel lines, parallelism is the condition of a surface or feature’s center plane, equidistant at all points from a datum plane; or a feature’s axis, equidistant along its length from one or more datum planes or datum axis. Angularity Symbolized by two lines at...
