WebJul 8, 2024 · The example listed shows a straightness callout of .005" per 1.000" and the composite tolerance of .020" on part with a length of 4.00". Since the part just happens to be 4", their contention is that the .020" tolerance is calculated by multiplying the tolerance per inch by the length divided by per units measure (inches in this case). WebGD&T Flatness is a common symbol that references how flat a surface is regardless of any other datum’s or features. It comes in useful if a feature is to be defined on a drawing that needs to be uniformly flat without tightening any other dimensions on the drawing. The flatness tolerance references two parallel planes (parallel to the surface ...

Flatness Symbol Flatness … WebFlatness is often described as being “the 2D version of straightness”. A straightness requirement applies to a 1D (linear) surface trace or axis in 3D space, whereas a flatness requirement applies to a 2D (planar) surface in 3D space. A flatness measurement can be approximated by a series of straightness line-measurements but note that the ...

WebIt looks as though you're getting confused with the GD&T symbols. I think the question is to ADD the flatness and parallelism call outs (flatness looks like a rhombus, & parallelism: //).
