I ran across a drawing where the engineer had front, top and bottom views on the drawing but then next view to the side was the rear view. The justification was that the side view was "skipped". There was not really any room left on the sheet to put it above or below. I couldn't find anything...
I have a ball from a manufacturer with the following specs: Diameter - 0.500+/-.005" and "sphericity" - .005" Since the term sphericity is somewhat vague I wanted to get away from the notes describing the dimensions and show it with GD&T, however it seems that GD&T fails me here. The way I...
According to the standard this is a legal method of attaching FCF: 3.5 (d) "attaching a side, corner, or an end of the frame to an extension of the dimension line pertaining to a feature
of size" However, it just looks really weird to me.
I ran across this drawing where there were several views for two cylindrical parts and their assembly combined on a single sheet. The parts get pressed inside of each other and then a single hole is drilled through the assembly. What caught my attention was that each view was reusing the same...
One thing I'm still struggling to understand is what is the difference between specifying a single cylindrical feature datum for true position tolerance or the same with a flat perpendicular surface used as the secondary datum when no material boundary modifiers are used. Here is an example...
I have two slots and I want to control orientation of their center plane against the axis of the hole in the direction perpendicular to the plane of the front view (picture below)
The way I see it, if I use a true position tolerance I will be controlling location of the slot as well. The...
This came up on one of the drawings recently but I see it all the time, even in the textbooks. Say you have one circular feature with a perpendicularity constraint to a datum defined by a flat face and then you have another circular feature coaxial with the first one and having true position...
