Sincerely,The SOLIDWORKS Documentation Team. Jbeckhou -- I don't know if it's been mentioned above as to what standard your drawings are using (and there should indeed be a note imposing a standard) but the ASME standard Y14.5 clearly states in paragraph 1.4(e) that "the drawing should define a part without specifying manufacturing methods.". The Projected Tolerance Symbol is in used GD&T to indicate the tolerance zone of a feature is to be assessed beyond the surface extents of the feature. There is something called an "entity" in the reference type when placing a control frame, pick the type of G_TOL that you want, the ref type changes depending on which control tolerance you pick, then see if you can attach it to a call-out using one of the references that it gives you, maybe entity will work, if its available. Unified national extra fine. The Arc Length symbol, also known as the Arc Modifying symbol, is placed above a value to indicate that the arcs length is being dimensioned on a curved outline.

There are a couple of different labeling systems throughout the world, so keep in However, this procedure engages the thread minor diameter, not the pitch cylinder, and it is only permitted when the note MINOR DIA is added below the feature control frame. The basic callout system is meant for machine screws. Designed for the clinical laboratory the Navios EX delivers proven reliability and performance with improved sample traceability and reporting functions. Regardless of feature size simply means that whatever GD&T callout you make, is controlled independently of the size dimension of the part. .

Due to the specialized gauges required to locate threads from the pitch cylinder, it is good practice for engineers and designers to use the MINOR DIA note for internal threads and the MAJOR DIA note for external threads where possible. It means the external threads are 12mm (0.47in) wide. For instance, on a M12 x 1.75 x 85 callout, M12 is the diameter.
