Depth Symbol 2.5 Dimension Origin - A circle used in place of one of the arrowheads on a dimension line indicates the origin for measurement. The difference is one group says also call out diameter of the hole to be The slope modifying symbol is placed with a value to indicate that this value is controlled as a slope, or a flat taper. The value listed with the symbol is the ratio of the height change to length change. Is it anything like TFB (that's fantastic boss)? Search 'Hole Callout Standards' in the SOLIDWORKS Knowledge Base. <> 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.". .

We often observe one measurement error using a best fit gauge pin to locate threaded holes when this procedure is not called out on the drawing. One of the few engineering jokes I think is funny, because I know it's true, how many times have we been there trying to debug a problem. ASR: Analyte Specific Reagents. 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.
