2. The counterbore symbol is used on a drawing to indicate that a counterbore hole feature is required. Where an exception to this practice is necessary, the specific feature of the screw thread (such as MAJOR DIA or MINOR DIA) shall be stated beneath the feature control frame, or beneath or adjacent to the datum feature symbol, as applicable. To paraphrase the standard, the geometric tolerances and/or datum references apply to the pitch cylinder diameter unless otherwise specified. Our deigners use the decimal equivelant on all thread callouts; .500-13 UNC-2B. We will contact you if we have questions regarding your feedback. I don't like to change the leader attachment as this will de-link the parametrics. The first time you see a callout can be a little confusing, but its pretty straightforward once you know what the numbers are meant to stand for. There are decisions that machinists make every day that are not spelled out on any print. btb, I'm stymied on SWAG. The value listed with the symbol is the ratio of the diameter change to length change. If you change a hole dimension in the model, the callout updates automatically. Web Help Content Version: SOLIDWORKS 2021 SP05 . The two methods of using Position discussed on this page will be RFS or Regardless of Feature Size and under a material condition (Maximum Material Condition or Least Material Condition). 4 0 obj 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. The Independency Symbol is used on drawings to declare that the requirement for perfect form at MMC or LMC is removed and the form tolerance may be larger than the size tolerance. To report problems encountered with the Web help interface and search, contact your local support representative. WebThe tapped hole callout format is: tap drill diameter + depth; thread specification + depth; quantity of holes desired (not included if only one hole is specified) Notice that when working with blind threads (i.e. . Regardless of feature size simply means that whatever GD&T callout you make, is controlled independently of the size dimension of the part. Just make sure you also give the weights in imperial, to save confusion. For instance, you might see 2A and 2B screws, which are slightly different sizes. .
