Straightness can apply to either a flat feature such as the surface of a block, or it can apply to the surface of a cylinder along the axial direction. The standard form of straightness is a 2-Dimensional tolerance that is used to ensure that a part is uniform across a surface or feature.

The cut feature must contain a circular sketch: You can add tolerances and precision to hole callouts: You can add hole callouts in standard drawing views and in section views. To help decipher the number ratings, look up a conversion chart online. The Radius symbol is used when a circular feature is dimensioned using the radius length. A female is threaded on the inside, like you would find on the inside of a nut or the socket for a light bulb. I've written about this before as well: http://www.fcsuper.com/swblog/?p=91

A #4-40 UNC-3A x .5 screw is 0.5in (1.3cm) long. If you see a callout like #4-40 UNC-3A x .5, the UNC tells you that you have a coarse screw. 2. use show dim to place the GTOL outside of the drawing border to have easy access to modify it. The system the callout uses is very important since similar screws can be different sizes. Last Updated: January 5, 2020 In most cases that I know of you need a dimension, a surface or an edge to attach a G_TOL control frame. The ASME Y14.5 Standard, section 2.9 Screw Threads states, Each tolerance of orientation or position and datum reference specified for a screw thread applies to the axis of the thread derived from the pitch cylinder. A scheduled system update will be performed from 6 PM to 9 PM PST Saturday, March 4th. 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. Create the hole note as a separate note and remove &METRIC_SIZE from the note. Context helps avoid errors, such as knowing that the screw came from a non-American car.

The diameter symbol is used to indicate that the size of a circular feature is being dimensioned using the diameter of that feature. If you select a face, hole tables do not include advanced holes. The unequally disposed profile tolerance symbol is used to apply unilateral or unequal tolerance zones to a profile of a part. You can create hole callouts for holes created with the Advanced Hole tool. Each of them is composed of several (variable) segments, coding for about 90 amino acids, very short D(diversity) segments (alpha and delta loci only), and short J (joining) segments (about 15 amino acids), and one or two C (constant) segments. 40 machinists who cannot tell good thread from bad thread and have to be baby-sitted.
