To report problems encountered with the Web help interface and search, contact your local support representative. Projected tolerance zone symbol In the case of a tolerance of orientation (angularity) and position, the tolerance can also apply to the external projection of it and NOT to the tolerance itself, hence this is a projected tolerance zone.

The best example of the use of projected tolerance zone would be a pattern of BLIND threaded holes where threaded studs would be assembled. The pointer must be in a Tolerance or Primary, Secondary, or Tertiary box to insert a material condition.  © 1995-2021 Dassault Systèmes. The threaded studs assemble through a pattern of holes of a mating part that, let's say, on .75 inches thick material. The Projected Tolerance Zone modifier is the letter P in the circle in the feature control frame. material condition modifiers based on the selected geometric 233. An error occurs when it • Mainly position and perpendicularity. The "main" dimension you talk about is the nominal dimension, so people do believe the nominal is the middle number of the tolerance zone, but that's not what nominal means. Click Geometric Tolerance (MBD Dimension toolbar) or Tools > MBD Dimension > Geometric Tolerance. To set geometric tolerance properties, do one of the following: Select a material condition. the upper tier is “A,” but “B” is entered as primary in the lower tier. Step 4: Allow Dynamic Interaction of Tolerance Zones between Features in a Part, and across parts, simulating Assembly possibilities for Maximizing Tolerances. Positional tolerances of threaded holes and through-holes for fixed fasteners (Figs 6.10 and 7.1) are usually calculated from the maximum diameter of the bolt and the minimum diameter of the through-hole (see 6.7). It is no longer inside the part. We have detected you are using a browser version older than Internet Explorer 7. The application of this concept is recommended where the variation in perpendicularity of threaded or press-fit holes could cause fastener, such as screws, studs, or pins, to interfere with mating parts. The projected portion of the stud will secure another mating plate. An error occurs for nonconforming datum sets, for example, if the primary and secondary datums are two parallel planes. The specified tolerance applies only to the projection of the hole indicated by the projected tolerance. Use the Frames box to move among frames. Any alternative If you’re familiar with the different GD&T modifiers, then you probably know that the circled P creates a “projected tolerance zone.” This is often used on threaded holes to keep any fastener that protrudes beyond the threaded hole from causing interference with a mating part: You can apply flatness and straightness tolerances on a unit basis. •Tangent Plane An error occurs when the feature is not a All rights reserved.
