WebJun 21, 2024 · The profile of a line tolerance is a 2D GD&T callout that can define and control a linear/curved feature or a surface cross-section within specified limits. We can use it to control the form, location, orientation and size of a feature. This callout can only be used on surfaces and cannot be used to locate a central axis or plane. http://www.engineeringessentials.com/gdt/straightness/straightness-surf.htm

WebIn GD&T, total runout is a complex tolerance that controls a feature ‘s straightness, profile, angularity, and other geometric variation. Total runout is different than runout because it applies to an entire surface simultaneously instead of individual circular elements. An example of total runout tolerance is shown below. WebStraightness is a condition where one line element of a surface or an axis must lie in a straight line. It controls how much a feature of one line element of a surface can deviate from a straight line. Straightness tolerance is …
