MBE PMI Validation and Conformance Testing Project
Test Case PMI Annotation Browser
Before using the test case browser below you should be familiar with the test cases in the MBE PMI Validation and Conformance Testing Project. Thumbnails of each Test Case are shown below with links to 2D drawings. The browser lets you explore in detail the distribution of PMI annotations in the test cases. For example, you can find the test case with the only line profile tolerance (CTC 2) or the only parallelism tolerances (FTC 8) or with basic dimensions (CTC 4 and 5) or without any surface or position tolerances (CTC 5).
- A browser for the verification testing results is also available.

The browser uses the open-source version of Keshif, a web-based data exploration environment for data analytics. There are three frames in the browser below:
- Test Cases (five CTC and six FTC) contain 421 PMI Annotations. FTC 7, 10, and 11 were not modeled in any CAD system as part of the project.
- Annotation Type classifies PMI Annotation by dimensions, geometric tolerances, datum features, and datum targets. Dimensions are split into three categories including dimensions related to holes (counterbore, countersink, depth) and other dimensions (radius, slope, taper, slot).
- PMI Annotations with multi-line feature control frames (FCF) are displayed on one line. A "|" delimits the sections of a FCF. A "/" delimits mulitple lines of a FCF. Tolerance zone and datum reference frame modifiers such as a maximum material modifier (letter M in a circle) appear as the letter bracketed by parentheses, e.g., (M). Tolerances or dimensions with “(Oriented)” after the FCF means that the tolerance or dimension has a specific orientation in a test case drawing. Other modifiers similar modifiers are: Origin, All Around, and UOS. UOS means “Unless Otherwise Specified” and is usually associated with an overall surface profile in the notes.
Mousing over a text label (e.g. FTC 6 or Position or C1) highlights the bar in orange and associated data in the other frames showing the relationships between the data. Clicking on the text label filters information in all frames by the selected value. Clicking on a selected value deselects it. After one text label has been selected, more can be selected by clicking 'Or' to the left of a label. Data can be filtered out by clicking 'Not' to the left of a label. PMI Annotations can also be filtered with a Search string.
