In past Metrology Minute articles, we discussed the ability to import PMI data into Control X using the File, Import PMI option. As a reminder, PMI (Product Manufacturing Information) allows dissimilar systems to share manufacturing information specifically related to dimensioning and tolerances. So, for example, a Solidworks user can add PMI to their Solidworks model (see example below) using the MBD tab and then that PMI information, including but not limited to; Datums, dimensions with tolerances, GD&T, notes, labels, etc. may be transferred with the model into programs like Control X, to be used for inspection calculations.
But what if a Solidworks user wants to provide a PMI model to a supplier but doesn’t necessarily want to provide their native SW model? Historically there have been two Step formats; Step 203 and Step 214. A few years ago, a new Step format was introduced called Step 242 which is basically a Step file that also includes PMI information. This means that along with the Import PMI capabilities in Control X whereby the CAD model and associated PMI values are all imported, Control X now also provides a Step 242 Import capability. Most CAD systems that can create PMI information to be added to a 3D model can also export or “Publish” a Step 242 file.
Below we show the menu options both for importing PMI models into Control X as well as for importing Step 242 models.
