NX 11 makes it easier than ever to leverage the power of a model-based definition (MBD) strategy in your company with the new Convert to PMI command. Convert to PMI rapidly transforms legacy 2D drawings into intelligent 3D models that help convey important information such as surface finishes and material specs to people who work in parallel product development processes.
PMI (Product & Manufacturing Information) helps achieve better quality control, while reducing rework associated with inaccurate or incomplete manufacturing information. It can even save companies as much as 40 full work days a year, which means you have more time for innovation in product design. After all, is that not why we do what we do?
Today I will show you how to convert a master model drawing to a 3D PMI object using the new Convert to PMI command in NX 11. If you have non-master model drawings, don’t fret. We’ll be covering how to convert those using the Convert to PMI command as well in a later NX Quick Tips tutorial.
Let’s first have a look at the model file (above). We can see that there are currently no PMI objects in the model file. Let’s also have a look at the drawing (below). As we move through the model navigator, each view is highlighted. Things are looking good, all of our views are selected, so we are ready to begin.
Go into the Drafting Tools tab and select the Convert to PMI command. The preview shows two dimensions that are not highlighted in red, so we will have to correct these errors to ensure all of the correct information is displayed. We see that the source of the error results from the selection types.
In the first object, a cylindrical face was selected, but the second object has the silhouette edge selected. To correct this, convert the selection of that object back to the edge of the housing face. Likewise, we see the same type of error to another dimensional selection. In both instances, the selected objects are silhouette edges and we want to change the selections to geometry faces instead.
Once this correction is done, as we go back and initiate the Convert to PMI command, we now see that both of those dimensions are highlighted to indicate that they will be included in the conversion. Now that we are ready, it’s time to execute the Convert to PMI command.
Hit OK to execute. It will take a few seconds to complete. Once that is done, navigate into the master model file to confirm that everything was included. The part navigator now shows the additional views that are generated from this process. Each one of these views contains the appropriate PMI objects that correspond to the original 2D drawings.
Let’s look now at the right view where we have all of our section planes properly defined, to review the result of those section views next. Everything seems to be in order, and the section views look good.
This type of workflow demonstrates how we could convert a 2D master model drawing into 3D PMI object. See the step-by-step process in action when you watch the video below!
