How to View CAD PMI

How to View CAD PMI

Product and Manufacturing Information (PMI) refers to metadata such as GD&T, dimensions and notes in the context of a 3D CAD model. PMI is a key component to MBD, or Model Based Design. It benefits design and engineering practices by tying the model metadata to the model itself, eliminating the need to maintain separate files for drawings, and making it easier to see where each dimension and tolerance note belongs. For more information on this, read Benefits of PMI and MBD. How to View CAD PMI Standard PMI Viewing Normally, all you have to do to view PMI is to open the model in TransMagic. System defaults should allow you to see PMI, if it exists. If you...
Missing CAD Data

Missing CAD Data

‘Missing CAD Data’ summarizes the many reasons you may not be able to find your CAD data. If you need more information on any of these areas, see the links and embedded videos at the end of each section. Empty Assemblies – CAD assemblies typically need parts in order to have any real CAD content. If your customer sends you a folder full of assembly files, and no part files, you probably have an empty assembly on your hands. Contact your customer and ask for the missing parts. Missing PMI – Sometimes there is no PMI (Product Manufacturing Information), sometimes the user just forgot to attach it, and sometimes it just needs to be turned...
Exporting PMI to 3D PDF

Exporting PMI to 3D PDF

Exporting PMI to 3D PDF Exporting PMI to 3D PDF is a simple matter of choosing the PMI views you want to export, and clicking the Export Views To File button. The ability to export CAD views, along with associated PMI, makes communicating with internal and external team members who may not have a CAD system, or even a CAD viewer. 3D PDF is a great equalizer since the free Acrobat PDF reader is already installed on the vast majority of computers. In the first figure, there is one view selected in the PMI View Browser (MBD_02). This view is the ‘front’ view, containing three GD&T elements. Only the PMI for the selected view is visible, allowing...
Benefits of PMI and MBD

Benefits of PMI and MBD

Product and Manufacturing Information (PMI) refers to metadata such as GD&T, dimensions and notes in the context of a 3D CAD model. Model Based Definition refers to the practice of using 3D CAD models, in association with PMI to define parts and assemblies without the need for drawings. In this article we will discuss some of the benefits of PMI and MBD. In future articles we will look at specific TransMagic tools for viewing and managing PMI. Benefits of PMI and MBD The ability to view metadata in the context of the part PMI allows you to clearly see GD&T, dimensions and notes in the context of the 3D model instead of in a separate drawing, making it...
Brep vs Visrep Models

Brep vs Visrep Models

What are the advantages of Brep vs Visrep models, and how do you tell them apart? Brep Models Brep refers to Boundary Representation. As the name suggests, the boundary between solid and non-solid geometry is in view here, the solid geometry being a collection of interconnected surfaces. This is a mathematically precise representation of geometry. Depending on the format and the CAD software you have in your possession, the features and underlying sketches may be editable, or the shapes may be editable – but generally speaking, if you don’t have the CAD system used to create the file, you cannot edit the features or sketches unless you run a...
CAD Format Analysis

CAD Format Analysis

What CAD format, and what version, did that colleague just give you? Most of the time it’s clear what format it is, and most of the time the version doesn’t matter, BUT – sometimes it does. This is a repost from a few years back. It has turned out to be one of our most referenced resources, so here it is again! The following CAD Format Analysis cheat-sheet will allow you to open up CAD files in a text editor like Notepad or Notepad ++ to find out what format they truly are, and in some cases, which version. I’ve seen cases from some of our customers where CAD files had, for whatever reason, been given the wrong extensions; once we learn...
