Alternatively, instead of translating from one CAD system to another, users can also go from CAD to a PDF file with Theorem Solutions’ 3D PDFs. 3D PDFs are a great way of sharing your data if you don’t want to invest in a licence for a partner’s CAD system, or if you’re working with people who don’t use a CAD system at all. Let’s clarify what we mean by 3D PDF – it’s


an interactive lightweight document format that displays a 3D model that can be manipulated, marked-up and annotated to aid communication and also make visualisation more effective. It supports Product Manufacturing Information (PMI), assembly structure, geometry, attribute

The most recent addition to Theorem Solutions’ product range is Extended Reality (XR) data preparation and experiences. This involves preparing CAD data for use in Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR). Theorem Solutions continues to adopt new


devices and formats to support the different sectors within the XR space. This includes support for AEC, Navisworks, Revit, IFC data which can be combined with CAD and scan data, and all loaded into a single environment. Theorem also provides the ability to work with and collaborate on huge data sets in the Microsoft HoloLens via Azure Remote Rendering.

information and metadata. 3D PDF is an effortless way to share rich engineering design data (e.g. 3DEXPERIENCE, CATIA V5, Creo, JT or NX) with non-CAD users. Being able to deliver a single interactive


document to anyone that needs to be involved in the design process without needing access to CAD (e.g. Procurement, R&D, Quality and Inspection departments) is a very powerful tool, which removes the need for physical documents and drawings to be shared. Using 3D PDF to share CAD data also helps to protect your IP, as native source files are never shared. One of the main benefits of 3D PDFs is that


they’re simple to share, and anyone can view them in Adobe Acrobat Reader which most people are already familiar with and have access to. As a result, most people are willing to use PDF documents, whereas they might be less willing to work with CAD data that they don’t understand. These 3D PDFs, when viewed with Adobe


Acrobat Reader, include a 3D model taken from CAD data, which can be manipulated as you usually would, i.e., pan, zoom, and rotate. Additionally, there are many other features for interacting with the model including hiding components and exploding geometry. Plus, you can password protect a document to ensure the security of your IP. Theorem Solutions’ 3D PDF documents allow


users a lot of flexibility. The layout of the document and the information it includes is fully configurable. Users can work with Theorem to create 3D PDFs that include all the information required e.g., assembly structure can be brought through from the native CAD. Plus, users can attach additional documents such as spreadsheets or 2D drawings, to ensure the information needed is all in one place.


NOVEMBER 2022 DESIGN SOLUTIONS 9 AR allows for the visualisation of CAD


data using a handheld device, such as a smartphone or tablet, digitally placing the model within your environment. AR makes XR adoption much easier. It uses familiar technologies that we know how to use. So, they are a perfect starting point for XR without costly new devices or hardware. Similarly, MR allows users to visualise CAD data within your environment; however, it is in the form of a full-scale 3D hologram using a headset like the Microsoft HoloLens 2. With VR users are immersed in a fully digital environment where they can visualise their CAD data at full scale and in context with a headset like the HTC Vive or Oculus Rift. Theorem-XR is CAD data and device


agnostic, taking most types of CAD data and


preparing and optimising it for almost any XR device. This data preparation can be for use in your own internal applications. Thanks to the support for Unity and Unreal development, in-house XR dev teams can quickly and easily prepare and optimise data without needing to spend time reworking design data when small changes are required. Alternatively, this data can be used in


Theorem’s experiences. These experiences include Visualisation, Design Review, Factory Layout, Visual Digital Twin, and Training. They are designed to be adaptable to a variety of use cases. For example, NCR uses Theorem’s Design Review experience to review digital prototypes with teams located around the world, saving £390,000 in their first year. Meanwhile Valiant TMS uses Theorem’s MR software to verify clearances and detect interferences at production plants by virtually overlaying digital models, reducing the time taken for some tasks from days down to a few hours with Theorem-XR. XR allows for collaboration between teams


who are remote or globally distributed which is common in the modern manufacturing process.


This cuts down on travel time, CO2 emissions, and costs where teams would otherwise have to meet in person to view a physical model. And since XR also provides the ability to visualise the data at full scale, it helps contextualise the model which can be difficult when just viewing it on a computer screen. Theorem Solutions’ engineering-focused


software solutions enable you to extend the use of your 3D design data. We offer specialist tools in the form of our three core services: CAD translation, interactive documentation with 3D PDF and full-scale immersive collaboration with Extended Reality. If you have a use case that could benefit from these services, our team is always on hand to discuss the possibilities.
