Future Technology Used in Everyday Work

CAD models as holograms. Modifiable and collaboratively editable. Augmented Reality (AR) is expected to revolutionize workflows in factory planning. At BASF, the world’s largest chemical company, the use of AR already shows great potential.

The planning of a complete plant or even individual production lines has a significant influence on investment and operating costs. In addition, capacity utilization and the product quality itself are strongly dependent on good planning. However, virtual planning and reality still too often do not match. Data in the system becomes obsolete. Design faults make complex construction projects more difficult. Incorrect planning causes costs to skyrocket. 

Currently, working in the field is the focus of attention. So how can production environments be optimally planned? How can companies integrate new plants, machines and pipelines without stopping ongoing operations? And what will future workflows of engineers look like? The AR expert Holo-Light aims to take working with CAD models to a new level of collaboration and efficiency using augmented reality software. With its Augmented Reality Engineering Space (ARES), the company wants to close the gap between virtual planning and what is ultimately real. Teams of engineers at BASF have already integrated the new type of AR engineering into their daily work practice: Using ARES, they efficiently compare digital planning data with the real factory environment and document changes in real time on site.

From Paper to Augmented Reality

For more than 30 years now, engineers have been using 3D renderings of CAD models to check their manufacturability. Within the framework of classic workflows, they work in CAD systems such as AutoCAD: on 2D screens and on a reduced scale. The comparison with reality is then usually done manually. This means that engineers print out paper plans, draw in additional data from the CAD model and then – equipped with clipboards – check the designs in the field. This is a time-consuming and above all a error-prone process. For example, pipelines are incorrectly planned or not considered, power lines are not planned or ventilation ducts are only considered with rough positioning. The same applies to factory structures, already existing cable harnesses, machines and cells. Space requirements, connections or possible collisions are clear challenges in investment decisions. It can easily happen that a factory plant has to be subsequently adapted at great cost or even shut down temporarily.

Even at BASF, planning complex plants and pipelines without a real reference on a 2D screen often proved to be tricky. The chemical company needed a tool to visualize and edit components in the factories – i.e. on site – true to scale in the existing environment. It should also be possible to feed back the data for further planning. BASF now sees augmented reality as a key technology for the complete digitalization of factory planning and is actively promoting the use of AR in practice.

AR Workspace for Engineers

To be specific, BASF engineers use the Augmented Reality Engineering Space “AR 3S” of the AR company Holo-Light for the planning and expansion of intermediate product plants. In combination with Microsoft’s AR glasses HoloLens, the software suite offers experts a tool for visualizing, manipulating and collaboratively processing CAD data (e.g. from PLM systems) as holograms in a real environment.

With the help of AR 3S, engineers can retrieve planned pipelines and assemblies directly to their intended destination. Using the digital twin, it is thus possible to quickly determine whether planning and reality are compatible or whether changes are still required in the project. “What-if” test scenarios also give engineers a better understanding of their planned factory layout. And even during the engineering phase, on-site monitoring helps to detect and eliminate deviations early on before they lead to subsequent problems. This type of virtual planning is also a good basis for supporting and realizing maintenance and support processes via AR later on. For example, through additional step-by-step instructions or digital information that employees wearing AR glasses or mobile devices can call up at the appropriate location in the factory environment. 

Collaboration Made Easy

Factory planning has always been a discipline characterized by diverse influences from different departments. The interests of mechanical and plant engineering meet the interests of civil engineering and architecture. The Augmented Reality Engineering Space provides a collaborative environment to bring together different stakeholders. The software suite enables a very uncomplicated, fast and above all smooth experience of complex 3D models in a collaborative space. This means that all stakeholders can come together for a virtual engineering meeting regardless of location and work together on the CAD object. All the information noted in the working session or adjustments made to the digital 3D model can then be seamlessly integrated into the automation systems of subsequent workflows. This ensures cooperation across departments, divisions and plants.

A review in the form of an augmented reality meeting also has the additional advantage that inconsistent details, easily overlooked design errors or even necessary modifications to the model can be quickly identified or implemented by the specialist departments. Companies save their resources and make the planning process more efficient. It is also conceivable that factory planners and customers could jointly sketch, discuss and further develop designs or ideas in augmented reality. The customer can decide whether the production environment meets his requirements and the experts can plan and develop in a more targeted manner.

Get more from CAD

Basically, the AR working environment serves as a planning and collaboration platform. At BASF, for example, the AR software AR 3S in combination with Microsoft’s HoloLens makes planning more efficient and reduces construction errors. The visualization, manipulation and exchange of information are made easy by the intuitive handling. The appropriate augmented reality software is therefore not only a tool that generates advantages at the corporate level, but also supports engineers in their practical planning work by providing better, extended handling of CAD data.

And especially in times of social distancing, it is also an absolute advantage to rely on a collaboration tool that enables employees to continue working on important programs and projects. Without risk and even across large geographical distances. These advantages will not lose their effect even after the current virus crisis has been overcome. What acutely helps to further digitalize planning can in the long term create the basis for more efficient collaboration and optimize the entire engineering workflow.
