Abstract: A method, computer program, and device for testing the installation or removal of at least one component within an installation environment, comprising real and virtual elements. A component, installation environment, installer's hand, and a mixed reality system worn by the installer may be calibrated. During an installation or removal attempt, the component, installer's hand, and mixed reality system are tracked. Collisions or near-collisions between the component, installer's hand, tool, and the real and virtual elements, as well as among components, are detected. Obstructions are identified. The installation or removal attempt is visualized via the mixed reality system. Additionally, the installation or removal path and information on collisions or near-collisions are displayed.

Abstract: A measuring device for aligning a blueprint coordinate system with a build level coordinate system of a working region of a generative manufacturing device arranged in a build level includes a first sensor device configured to cover a first coverage region of the working region with a first measurement accuracy, a selection module configured to select at least one region of interest within the first coverage region, a second sensor device configured to cover the at least one selected region of interest with a second measurement accuracy, the second measurement accuracy being higher than the first measurement accuracy, and an alignment module configured to determine at least one alignment of the blueprint coordinate system relative to the build level coordinate system, including an angle alignment and/or a translation alignment, based on the covered region of interest.
