Reverse engineering (RE) is used in the manufacturing industry as a powerful approach to generate the digital twin of a physical object. Hereby, a data acquisition and model reconstruction methodology has been combined to resolve these issues. Such a data set often has to replace the missing original digital model. Subsequently, a model reconstruction plan has to be derived so that an editable CAD model which fulfils process requirements can be generated using standard geometry creation tools. Such a reversed engineered CAD model preferably contains form-feature based design intent and can be easily modified due to new design and manufacturing constraints. In some cases the scanned data are not complete due to the gaps in the acquisition procedure. To repair such meshes mobile low-cost scanner can be taken into account. In this paper the Microsoft HoloLens is used, a mixed reality headset. It scans the environment around and enables the user to place holograms on the real world and interact with it. To permit this experience, the HoloLens scans our environment and reconstructs a spatial mapping 3D mesh of it. So this device is used as in-door scenes 3D scanner to reconstruct a piping system. This approach is proven in reconstruction of piping systems.
