In combination with 3D modeling, laser scanning has successfully been used within the automotive industry, amongst others, to evaluate materials and functionality prior to producing new models. MCAD uses laser scanning to create as-built 3D images for plants, machinery and buildings before reconstruction. These 3D images supplement the drawings with authentic representation of doors, tables and beams as well as existing equipment and all other interiors. The image consist of millions of measurable points, this point cloud of geometric samples can be used in several ways. E.g., by importing 3D images into the point cloud it’s possible to measure distances and determine placement of new machinery and piping. Various kinds of simulations can also be executed that detects collisions and clearances between existing and new installations.
