"Undet solved our point cloud extraction problem brilliantly. We needed a way to extract building geometry from point clouds so that we could design and dimension Energiesprong type retrofit panels. The process had to be fast, easy to use, easy to learn, precise and reliable. Undet does it all. The plane and corner extraction tools give us the basic building outline quickly with the accuracy we need (+/- 6mm)- even with a non-survey grade scanner. Two other features combine to make locating the building details fast, reliable and accurate. The first is the ability to increase the visible point cloud density as you shrink the clipping box. The second is the ability to colour the points according to the distance from the clipping plain. Genius!"
