Facilities reconstruction gets accelerated thanks to automatic recognition of cylinders from big cloud of points.
Within CATIA Digitized Shape Preparation you can import Large Digitization Files After Large Digitized Cloud import, remain in CATIA Digitized Shape Preparation application to extract the cloud portion you need to work on. Switch to CATIA Digitized Shape To Surface application. You can now use Automatic 3D Primitive Recognition function which will recognize cylinders shapes within tolerances and parameters range required. After tuning the provided preview directly in 3D by excluding the unwanted shapes, expected Cylinders get generated as features., and remaining portions of the cloud that were not actually used are isolated too. Cylinders fine tuning remains of course possible: just edit them as usual CATIA Generative Shape Design features
