Module 5.0 - Cyclone Basic Modelling
Introduction
The modelling process in Cyclone, in general, involves creating best fit geometric objects to the
point clouds. Cyclone has several types of object fitting functions for the user to choose from
depending on the topology of the scanned point clouds.
Objectives
The objective of this module is to introduce you to a general workflow for modelling point
clouds. You will model a plane, cylinder, elbow, box and steel shape. In modelling objects in the
registered QuickStart database, you will also learn techniques that can be utilized to easily select
sub-selections of point clouds from the whole of registered scans. You will also see some
methods that can be used to further edit the fit objects, such as extend, extrude, and handle
manipulation.
