Cylinders get 3D position:
• from the cylinder intersection algorithm when the cylinder is referenced on two or more oriented photos
- fires when a cylinder has marks referenced/unreferenced
- fires when a cylinder point is moved
- fires when one of the photos its mark appears on is oriented, reoriented or forced unoriented
- fires when the user changes camera parameters or camera station parameters for that photo
- fires after global optimization
Note that there are special requirements for photography to properly create cylinders. See the Quick Start Guide section Photography for Curves, Edges and Cylinders.
