Snout (LSNO)

The Snout primitive is a cylindrical element of varying diameter along its length. It may be eccentric or concentric. LSNO has particular attributes as follows:

• PAAX—direction of axis normal to top surface of snout (the A axis).

• PBAX—offset direction.

• PTDI, PBDI—distance along A axis to top, bottom surfaces of snout.

• PTDM, PBDM—diameter of top, bottom surfaces of snout.

• POFF—the offset/eccentricity of the snout as measured in the PBAX direction.

• TVISI—visibility of top face.

• BVISI—visibility of bottom face.

The sizes of the top and bottom surfaces of the snout may be defined in terms of their radii instead of their diameters.

• PTRA, PBRA - radius of top, bottom surfaces of snout
