Catalogue Database Elements Setup in PARAGON : 3D Geomset Primitives : Solid of Revolution (SREV)
Solid of Revolution (SREV)
This primitive is generated by rotating a user-defined 2D shape, known as a Loop (SLOO), whose outline is defined by a set of member elements called Vertices (SVER), through an angle about an axis. The swept angle must be in the range -360 to +360 degrees, 360 degrees giving a solid which is axially symmetrical.
In addition to the attributes defining its position, each SVER can have a radius which applies a convex or concave fillet to the loop at that point.
SREV has particular attributes as follows:
•
PX, PY, PZ - coordinates of origin of SLOO
•
PAAX, - directions of axes of SLOO
•
PBAX - (these will define coordinate system for SVERs)
•
PANGLE - angle through which 2D SLOO is rotated to form 3D SREV
SLOO has no special attributes.
SVER has particular attributes as follows:
•
PX, PY - coordinates of vertex
•
PRAD - fillet radius of loop at vertex position
