Structural Profile (SPRO)

This element represents a user-defined 2D shape whose outline is defined by a set of member elements called Structural Profile Vertices (SPVE). The lines joining adjacent SPVEs form the edges of the SPRO.

In addition to the attributes defining its position, each SPVE can have a radius which applies a convex or concave fillet to the profile at that point.

SPRO has particular attributes as follows:

• PLAXI - direction of Y axis of profile (this defines coordinate system for SPVEs)

SPVE has particular attributes as follows:

• PX, PY - coordinates of vertex

• DX, DY - offset of coordinates between start and end of a tapered section

• PRAD - fillet radius of profile at vertex position

• DRAD - change of fillet radius of profile at vertex position between ends of section.
