============== Begin Application Remarks ====================
Numerical evaluation of the geometric properties of a line
from x=2 to x=6 so length is 4, cg is 4, inertia is 69.33
Nodal dof: none (geometry study only)
Element type = 1 (a parametric line)
Element connection: two nodes per element
Element properties: none (later add areas)
NOTE: nodal BC_Flag not used here, enter zero for it
=============== End Application Remarks =======================
