Create_BoxOutline

Purpose

generate geometry outline for box section

Synopsis

[Outline,A,sy,sz] = Create_BoxOutline (Data)

Description

CREATE_BOXOUTLINE generate geometry outline for box section
  [OUTLINE,A,SY,SZ] = CREATE_BOXOUTLINE (NDM,DATA)
  the function creates the data structure OUTLINE for box section
  with geometric properties in data structure DATA with the following fields:
       ndm = 2 or 3 for uniaxial or biaxial section model, respectively 
       d   = total  depth
       bf  = flange width
       tf  = flange thickness
       tw  = web    thickness
       FlgOpt = true/false, FlgOpt = true : single outline for flange
       WebOpt = true/false, WebOpt = true : single outline for web
       FlgOpt = false + WebOpt = false : create separate outline for web-flange intersection 
     
  the function returns the following information
       A  = area of the cross section
       SY = centroidal distance relative to section mid-depth
       SZ = centroidal distance relative to section mid-width
