Created SPC Section

• SPC Section List : Indicates the cross section list for calculating cross section properties.

• Preview : Shows a preview of the calculated cross section.

• Add :
  Opens a window for calculating section properties.
  (Before opening the window, the ‘Break object for calculating section properties’ operation is performed.)

• Modify : Modifies the results of section property calculations.

• Delete : Delete the cross section whose properties were calculated from the list.

• [Command]

1. Use Sectional Property Calc. (SPC) fuction

2. Click the ‘Add’ and ‘Modify’ buttons
   Intersecting objects must be cut off to calculate section properties. [Select all objects to breake / Do not break(N)] :
   
   Calculate Section Properties
   To calculate section properties, all intersections of objects must be disconnected.
   Therefore, when entering the 'Calculate section properties' panel, an action to disconnect the object will be required.
   

1. (Like CAD “Explode” effect)
   

2. When selecting an object, the object is disconnected and the ‘Calculate sectional properties’ window will automatically open.
   

1. If the object is already broken, select ‘Do not break(N)’ and the ‘Calculate section properties’ window will automatically open.

• Section Name : Enter the name of the section

• Section Type :
  There are three section types (Plane, Line, and Composite), and how to define the cross-section according to type is explained below.

SPC section definition of Plane section type

Info
SPC section definition of Plane section type

• Select External Object :
  Select the external closure object.
  Only the outermost closed section of the selected total object is recognized.

• Select Internal Object :
  Select the internal closed object.
  If there are multiple internal objects, select one closed section in turn.

• Mesh Density :
  Select Mesh Density.

SPC section definition of Line section type

• Define Thickness :
  Select the line object and enter the thickness.
  The entered thickness is temporarily applied to the line object and disappears when the ‘Calculate section properties’ window is closed. The preview retains the thickness applied.

• Define Close Section :
  Select the closed object. If there are multiple objects, select one closed section in turn.

• Specify Curve Precision :
  Curve precision refers to the degree of division when Spline and Ellipse must be divided into Line for calculation.

• Create with Steel Design Type :
  When Checked On, the ‘Design Group Setting’ tab is activated and you can define Top, Bottom, Right Web, and Left Web information

• .

  • When selecting a Top, Bottom, Right Web, or Left Web object, you can select a stiffener, and objects with a stiffener selected are created with a stiffener label.

SPC section definition of Composite section type

Info
SPC section definition of Composite section type

Tip
Composite Type is created using the created Plane Type and Line Type.

• Setting Material :
  When you click, the ‘Setting Material’ window is activated, and you can define the name of the material, modulus of elastic, Poisson’s ratio, etc.

  Image Added

  The Base option specifies the Base Material that will be the basis for substitution.
  (For composite sections, the materials must be replaced by one to calculate the section properties of the entire cross section.)

• 
  

• Base Material :
  The Base Material specified in the Setting Material window appears.

• Number of Parts :
  Select the number of parts.
