| 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.

(SPC) fuction 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.

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.

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.

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 AddedThe 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.)

CIVIL section properties calculation and table setting |
| Note |
|---|
Section property calculations are not calculated according to the length units below.
It is calculated by recognizing only the numbers drawn on the drawing, and when the unit is changed, the calculated result is simply converted to units.
If you draw a drawing in 'mm' units and then calculate it in 'm' units, the result will be incorrect. |
Force Unit : This is an option that specifies the force unit of the table, such as KN, kgf, tonf Length Unit : This is an option that specifies the length unit of the table, such as mm, inch, or ft. Precision : This is an option to specify the number of decimal places to express. Layer : Option to specify the Layer for the table. Font : Option to specify the font for the table.
