This command allows to know different parameters from the analyze of area moments of inertia (area moments, polar and principal area moments) from a profile or a section.

 

Creation stages / Use:

 

Click the icon or select the Analysis > Analyze area moments of inertia... command from the drop-down menu.

 

  1. Select a face or a 2D sketch.

  2. Select the direction. The analysis is done regarding this direction.

  3. Check Center of inertia to use the center of inertia which is automatically calculated or select Point to select a point.

  4. Validate by clicking .

 

 

The direction must be parallel to the section or the sketch plane.

 

 

Parameters values depend on the geometry, the reference point and the direction. These values can't be manually changed.

 

 

  • The parameters unit can be modified in the unit section of document options.

  • To know the Area moments of inertia, to create parameters and an operation, use the Tools > Area moments of inertia...command.

  • The result can be selected, copied and pasted in a text document or other.
