Hi @andrei_costanJ33N8 .

Where did you define this section? Section definition or parametric section?

Best regards,

Hello,

I have an I section, and results are not corect (A, Ix, Iy, Iz, Iom) - my point of view.

hi @andrei_costanJ33N8 

could you briefly give the dimensions of the section, possibly share the model, say which value is false (value estimated by you).

Best Regards

Hi @andrei_costanJ33N8.

If you are in "thin walled" mode, you necesseraly have to draw your section only with line and then you modify the thickness.

Select all the line / right click / propeties / thickness

Best regards,
