Section definition-Issues with the axis

ana.ramiro — Tue, 12 Mar 2024 18:16:05 GMT

Hi all, I am trying to get the section properties of a non-standard steel section that I drew in AutoCAD. However, when I imported the section to Robot Structural Analysis I got two pair of axis that don't match, and Z and Y appear in opposite directions. Could you please let me know how to ensure that the axis match and with regard to which set of axis are the results obtained? Please see images below:

Hi @ana.ramiro

Robot always considers the major inertia around the y-axis. If you draw the rotated section, the axes will coincide. Then you rotate it however you want in the structural model.

Best regards,
