What determines the direction of Y/Z when defining a new profile in section definition? I am trying to define an H-beam with plates welded to the sides with the z axis pointing upwards in the same direction as the original web. When I look at the calc note the lcs is turned around 90 degrees compared to the original coordinate system when I started to draw the cross section.... It seems that it orientates the z-axis to be the weakest axis?
See attachment. The red arrows are the original coordinate system during drawing and the yellow ones is the new lcs after standardisation. I want these to LCS'es to be equal.

Currently the Section Builder module always calculates section properties setting the principal axis in such way that Iy>Iz. The request for option that would allow for decision which axis is Y and which Z (rotating the originally assumed coordinate system by 90 deg) is on the wish list for new versions of Robot.

This was bad news. It makes it harder to work with defined sections and releases...
