We already see that there is a problem with Edit/Placement for some Arch Object like Arch Section
There is the same sort of problem Axes System :
Create an Arch Structure object
Create an Axis System for that object
Select Axis system, Edit/Placement, rotate 90° along Z axis, valid.
> The Axis rotate to 180° along z axis, but his Placement properties is 90° along Z axis. The Structural system associated rotate to 90°, but that say it don't follow the Axis system.
> And Undo, place the axis to 90° along Z axis, but his Placement properties is 0° along Z axis. The Structural system associated return to 0°, but that also say it don't follow the Axis system.
Same with an Arch Structure if it is the children of an Axes system, but only if the Axe system have already a placement different from the origin...
Create an Arch Structure object
Create an Axis System for that object
Rotate "manually" the axe system, like 30° along Z axis
Now Edit/Placement the children Arch Structure, like 30° along X axis and apply.
> The Axes system is impacted by the placement ...
> Structural system is impacted by the placement of children Arch object, but not by the Axis system displacement.
