Rotate couplers with respect to the bar end for precise modelling with clash avoidance.
In 3D views, the coupler geometry is always aligned to the bar end. When rotating the coupler, this is the default position.
To create complex geometry and display it in a realistic way in 2D views, you can edit the coupler family and uncheck the Align to View option.
This feature is described on the
product road map.
