You can rotate plumbing fixtures by clicking and dragging them.
To rotate a plumbing fixture:
Select the fixture you want to rotate.
Hover your pointer over the triangular
grab handle to display the Rotate cursor.
Tip: If the triangular grab handle is in close proximity to the square grab handle, you may want to zoom in on the element to distinguish between the two grab handles.
Click and drag to rotate the fixture.
When the fixture is at the desired rotation, release your mouse button.
