This must be something very basic I am missing: I am inserting the 'Grid vertical' object (in the US library inside Doors-Windows>Curtain Walls) and I cannot drag the editable hotspots around. Is it some preference, some 3D window or engine setting?
(I am trying to drag the pieces around because I first tried filling in the parameters for a grid with irregular spacing in the z dimension and the object is obviously having some problem with the math.)
