It is interesting that so few Poser users can manage magnets but no one seems to have trouble with a product like Natural Bounce which is just a magnet set where the magnet part geometries have been changed to something more coherent to users... the magnet is a ball shaped handle in smooth Shaded Mode, the base is a flattened disc also in solid shaded mode, and the zone is a a sphere but is hidden or wireframed.

Give people an outline view horseshoe. an ugly rectilinear base in shaded mode that seems to function without regards to its spatial orientation, and an outline zone and they don't know what the hell they are doing... can't follow the analogy. Offset the base from the zone so that the relationship of the magnet handle ball is explicit to the base and they understand it. They now understand that the zone interacts with the target mesh and this is controled by the magnets interaction with the base... somehow this is obscured when the base, zone and magnet are all intersecting the target mesh.

Even the shape of the base (rectangular prism as opposed to a non-directional disc) and the magnet (horseshoe instead of a simple ball or cone or pyramid) establishes false analogy and false directionality... the ease of use dirrived from shaping a deformer as a ball or cone as opposed to a horseshoe is no small thing in terms of human/perception based design.

The magnet is classic coders design, symbolic... the cone is user interface design, pseudo ergonomic... extraneous detail is suppressed and form supports function. I swear that if the base were a disc or ball, the zone was default wire frame or now in P8 a translucent solid, and the "magnet" was a cone pointing at or "sitting on" the base everyone would be using magnets!
