About Using the Dragger
The dragger is a graphical control available in 3D part and assembly modes for precisely moving or rotating geometry. A dragger may appear as an arrow, a combination of arrows and rings, or as a complete unit with arrows, rings, and a middle sphere. These individual units are called handles. The handles of a dragger enable movement in one or more degrees of freedom (DOFs). They support linear, planar, free, translation, and angular movements.
If a command uses the dragger, the appropriate handles appear when you click an entity. The handles that you can use for the operation appear highlighted in red, green, and blue in x-, y-, and z-directions respectively. As you pull or rotate the highlighted handle, the changes to geometry are shown dynamically in the graphics window.
If the dragger is attached to a planar surface, you can move and snap the geometry using a linear handle to the following references on the model:
Vertices in any direction
Datum points in any direction
Edges or axes parallel to the planar surface
Edges or axes perpendicular to the linear dragging direction
Planar surfaces or datum planes parallel to the planar surface
Planar surfaces or datum planes perpendicular to the linear dragging direction
When moving a geometric entity using the dragger, snapping occurs only in the following scenarios:
When the linear handle is normal to the geometric entity and the dragger is on a planar surface
The rotation handle is around a selected axis
