ability to move along X, Y, and Z axes is called translational freedom. The
ability to rotate around the axes is called rotational freedom.
Whenever you apply a constraint to a component in an assembly, you remove
one or more degrees of freedom. A component is fully constrained when all
degrees of freedom (DOF) have been removed.
Autodesk Inventor does not require you to completely constrain any
component in an assembly. You can save time by removing only critical DOF
for your model. There are situations in which you do not remove DOF. For
example, do not remove DOF so that Inventor can correctly interpret the
design intent when the assembly is animated, or to leave yourself design
flexibility for a later phase in the design process.
To show the DOF symbol for all components in an assembly, select Degrees
of Freedom from the View menu.
The straight lines with arrows at one end represent the translational degrees
of freedom along the X, Y, and Z axes. The arcs represent rotational degrees
of freedom about each axis.
Unconstrained Drag
You can move unconstrained components by dragging them in the graphics
window.
Partially constrained components sometimes need to be moved or rotated to
facilitate constraint placement. Use the Move Component and Rotate
Component tools to temporarily release all assembly constraints so you can
reorient a component. Any assembly constraints that have been placed are
reapplied to the assembly as soon as you click Update.
Constrained Drag
Dragging a single constrained component causes other components in the
assembly to move, according to the relationships defined by their assembly
constraints. This technique is very useful in determining the suitability of
assembly constraints placed on a component.
Drag a component after applying an assembly constraint to quickly gauge the
effects of the constraint. Grounded components cannot be moved in this
manner.
