The Proportional Modification
Tool lets you move a manipulator and have the surrounding
control points follow proportional to their distance from the moving
point. This effect is controlled by the Distance Cutoff setting.
“Proportional modification” is sometimes shortened
to propmod.
To
transform the selected components proportionally
- Select
the components you want to modify. Only the selected components
are influenced by the tool.
- Select
Modify > Transformation Tools > Proportional Modification Tool > .
- Use
the options in the Tool Settings panel to control
how distance is measured and how quickly the influence of the manipulator
falls of with distance:
- Set
the Modification Type to World to
calculate distance in world space. Set it to Parametric to
calculate distance across the surface (Parametric only works on
NURBS).
- Set Modification
Falloff to Linear to
have influence fall off at a steady rate. Set it to Power to have
influence fall off very quickly.
- Press
Insert or Home to change the manipulator to pivot point mode. Drag the
manipulator to move it where you want the center of influence. Press Insert
or Home again to change the manipulator back to normal mode.
- Use
the other handles on the manipulator to move or scale the selected components
based on their distance from the manipulator.
