Surface Constraint Tools for Blender 2.80+

Surface Constraint Tools is designed to simplify the process of modeling on the surface of another mesh. Therefore, you may find it useful for retopology tasks.

For example, the “Surface Constraint” section of the UI, as seen above, allows a user to select a target on which to constrain the vertices of the active mesh. The “Mesh Brush”, “Shrinkwrap”, and “Smooth Vertices” operators comply with this constraint. Moreover, if you would like for the constraint to affect all mesh operators, simply enable the button with the car icon.
