Standard
The solver will attempt to find a solution that localizes the changes around the nodes being dragged. The movement of the dragged nodes will not be “propagated” to nearby nodes. Adjacent sets and geometries within a model may be moved relative to each other (if they are free to do so).
Rigid
The solver will attempt to move all nodes connected to the nodes being dragged with the same transformation, i.e., the movement of the dragged nodes will be propagated onto all unfixed connected nodes. The overall effect will be that under-constrained models move rigidly. If none of the connected geometry is constrained to fixed geometry then all of it will move rigidly. If some of the connected geometry is constrained to fixed geometry then as many nodes as possible will be moved rigidly.
Localized
In this mode the solver will attempt to move the geometry with the transform provided and make no attempt to minimize the number of geometries that are moved. It will not propagate the transform onto connected nodes. Generally, no propagation solving will transform the dragged geometry as specified more often than minimum move solving but less often than maximum move solving.
Relaxation
The solver will find a solution that requires many geometries to move. This mode can be helpful when large movements are necessary and the other drag modes will not find a solution.
