Soft Drag
Soft Drag is a tool preset that consists of the Move tool combined with the Screen Falloff.
Using Soft Drag
You can access Soft Drag from the Deform tab of the Modo Tools toolbar or by choosing Edit > Deform > Soft Drag.
Activate the tool, then click and drag in the 3D viewport to drag out the elements you need. You can select vertices, edges, or polygons, and then drag them to affect their neighbors to a greater or lesser degree based on the Screen Falloff.
You can use the right-mouse button to define the Screen Falloff's circle.
Note: Enable Transparent in the Screen Falloff section for the Soft Drag selection to happen through the mesh. With Transparent disabled, this tool preset only affects geometry facing the view.
