The 3D UV Grab Tool allows you to move an object's UVs by dragging a brush over them in the Viewport. UVs are affected on a gradient around the brush.
Use these options to set what happens when you select the.
Sets the radius of the tool.
Hotkeys: B + drag or MMB-drag left/right to adjust the brush size. B + MMB-drag left/right or Ctrl + MMB-drag left/right to adjust the brush size from 0.
Determines how much the tool affects the surface. Depending on the tool, this value represents either a percentage of the maximum power available or a height expressed in world space units.
Hotkeys: M + drag or MMB-drag up/down to adjust the brush strength. M + MMB-drag up/down or Ctrl + MMB-drag up/down to adjust the brush strength from 0.
Reflects a stroke from one side of a model to the other, along the specified axis. See Sculpt using symmetry.
Strokes are not reflected.
Reflects strokes across the local space X-axis.
Reflects strokes across the local space Y-axis.
Reflects strokes across the local space Z-axis.
Reflects strokes across the world space X-axis.
Reflects strokes across the world space Y-axis.
Reflects strokes across the world space Z-axis.
Controls the stamp frequency/continuity on a stroke. Depending on the Size and Falloff settings for a tool, the Spacing can be set to a higher value to refine the tool behavior and improve the appearance of the stroke. The default setting is 6.25 and ranges between 0 and 100. The higher the setting, the more gaps appear on the stroke, depending on the tool settings.
Helps to produce a smoother stroke by filtering mouse/stylus movement. When on, a vector displays on the tool cursor and no stroke appears until you drag a distance equal to the length of the vector. The length of the vector is set by the Distance setting. See Produce smooth tool strokes.
Sets the length of the Steady Stroke vector on the tool cursor.
Lets you specify how the tool effect diminishes (or not) from its center point to its outer edge. The falloff is represented as a curve that can be edited. See also Adjust sculpting tool falloff.
The brush measures distance by drawing a straight line from the center of the brush to each vertex within the brush radius. Vertices are assigned a falloff value depending on how far away they are from the center point. Volume falloff affects all the meshes that are within the brush radius, even if there is no bridge between separate meshes.
Constrains points to the Falloff curve grid.

Specifies how small the tool is when the lightest pressure is applied to the pen, expressed as a percentage of the tool’s Size setting. For example, a Min Brush Size % of 100 indicates there is no size variance, regardless of the pressure applied.
Specifies how weak the tool strength is when the lightest pressure is applied to the pen, expressed as a percentage of the tool's Strength value. For example, a Min Brush Strength % of 100 indicates there is no strength variance, regardless of the pressure applied.
Orients the tool cursor display (in the 3D View) along the normal of the face under the center of the tool's radius. This setting Influences cursor display only, and does not influence the effect of the brush on the surface.
