Use this to paint multiple strokes in a grid on a NURBS or polygonal surface. The grid settings are based on the options specified below. For more information, see Automatically paint multiple strokes on a surface.
In the
Modeling menu set, select
Generate > Auto Paint > Paint Grid > 
to open the
Auto Paint Grid window, which provides the following options:
- Spans U, Spans V
-
Sets the number of lines to draw in U and V to define the grid.
- Curve Degree
-
Defines the degree of curve on surfaces generated. The higher the degree, the smoother and tighter the curve.
- Strokes Per Span
-
Sets the number of strokes to create along each grid line.
- Points Per Curve
-
Sets the number of points on each stroke path curve (curve on surface) created.
- Grid Smear
-
Sets the amount of displacement of the lines using a 2D noise function. When this option is 1.0 the lines are randomized to the full width of their row or column.
- Smear Frequency
-
Sets the frequency of the noise applied with Grid Smear. Lower values create a smoother noise offset.
- Sample Density
-
Sets the Sample Density attribute of the created strokes. Higher values result in smoother strokes and a greater tube density. For more information see Modify stroke settings for existing strokes.
- Surface Offset Min, Max
-
Sets a range of Surface Offset values. The Surface Offset for created strokes is randomized between these values. You could use this, for example, to create a cloud of strokes about a surface. For details on Surface Offset, see Set up to paint in 3D.
- Edge U, Edge V
-
Turn these options on to create the boundary lines of the grid in U and V. When these options are turned off, strokes are not created along the boundary lines.
- Equalization
-
Modulates the Sample Density for the created strokes based on the length of the stroke path curves (curves on surface). This helps keep tubes more evenly distributed.
- Share One Brush
-
Turn this option on to make all strokes share one brush. When this brush is off, a separate brush is created for each stroke. For information on brush sharing, see Make strokes share or unshare the same brush.
