Spine Spine conforms the stroke to a smooth curve between the point where you press the pen down and the endpoint. I will often use Pinch with Backtrack Line and SnapToTrack enabled to create sharp, straight lines on mechanical forms. Hold Shift to conform the line to a 45-degree angle as you draw.

Line Line constrains the stroke to a straight line. Anything intersecting this plane will be sliced by the tool. Plane Plane applies a virtual plane to the surface.

You can turn this off for total freedom in your stroke, but often you want to confine your stroke to the path you draw for accuracy.įigure 10.48 The Polish brushes in action SnapToTrack forces the stroke to conform to the line or curve you draw. This ensures that the stroke will continue to affect the surface even when it is curvy and not flat to the camera. When working with Backtrack, you’ll find it best to turn Track Curvature up. Backtrack is enabled under Stroke ^ LazyMouse (Figure 10.49). Backtrackīacktrack is a new subset of LazyMouse that helps you create straight lines or force your stroke to conform to a path. They help to reduce the sharp edges while retaining the sense of structural form in the sculpture. Notice how in Figure 10.48 the Polish brushes help refine the transitions between the Trim brush planes. The Polish brushes often help support the other hard-surface brushes. The surface is relaxed along the stroke to form a flat surface.

The hard edges will be maintained as the stroke is moved along the surface. The Polish brushes will respect all edges. Figure 10.47 shows the Trim brushes in action. Only two Trim brushes will respect the document plane (TrimFront and TrimNormal) whereas all others will evaluate the surface normals along your brush stroke. The Trim brushes will trim away at the surface while respecting the surface normals and maintaining an edge along the stroke.
