Snap a brush to a curve
 
 
 

Hold down + (Windows) or + (Mac), click the curve and drag along the curve.

When you are sketching, you can snap a brush to a curve (or surface isoparametric curve or curve-on-surface). This allows you to use curves as sketching guidelines.

To snap a brush to a curve

  1. With a brush active click the button to the right of the prompt line, or hold down + (Windows) or + (Mac), to activate curve snapping.
  2. Move the stylus so the brush profile is near the curve.

    The brush profile will jump onto the curve.

    TipTo set the brush curve snap tolerance, choose Preferences > General Preferences , then choose Paint from the left side of the option window, and set Brush Curve Snap Tolerance to the number of pixels the brush cursor must be from a curve in order for the brush profile to jump onto the curve.
  3. Drag the stylus along the curve.
  4. Click the button again, or release + (Windows) or + (Mac), to de-activate curve snapping.
    TipYou can snap to invisible curves (see ObjectDisplay > Visible ) or curves on invisible layers (Layers > Visibility > Invisible ).
