In the 3D Viewport, sketches on the active layer can be converted to geometry, based on the current view settings, by transforming the points recorded when drawing (which make up the strokes) into 3D space. Currently, all points will be used, so it may be necessary to simplify or subdivide parts of the created geometry for standard use. Sketches can currently be converted into curves in Object Mode.
创建2阶3位 NURBS 曲线 (亦即类似折线)。
创建贝塞尔曲线，控制柄类型为 "对齐" (亦即同样类似折线)。
Bézier curve with straight line segments (auto handles).
如果要将草图转换为网格，只需选择 NURBS ，然后再将得到的曲线转换为网格。
The Bevel Depth to use for the converted curve object.
The Bevel Resolution to use for the converted curve object.
Will scale weights value so that they fit into the (0.0 to 1.0) range.
Multiplier for the points' radii (set from the stroke's width).
Will create a single spline, i.e. curve element, from all strokes in active Grease Pencil layer. This is especially useful if you want to use the curve as a path. All the strokes are linked in the curve by "zero weights/radii" sections.
Grease Pencil stores "dynamic" data, i.e. how fast strokes are drawn. When converting to curve, this data can be used to create an Evaluate Time F-curve (in other words, a path animation), that can be used e.g. to control another object's position along that curve (Follow Path constraint, or, through a driver, Curve modifier). So this allows you to reproduce your drawing movements.
Link Strokes has to be enabled for all timing options.
The path animation will reflect to original timing, including for the "gaps" (i.e. time between strokes drawing).
The path animation will reflect to original timing, but the "gaps" will get custom values. This is especially useful if you want to shorten large pauses between some strokes.
生成的路径动画 长度，单位帧。换句话说，就是 解算时间 最大值。
When enabled, the path animation will last exactly the same duration it has taken you to draw the strokes.
When Realtime is disabled, this defines the end frame of the path animation. This means that the drawing timing will be adjusted to fit into the specified range.
Custom Gaps only. The average duration (in frames) of each gap between strokes. Please note that, the value will only be exact if Realtime is enabled, otherwise it will be scaled, exactly as the strokes' timing is.
