简介¶

Draw Mode is the mode in Grease Pencil that allows you to draw in the 3D Viewport. This mode is actually the only one in which new strokes can be created.

在绘图模式下已经无法选择笔画，编辑笔画时必须使用编辑模式 or 雕刻模式。

绘画模式¶

3D Viewport Mode selector: Draw Mode.¶

Draw Mode is selected with the Mode menu in the 3D Viewport header. Once Draw Mode is activated, the Toolbar of the 3D Viewport will change to Draw Mode specific panels. Also a circle with the same color as the active material will appear and follow the location of the cursor in the 3D Viewport.

要创建新笔划，您必须在工具栏中选择一个绘图工具。最常见的是 Draw tool 用于自由手工绘图，但还有许多其他工具可用于绘图，填充区域和擦除笔划。还有一些工具可以创建基本形状，如直线，圆弧，曲线，方框和圆形。

请参阅 Toolbar 来获取更多信息。

描边位置和方向控制¶

Drawing in a 3D space is not the same as drawing on a flat canvas. When drawing with Grease Pencil you have to define the location and orientation of the new strokes in the 3D space.

笔划放置¶

笔划放置选择器定义3D空间中的新笔划位置。

请参阅 Stroke Placement 来获得多的信息。

绘图平面¶

绘图平面选择器定义新笔划将被限制的平面(方向)。

请参阅 Drawing Planes 来获得更多信息。

引导¶

绘制新笔划时，可以激活不同的参考线类型以帮助您。

请参阅 Guides 来获得更多信息。

绘图选项¶

通用绘图选项。¶

背面绘图: 启用后，将在图层中的所有笔划下方绘制新笔划。例如，当您想要在字符下方的线条笔划下方使用填充材质进行绘制时，它们位于同一图层上。

添加重量数据

启用后，根据当前顶点组和权重将权重数据添加到新笔划。如果未选择顶点组，则不添加重量数据。

例如，在剪切动画中用于在同一顶点组上添加新图形而不需要在之后创建它。

请参阅 Weight Paint Mode 来获得更多信息。

加图: When creating new frames adding strokes with drawing tools, the strokes from the previous/active frame are include as a basis for the new one. When erasing existing strokes using Additive Drawing a new keyframe will be added.

AutoMerge: Joins new strokes with the beginning or end of previously drawn strokes in the active layer.
Interpolate: Popover that contains tools and properties to automatically add breakdown keyframes between normal keyframes. See Interpolating Strokes for more information.
