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.
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。
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.
