Spline Sketch

样条素描

The Spline Sketch tool, for which you don’t have to switch to the Use Points mode (it can be used in the normal Use Model mode), replaces the previous Spline Freehand tool and can also do a lot more. The Spline Sketch tool can be used to draw directly in the Viewport (and works especially well in conjunction with tablets) and can be used to edit (e.g., redirect or smooth splines, connect splines or spline segments) existing splines.

样条素描工具，你不必切换到使用点模式(它可以在正常的使用模式) ，取代以前的样条徒手工具，也可以做更多。样条素描工具可以用来直接在视图端口中绘制(特别适合与平板结合使用) ，也可以用来编辑现有的样条(例如，重定向或平滑样条，连接样条或样条段)。

When a new spline is created, a Bézier spline will be created by default. When existing splines are edited, their original spline type will be maintained.

当创建一个新的样条时，默认情况下会创建一个贝塞尔样条。编辑现有样条时，将保留原样条类型。

The Snap settings will be observed by the Spline Sketch tool. The 3D Snapping function is especially useful because it lets you draw a spline directly onto an object surface.

快照设置将通过样条素描工具进行观察。3D 捕捉函数特别有用，因为它可以让你直接在物体表面上绘制样条曲线。

Use

使用

After activating the tool, click and drag in the Viewport to start drawing a spline. As soon as you release the LMB the spline will be created.

激活该工具后，在 Viewport 中单击并拖动以开始绘制样条。只要您释放 LMB，就会创建样条。

When sketching in space, the spline will always be drawn perpendicular to the angle of view on the layer that runs through the world origin.

当在空间素描时，样条将始终绘制垂直于视角的层，通过世界起源。

The following functions are available:

有以下功能:

1. A spline can be grabbed at any location and edited from that location (see also below). 样条可以在任何位置获取并从该位置进行编辑(另见下文)
   
2. Separate splines and spline segments of a spline can be connected at their ends. If a spline segment’s start and end points are connected the spline will be closed. 分开的花键样条和花键段可以在它们的末端连接。如果一个花键段的起点和终点是连接的，那么花键就会闭合
   
3. Separate splines and spline segments of a spline can be connected anywhere along the spline. 单独的花键样条和花键段可以沿着花键的任何位置连接
   
4. Pressing the 按下Shift 转移 key will temporarily switch to the Spline Smooth tool (the previously defined settings for this tool will be applied). 键将临时切换到样条光滑工具(此工具将应用先前定义的设置)
   

If you want to unify spline segments or 2 separate splines, select the splines first. The start and end points of the tool’s marker must lie on different splines or segments. 2 separate spline objects will be combined into a single spline.

如果要统一样条线段或两个单独的样条线，请先选择样条线。工具标记的起始点和终止点必须位于不同的样条线或段上。2个独立的样条对象将组合成一个单一的样条。

Note the tool’s cursor at the start and end of the operation:

注意操作开始和结束时的工具光标:

The radius that can be defined in the tool’s menu (or interactively using the MMB) is the area within which the tool can affect splines. In the preview you will that a curve defines 1 to 2 points in the radius with the spline (colored dots) and the cursor itself. The points define possible connecting points for the newly created spline. The curve itself is only a reference. What’s important is the direction in which the cursor moves when you click. If it moves left a new spline shape will be created similar to the shape to the right. If the cursor is moved away from the spline (with the LMB pressed) everything at the left of the right dot will be deleted.

可以在工具菜单中定义的半径(或交互式地使用 MMB)是工具可以影响样条的区域。在预览中，您将看到一条曲线用样条(彩色点)和光标本身在半径中定义了1到2个点。这些点为新创建的样条定义了可能的连接点。曲线本身只是一个参考。重要的是当你点击鼠标时光标移动的方向。如果它向左移动，将创建一个类似于右边形状的新样条形状。如果光标从样条上移开(按 LMB) ，右点左边的所有东西都会被删除。

However, if the cursor is moved back over the existing spline (see image below) or over a new spline segment before the operation is completed, the cursor’s circular range indicator will again be displayed and the Spline Sketch tool can be attached to the existing spline or the new spline segment.

但是，如果在操作完成之前将光标移回现有的花键(见下图)或移到新的花键段上，光标的圆形范围指示符将再次显示，花键草图工具可以附加到现有的花键或新的花键段上。

In the example above, a spline segment was added to an existing spline. The direction in which the cursor is moved for this operation is important. The movement in the center image should not be to the left in the direction of the beginning of the spline but to the right towards the spline end (note the blue preview within the tool’s radius that indicates the direction to be used).

在上面的示例中，样条段被添加到现有的样条中。对于此操作，光标移动的方向很重要。中心图像中的移动不应该在样条开始的方向上向左移动，而应该向样条结束的方向右移动(注意工具半径内的蓝色预览，它指示了要使用的方向)。

The tool’s range indicator can be turned off temporarily by pressing the Ctrl/Cmd key or setting Radius to 0. This can be necessary, for example, if you want to create a new segment in close proximity parallel to existing splines.

可以通过按 Ctrl/Cmd 键或将半径设置为0来临时关闭工具的范围指示器。例如，如果希望创建与现有样条线非常接近的新段，则可能需要这样做。
