# 样条曲线
通过使用“样条曲线”工具，可以在空间中或在其他对象上创建有机草图。
样条曲线基于至少 3 个内插点绘制。连接的几何图形将简化，从而在指定点之间创建平滑的有机曲线。与其他绘图工具一样，通过在绘图时捕捉到三维点，即可以三维形式绘制样条曲线。
要指定距离，请开始键入尺寸值，然后在“编辑尺寸”对话框中点击“确定”或按 Enter 键。
样条曲线还可以自行闭合，从而创建面。
## 编辑样条曲线
还可以通过在已放置的样条曲线上单击鼠标右键，然后选择底部的“编辑接头”，来修改该样条曲线的点：
“编辑接头”夹点将显示，以便可以移动它们。新的样条曲线在编辑时会显示为轮廓。
要完成编辑，请通过单击进入空间或按 ESC 键以退出该工具。新的样条曲线即会替换当前样条曲线。
