Spline 样条曲线

-

Creates a smooth curve that passes through or near a set of fit points, or that is defined by the vertices in a control frame. 创建经过或靠近一组拟合点或由控制框的顶点定义的平滑曲线



Splines are defined either with fit points, or with control vertices.
样条曲线使用拟合点或控制点进行定义


Home tab > Draw panel expand > Spline Fit
默认选项卡 > 绘图面板下拉菜单 > 样条曲线拟合


Pick first point
拾取第一点


Pick multiple points
拾取多点

Press [Enter] 按【回车】


Closed Spline 闭合样条曲线


Home tab > Draw panel expand > Spline Fit
默认选项卡 > 绘图面板下拉菜单 > 样条曲线拟合


Pick first point
拾取第一点

Pick multiple points 拾取多点
Command Line： Close 命令行：Close


All rounded corners when it close 选择 Close 后所有端点变圆角

Edit Spline 修改样条曲线


Double-click on spline to enter Edit mode
双击样条曲线


Select convert to Polyline
选择转换为多段线

The precision value determines how closely the resulting polyline matches the spline
Valid values are any integer between 0 and 99
精度值决定多段线的形状多靠近样条曲线
精度值范围：0至99

A high precision value will decrease performance 更高的精度值降低软件的表现
