About Modifying a Spline
You can modify a spline by using the Spline tab, the shortcut menu, or moving interpolation points or selected entities of the control polygon. In the Spline tab, you can control the spline edit option to remain as interpolation points or a control polygon in the Sketcher window. Click, hold, and move the mouse to move an end point, an interpolation point, or a selected part of the control polygon to the desired locations. You can perform the following modifications to splines:
• Move interpolation points.
• Add points or vertices.
• Delete points or vertices.
• Manipulate a spline using control points.
• Create a control polygon.
• Delete a control polygon.
• Sparse a spline.
• Smooth a spline.
• Modify the coordinates of spline points.
• Read spline coordinates to a file.
• Get information about spline points.
• Interpret coordinate system as Cartesian.
• Interpret coordinate system as polar.
