About the Spline Modification User Interface
To modify a spline:
• Double-click the spline.
• Select the spline, right-click in the Sketcher window and click Modify.
Commands
Use the commands to specify interpolation or control points when changing x or y coordinates. In addition, you can perform the following functions:
• Click
to create a control polygon.
• Click
to modify spline using interpolation points.
• Click
to modify spline using control points.
• Click
to show a curvature analysis.
Tabs
• Point—Change the x and y coordinates for interpolation. Also, move points to an absolute value or relative to the current value.
• Fit—Remove redundant data by the following methods:
◦ Sparse—Remove within a deviation tolerance.
◦ Smooth—Remove by averaging.
• File—From the File tab you can:
◦ Associate spline points with a coordinate system
◦ Read point coordinates from a file
◦ Save point coordinates
◦ Display coordinate information
◦ Change the coordinate system to Cartesian or Polar.
Shortcut Menu
Right-click the Sketcher window to access the shortcut commands:
• Add Point—Add a point.
• Delete Point—Delete a point (includes end points).
• Pick From List—Open the Pick From List dialog box.
