Converting Curves

You can create a curve by approximating a set of input data and manually move, insert, or delete cell boundaries to optimize the structure of the result.

This task shows you how to:

Before you begin: Open a 3D shape containing a multi-segmented curve with high segmentation.

Manage Cell Boundaries

  1. From the Modification section of the action bar, click Curve Conversion .
  2. Select the multi-segmented curve.
  3. Select Single-Result in the Cell Reduction Parameter list on the Output Tab.
  4. Select Manage Cell Boundaries in the Cell Structure list on the Options tab.
    Green manipulators are displayed at the input curve boundaries.

    The manipulator color indicates the current status of the corresponding cell boundary:

    Green Original input cell boundary
    Red Deleted input cell boundary
    Blue Moved boundary
    Grey Original position of a moved boundary
    Yellow Inserted boundary

  5. Move cell boundary: Move a manipulator along the curve between the two adjacent manipulators.
    After this operation the colors will change.

    The original position is displayed in grey color (and can no longer be changed).

    The new position is displayed in blue color. The blue manipulator can be moved until the desired position is reached.

  6. Delete cell boundary: Right-click a manipulator and select Delete.
    The color of the deleted manipulator changes to red.

  7. Insert cell boundary: Right-click a manipulator and select Add before or Add after to insert a new cell boundary before or after the current manipulator at the mid point of the next cell.
    The new manipulator is displayed in yellow color.

  8. Move inserted cell boundary: Move the inserted boundary along the curve until the desired position is reached.

Add/Remove Cell Boundaries

  1. Select Add Cell Boundaries in the Cell Structure list.
    The curve is emphasized and cell boundaries are displayed as grey squares.
  2. Click the curve.
    A cell boundary is added at the selected position.

  3. Select Remove Cell Boundaries in the Cell Structure list.
    The cell boundaries are displayed as cyan squares.
  4. Move the mouse onto the cell boundary to be deleted.
    The cell boundary will be displayed in orange. Clicking the selected cell boundary deletes it.

  5. Select again the Manage Cell Boundaries option to display added and removed cell boundaries.
