Creating Curves on Support

You can easily create curves on a support mesh, to be used in a network of curves.

Notes:
  • The output is a Curve On Support (different from Curve on Mesh).
  • All curves on support can be edited in Curves Network Preparation, but also as standard curves.
  • To add connection sections, we suggest you create several simple curves to be connected, instead of creating one complex curve with many segments.

  1. From the Wireframe section of the action bar, click Curves Network Preparation and select a Mesh.
  2. From the context toolbar, select Curve on Support .
  3. Pick successive points on the mesh.
  4. Tune the smoothness of the curve from the context toolbar.

    For more information, see Ensuring Curve Quality.

  5. Whenever required, use the snap mode to constrain any point on other existing points, curves, fictive edges, or edges of existing surfaces.

    Tip: Move the pointer near a curve (extremity or intermediate point) to automatically snap on this point.

    Continuity conditions are computed automatically and specified.
  6. Optional: Use Ctrl-Z to undo the last pick.
  7. Edit the curve as required.
    • Add new points at the end, or insert a point between existing ones.
    • Move or delete existing points.
    • Adjust the tangent of an existing point.
    • Set point/tangent constraints at extremities.
    • Adjust the mathematical definition.
    • Use analysis tools.
    • Extend the current curve up to a target element (See Extend or Extrapolate)
  8. Optional: In some specific situations such as splitting an area or filling a gap between curves, drag the cursor for a quicker creation of the curve.
    Snapping on existing intersecting curves is automatic.
