The Curves ExtendCurve tool extends selected edges at both ends by a given distance.

1. Select one or more edges in the 3D view.
2. There are several ways to invoke the tool:
   • Press the Curve extend button.
   • Select the Curves → Curve extend option from the menu.
3. An ExtendedCurve object is created for each selected edge.
4. Optionally edit the values in the Property editor to adjust extension lengths and types as well as the output shape (see Properties below).

A ExtendCurve object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

Base

• DatiEdge (LinkSub): Input edge to extend.
• DatiOutput (Enumeration): Output shape.
  • SingleEdge (default): A single continuous curve.
  • Wire: Separate curves.

Beginning

• DatiLength Start (Float): Start Extension Length.
• DatiType Start (Enumeration): Start Extension Type.
  • Straight (default): The extension is a straight line.
  • G2 curve: The extension is another curve that adopts the local curvature of the input edge at their common vertex (G2 continuity).

End

• DatiLength End (Float): End Extension Length.
• DatiType End (Enumeration): End Extension Type.
  • Straight (default): The extension is a straight line.
  • G2 curve: The extension is another curve that adopts the local curvature of the input edge at their common vertex (G2 continuity).
