Creation method

There are two options for creating a Loft Surface node.

  • The first way to create a Loft Surface node using the search list, which is opened by double left-clicking in the workspace. You can write the name of the node you need, or words associated with this node.
    • loft, srf, srfLoft
  • The second way is to select a Loft Surface node from the menu that opens from the top left.
    • Menu > Tool > Surface > Loft Surface

Ports

  • Curve 1, Curve 2, … — Section curves (at least two). Add more curves via “add port” in the port menu.
  • Degree — Maximum degree of the resulting surface (default: 2).
  • Condition — Continuity at first and last profile: Free, Tangent, Normal, Smooth (default: Free).
  • Parametrization — How to parametrize along sections: Chord, Centripetal, Iso (default: Chord).
  • Ruled — Linear interpolation between profiles, developable surface (default: false).
  • Closed — Connect last profile back to first for a closed tube (default: false).

Output: Surface — The resulting loft surface.

Steps

  • Create a Loft Surface node.
  • Connect the first curve with which we want to create surface to the first port.
  • Connect the second curve with which we want to create surface to the second port.
  • Add a port for additional curves using the "add port" function in the port menu and connect other curves to the added ports.

After creating a node, to the first port, connect the first curve with which we want to create surface, connect the second curve with which we want to create surface. For more than two curves, you need to add ports using the "add port" function in the port menu and connect other curves to these ports. On the output port, we will get the result surface all the curves.

  • Create a Loft Surface node.
  • Connect the first curve to the first port and the second curve to the second port.
  • For more than two curves, add ports with “add port” in the port menu and connect the curves.
  • Optionally set Degree, Condition, Parametrization, Ruled, or Closed.
  • The result surface appears on the output port.
