What the node takes in, from wires or typed values.

Curve

Curve

Curve to measure

Parameter

Number

Default 0.5

Parameter along curve

Outputs

2

What the node gives out, to wire into other nodes.

Length 1

Number

Curve length from start to parameter

Length 2

Number

Curve length from parameter to end

Creation method#

There are two options for creating a Length Parameter node.#

  • The first way to create a Length Parameter 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.
    • len , crvLen , lp
  • The second way is to select a Length Parameter node from the menu that opens from the top left.
    • Menu > Tool > Curve Analysis > Length Parameter

Steps#

  • Create a Length Parameter node.
  • Connect the curve whose length by parameter you want to find to the first port.
  • Connect the parameter along curve to the second port.

After creating a node, connect the curve whose length by parameter you want to find to the first port. To the second port, connect the parameter along curve. On the output ports, you will get a curve length from curve start to parameter and from parameter to curve end.
