Evaluate Curve

Creation method#

There are two options for creating Evaluate Curve node.#

• The first way to create Evaluate Curve 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.
  • pntOnCrv
• The second way is to select Evaluate Curve node from the menu that opens from the top left.
  • Menu > Tool > Curve Analysis > Evaluate Curve

Steps#

• Create Evaluate Curve node.
• Connect the curve to evaluate to the first port.
• Connect a parameter to the second port to evaluate the curve using either the parameter on the curve's domain or the length factor.
• Connect the boolean toggle, which is used for evaluating the curve either with the t parameter or with the length, to the third port.

After creating a node, connect the curve to be evaluated to the first port. Connect a parameter to the second port to evaluate the curve using either the parameter on the curve's domain or the length factor. Connect the boolean toggle, which is used to determine whether to evaluate the curve with the t parameter or with the length, to the third port. By default, the curve will be evaluated using the t parameter. On the output ports, you will receive the point on the curve at the specified t or length, the tangent vector at the specified t or length, the tangent perpendicular vector, the curve length from the start to the specified parameter or length, and the curve length from the specified parameter or length to the end.
