Creation method#
There are two options for creating an Arc SED node.#
- The first way to create an Arc SED node is 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.
- arc2Pnt , direction , arcSed
- The second way is to select an Arc SED node from the menu that opens from the top left.
- Menu > Tool > Primitive curves > Arc SED
Steps#
- Create an Arc SED node.
- Connect the start point of the arc to the first port.
- Connect the endpoint of the arc to the second port.
- Connect the direction (tangent) at the start to the third port.
After creating the node, connect the arc's start point to the first port, and the arc's endpoint to the second port, the direction (tangent) at the start to the third port. On the output ports, you will receive the resulting arc and its radius and plane.
