When you are modelling, it’s easy to extract a piece of mesh from an object, but how do you do it when you simply want to copy and paste a section of the mesh as a new object.

4. Select the end of the vertex and extrude the path by pressing E. (Go to the top or side view to keep the extrusion to conform to a single axis.)

5. In the Curve panel, adjust the Extrude field to scale the height of the mesh.

6. Go back to the Depth and change the value to 0 to create a ribbon like surface.
