To extrude edges or faces along a path curve Select the edges/or faces you want to extrude and the curve you want to extrude along. Select Edit Mesh > Extrude > . Turn on either the Selected or Generated options. Click Extrude. Use the controls in the Attribute Editor or Channel Box to edit the extrusion. For example, increase Divisions so the extruded polygons better match the shape of the curve. Reduce Taper so the extruded polygons gradually become narrower along the curve
