Extrude pulls a selected face, edge or vertex outward and fills the gap with new geometry joined to the old.
Drag a model to turn it.
Extrude a faceThe top face moves out along its normal, and a new side face fills each of its edges.Extrude, scale, repeatExtrude the top, shrink the new face a little, extrude again. Four rounds make this tower.Extrude sidewaysAny face can be extruded. Extrude a side face, then the top of the new part, and an arm grows.Extrude an edgeAn extruded edge makes a new face. Good for fins, flanges and building walls from a floor outline.Extrude a vertexAn extruded vertex makes a new edge. Chains of them trace wires and branches.
