i selected edge using bounding box and i want to extrude the edge. but i can't get the perfect box or shape trying to switch different modes of polyextrude but still i can't get it done.
Hello, I don't really understand, you want to extrude them straight in the X or Z axis? I guess you can look at the “Extrusion Mode” and use custom normals to drive the extrusion (like 1,0,0 if you're extruding on the X axis)
