I have a map terrain imported. I'm trying to extrude it along the z axis and then create a flat bottom for it. Usually I have no trouble doing this in blender. I select all the faces, extrude, then press s + z + 0 to flatten the bottom plane. However, in this terrain, when I try to extrude it will not extrude nicely along the z axis, instead it extrudes slightly off, and then when I apply my command it ends up slightly shifted. Object before extrusion Extrusion occurring, see that it is crooked I've now apply s + z + 0 and it is slightly tilted

  • $\begingroup$ Try extruding this way - select the vertices, Press E for extrude and without moving the mouse, hit a 'neutral' key. (esc?) That should release your mouse. Now drag the Z axis Gismo pointer down. (check your 'Transformation mode is set to 'Global') $\endgroup$

Try this:

  • Select all faces
  • Press E
  • Press ZZ (yes twice)
  • Drag along Z axis
  • S + Numpad 0 + Z

Without ZZ: Z axis is not straight

With ZZ after E: Z axis is straight

After selecting the Extrude tool (or pressing E), press X Y or Z to extrude along a specific axis. Press it twice XX YY or ZZ to extrude along the "global" axis.
