Create Caps (polygon mode)
Enable this option to create a cap at the base of the extrusion. This gives you a quick way to create a
closed volume.
Edge Angle (edge mode)
Here you can set the angle of the edge extrusion. You can also change the extrusion angle interactively
in the viewport by holding down Shift during the extrusion.
Edge Snap, Value (edge mode)
If Edge Snap is enabled, the extrusion angle will be constrained to the Value setting. For example, to
constrain the extrusion angle to steps of 45 degrees, enable the option and set Value to 45°.
Preserve Groups
Preserve Groups enabled. Preserve Groups disabled.
If this option is enabled, the connected polygons will stay together during the extrusion, assuming
they do not exceed the Maximum Angle relative to one another.
To extrude along an object or world axis instead of along the normals, perform an extrusion with an
Offset (i.e. extrusion length) value of 0; then move the new surfaces using Move:
To extrude, say, in the Z direction, lock the X and Y axes:
