Blender can't get extrude to lock in odd position again So I was making a side walk for a curved park of a road that I made, but I wasn't sure how I was going to make it. when I tried to extruded the edge, the extruder locked into place in some odd angle, but it was an angle that surprisingly worked perfectly for me so I got the side walk on on side of the road but on the other side I couldn't figure out how to get the extruder to lock into place. I will include a picture to help show my problem. I would really like if someone could point out how I made the extruder lock into place like in a odd angle.

Thanks, Nova
By default extrude will lock along the normal of the selected faces. The normal is perpendicular to the plane of the face. In other words, the direction the face is facing.

To unlock it, press Z after extruding.

To re-lock it, set the transform orientation to normal in the header of the 3D view. Then press ZZ after extruding and unlocking (or GZZ if you cancelled/completed the extrude/transform operator)
