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
