I am working on drawing a tool that has some pressed pins with a dome on the top and for some reason when I am trying to draw the dome, the follow me tool isn’t working right and its not finishing. Please see the attached picture. The way I did it was created the pin, and then drew an arc from one point of the circle on the top of the pin to the other side. I then drew a line on the blue axis from the center point of the top up to the arc and then from the center of the top to the side where the arc connects to the outside of the circle. I select the outer circle of the cylinder and click follow me and then click the face of the half arc and it does this. I opened a new window and was able to do it there but for some reason it wont work on this one. What am I doing wrong?
