My car's topology is messing up as soon as I attempt to move a group of vertices along the y-axis I am modelling a car and am using edit mode to position the trunk. Whenever I move my string of vertices along the y-axis, the topology gets really strange, and it looks like one of the edges (with one of its vertices selected), is not being affected by the movement of that vertex. I do not know why this is happening. I removed the only modifier (mirror) I had on the car, and tried removing doubles. It told me it "Removed 0 vertices", and the problem is still there. Please help me!
Okay, I fixed it. I had to delete most of the vertices in the middle of the car and then fill in the edges and faces. It was tedious, but I did not know any better way. The only question I have now is will using the loop cut/slide tool cause bad topology again? That is what I used and it messed up my topology, so I am wondering whether or not I should continue using that tool or if there is a better way of adding more vertices. Thanks for your help!
