the tools I learned to use

I only learned two tools. I learned how to but the shield in my helmet. I had to go to edit mesh, then to append to Polygon tool. The other tool I learned was to but points to smooth the shield on my helmet. To do that i had to go to edit mesh. Then I click on Split Polygon Tool. I put two points on the side view. I then the two points made a line. From the perspective view it made three points. I just moved the three points to make the shield smooth
