AI is Adobe Illustrator. Again, the extension name, so clear if you know it already. 

Things you might need to make Illustrator work better, and which I could not easily find. Some are probably version specific. 

 * Perspective-like distorting involves using modifier keys at specific times:
  1. Select whole shape, groups work fine.
  1. E (free transform)
  1. Start dragging a “downrange” corner
  1. Click Cmd to convert that corner only
  1. Click Cmd+Shift+Opt to move it and the corresponding pont with axial symmetry.
  1. Be sure to shorten also. I'd distort a square as your guide before doing any actual work, and keep both a distorted and original shape as your guide.
