As a user of AutoCAD 2015 I'm sure you'll agree with me that the software can really get under your skin! I was searching youtube for a detailed video relating to Mtext enhancements and stumbled across a genuinely helpful playlist. It includes tutorials and tips varying from design feeds to 3D Orbits. I'd really recommend you check this playlist out guys,  it has gave me some serious insight into areas that I once had little knowledge in!https://www.youtube.com/playlist?list=PLVigP9Yp6mnv0v1YAlxrthS2JZJ2RSc63
