I made a height chart for myself, looks kind of like a police line-up chart. I only put a mark every 6 inches, which for me was good enough. I could modify this with more inch marks and share it on ShareCG, if anyone is interested???? Maybe even do a cm version for UK folks.
I just load it up as a prop and my figure loads perfectly in place. Then, choose the Front camera and you get a really good guide. Also helpful for viewing multiple characters, as you can see in my pic.
