Drawing/sketches in blender I'm pretty new to 3d modelling and have been working through a lot of tutorials. Something I see come up often is users importing sketches of objects such as people, the then seem to create the model around these front, top and side view sketches. 

Would anyone be able to link me to a tutorial explaining this feature and its benfits, tricks, how to do it properly?

Sorry if this thread already exists. I couldn't find one

Thanks
You could follow this

It seems suited to a beginner, to me.

My personal advice: the most precise (all views well aligned, same scale, absolutely still subject) front/side/top view you can get, the better.
