How do you put sketch in background?
 

HELP!!!!
Hey how do i put sketch in the background or on a plane to model off of?

In one of your vieports.. " Front side, top, just depending on what angle the reference image is.... Click View > Image Plane > import image... then find what ever it is your looking for

thanks a bunch

You can also make an object (a plane) with the dimensions equal to your image.. and put a texture on it with your image. This usually gives alot faster viewport updates, and you can move the image around.
