Is there a way to prevent STL file resize?

Is there a way to import an STL file without the dimensions changing based on the material size?

Details: I have an STL of a guitar body, which has critical dimensions. For example, the neck pocket must be a specific width and depth so that the neck can be attached to the body and fit properly. So far, I have not been able to accomplish this because Easel resizes the STL (and therefore the neck pocket dimensions) based on the size of the material. Is there a checkbox in a menu somewhere that I’m missing?

I can’t answer that but in regular easel you click on the object, hold down the shift key and move the size in both directions at the same time. By the way there is a tele body in the luthier section here.
