Hey guys, I found a really cool model I wanted to play around with ( https://grabcad.com/library/vertical-screw-shipunloader-1 ) but when I try and import the STL file it says It's too large and turns it to a graphic. (which can't be moved or modified in any way)

I know you can go to Insert > features > convert to mesh body, but having to click every single face is really tedious and causing everything to lag out.

Is there any way someone can help me get this file as an editable part? I was primarily hoping to be able to scale the part and mate it to other surfaces.
