yes you can. but I'm not sure what format you are referring to as a "cut file". I think a big reason you don't see them is a lot of the DIY community here is not using cnc for their builds and that there are a ton of Cad programs out there so a lot of variety in file types.
The normal file type we use for transfer is Autocad dgn or dxf for 2d and OBJ or STL for 3d formats. These can be easily imported by the cad drawer and then they can run their cnc code generation/pathing tools/machine post-processor to get the gcode to use with their specific machine. That cut file generated by the post-processor would then only be good with that exact machine without someone making changes to formatting/M and G code usage and some of the tool management features a post processor does for the individual machine and controller type. Depending on how many lines of code that is, it could be a massive PITA. I have hand edited cnc plenty of times though.
There is a ton of variety in cad and cnc software out there. Just for me, the different software I use for programming: Autocad, Solidworks, Rhino 4.0/cam, Vectric, Procad, and I'm in the process of learning Mastercam.
Summary: 2d I prefer to import dxf or dgn files. 3d: prefer obj or stl files. Sketchup stuff can be modified for use usually without a ton of effort
