Convert to CAD for fabrication

Hey - I need to convert my SketchUp Design to CAD format/2d/3d drawings that show dimensions etc so that it can be pre fabricated and cut. I also still need to add where the dowel holes/joinery onto the design and drawings so they can be machine drilled as well for how it will all come together. I am past my experience level with the program to do it/ my wood working knowledge as to what i need to do to make it structurally sound.
I will also need advice on the legs mechanically as it will be a sit/stand desk and how I connect the two electric telescopic lifting column with linear actuators or if there is a better option for what I'm trying to achieve
