Hey! Many (maybe most) of us have ability to use CAD files and explore/experiment with your models without the drawing packages. As a humble recommendation, then, I would suggest that you make the CAD models available as early as you can and welcome derivative contributions from fellow designers/builders. My belief is that that would not only accelerate the project but it would also result in the weeding out of problems before you invest a whole lot of time in putting together the drawings.
