Depending on the complexity and completeness of the sketch, creating a drawing might only take a few hours. If the sketch is more of a concept that needs some refinement, it will take a couple days, but I am happy to help with making sure the final print aligns with your design intent. I have experience in using GD&T on engineering drawings to ensure functionality and reduce costs, and in the product development process, including design and manufacturing.
I currently use a program called OnShape to create parametric CAD models and engineering drawings. Drawings can be exported in all the major file formats, including PDF, DXF, and DWG. I can also provide you with a 3D solid model of the part(s), as well. Many machine shops and fabricators now request a solid model before beginning work.
Please feel free to contact me with any questions or comments.
Thank you,
Andrea Grisell
