I do almost all kinds 2D of 3D CAD drawings. I specialize in Mechanical components and equipment though. I can also do Finite Element Analysis for mechanical and thermal performance and flow modeling...
I would usually need a fully dimensioned sketch and details of your drawings with any other requirements. However I can also advise on geometry and dimensions if you don't have it fully conceptualized yet. I can also offer product design consulting, advice and reviews.
You may need to purchase gig extras or multiples depending on the complexity of the drawings; this would be mutually determined and fair to both of us.
Please discuss requirements and details before ordering. Look forward to working with you! Cheers
