"3D Design and Modeling" You could omit the word "2D" and later use it on the job description. Puedes omitir la parte de '2D' y luego mencionarla en la descripción del trabajo. Por ejemplo. 3D Design and Modeling -Managing software such as SO and SO. -Able to draft 2D designs.....

I think it will be , Design and modification in 2D and 3D planes
