I can model your 2d library elements or design into Revit parametric or not parametric families according to requirements with a varying degree of detail.
The deliverable files:

·        The source file RVT Family with the appropriate version
·        3D DWG version
·        description of parameters and their roles

What I need to work properly:
Your DWG files with annotations (plans, elevations, sections of the object)
Technical documents of the element
The version needed of the output model

For an extra, the family can be created with another 3D software in a highly polygonal model dedicated principally to rendering and 3D visualization.
