Hello, I'm William.
Previously, I worked in a toy company which has a lot of PVC figures with much sculpture details or organic shapes, and I had good experience to convert 3D models in ply/stl/obj format to stp or igs format so that they can be further edited by other 3D CAD programs like Pro/E, Solidworks, UG, etc, then for further CNC machining and mold making.
For this project, I will use the most advanced technology of reverse engineering provided by Geomagic to do the conversion of 3D model format. I can provide you with both stp and igs format if necessary, and also report of 3D deviation about conversion, i.e. showing comparison between original data and data after conversion.
You may take a look at some examples shown on my portfolio and understand what I can provide to you.
Thank you for your kind attention!
