Like the title stated, I am hoping someone can help me by converting a file format. I had someone design an object for me but they provided the file as a .3dm and I cannot open it or upload it to Shapeways in that format. I already asked him to convert it but am not getting a response. If someone could change a .3dm to a .obj for me I would appreciate it. I believe their are converters I could download myself, but I am on a university computer and cannot download any programs. I am attaching the file. Thank you!
