CNC machining of plastic

[John_H555]

There is a service at

www.firstcut.com

that will machine parts from plastic using CNC.  The company is part of ProtoMold.

They will quote in a day, nominally, but they seem to be most at home in Solidworks. 

I sent them a component in a ACIS file (suffix is .sat) exported from a Rhino 3dm file. 

They reported back that it is an "assembly" of parts.  In fact it is one single part, but it is made up of several objects. 

Has anyone encounterd this?  In other words: How would I make my "assembly" look like one part -- which it is -- to their system?

Or.  Is there a CNC vendor that knows Rhino and works from Rhino files directly? I really like the idea of working with machined parts.

Many thanks for your insights.

Each piece of the model must to be 1 file. In solidworks you model each part and them create a file to assembly them. So, to you print multiple pieces you need to create multiple files and send them. Or you can just ask them how they want the file and explain is not solid format.
