Hi .... I have a multi-part assembly made mainly from complex injection molded type parts that I am looking at combineing together and makeing one solid model from. The model will be exported in .step format so that some packageing can be designed for the product. Is there an easy way to do this? When I JOIN the parts together I can get a multi-body assembly but can't seem to get any further by combineing the bodies together without getting an error. The main reason for joining the parts together is to make it harder for anybody to reverse engineer the product parts and to keep the final solid model as simple as possible while still maintaing the external profile.

Any help would be appreciated.

Thanks
