Everyone occasionally runs into import/export issues when transferring files. Sometimes this can happen even when your "CAD friendly" format such as a step file. I can repair those files by repairing surfaces, recreating solids, creating assemblies from one imported part file, or whatever your needs may be. Contact me for a more in depth look at your unique problem and we will be happy to provide you with a quote. All files will be generated in SolidWorks format and will transferred to the customer along with all rights to the files upon receipt of payment.
