NestLib® does not support any file formats. You use the NestLib® API’s to input the part or sheet geometry. As long as the application can read the file and call the API’s, you can integrate NestLib with any file format. For e.g. the NestLib® evaluation version read DXF files. This is because GEOMETRIC has implemented a DXF reader in the evaluation version, which reads the DXF files and calls the NestLib geometry input API’s.
