Hi Arezoo,
Could you share a screenshot of the parameters you are using to define your Biconic surfaces? There could be a number of issues in the definition, and it would be easier to understand if I can try to replicate your surfaces.
You may be unable to create a proper archive file since there is an error present in your model. Let me know if you continue to get errors regarding archive file creation, once you create a working model.
