CAD File Privacy, Confidentiality & NDA Requests

This page explains how project files and contact information are handled when you contact SPI for quotation or engineering review, including CAD drawings, revision data, RFQ details, and confidentiality requests.

  • CAD & drawing confidentiality
  • NDA requests before file sharing
  • RFQ and contact data handling

If your company requires an NDA before sharing confidential files, contact SPI before upload so the request can be reviewed and arranged before project documents are submitted.

Contact SPI Before Sharing Files

RFQ & Project Information

What Information May Be Included in an RFQ?

An RFQ may contain technical files, contact details, and project requirements needed to evaluate the request and communicate about the manufacturing project.

Technical Files

CAD models, drawings, revision information, material or resin requirements, surface-finish requirements, and critical dimensions or tolerances.

Contact Information

Name, company, business email, phone number, and other contact information provided for quotation or project communication.

Project Requirements

Quantity, requested timing, packaging or labeling needs, documentation requirements, and relevant prototype, tooling, or revision background.

The information supports quotation review and project communication. Technical evaluation details are covered separately in Pre-Quote DFM Review .

CAD & Drawing Confidentiality

How CAD Files, Drawings and Revisions Are Handled

Technical files should remain tied to the specific quotation or manufacturing project they support. Clear revision identification also helps prevent outdated drawings or specifications from being used during later project stages.

  • Project-Specific File Use

    CAD models, drawings, specifications, and related project documents may support quotation review, feasibility discussion, production planning, inspection communication, and other work connected to the submitted project.

  • Drawing and Revision Clarity

    When a drawing, CAD model, or specification is revised, the current revision should be clearly identified so superseded information can be distinguished from the latest project requirements.

  • Confidentiality Requirements

    If your organization has project-specific confidentiality instructions, include them before or when the technical files are submitted for review.

Access & Project Handling

Who May Handle Project Files and Information

Project information may need to be reviewed by different functions during quotation and manufacturing. Access should remain connected to the work required for the specific project.

Internal Project Access

CAD files, drawings, and RFQ information may be reviewed by personnel involved in quotation, engineering, production planning, quality, or project coordination when those functions are relevant to the work.

External Project Support

If outside processing or project support is required, only information relevant to that activity should be shared, subject to the confidentiality terms and project instructions that apply.

Purpose Boundary

Project information should remain tied to quotation, engineering review, production, inspection, documentation, or other activities needed to execute the submitted project.

Customer-specific confidentiality requirements should be identified early. They can then be reflected in the applicable NDA or project instructions.

Retention & Privacy Requests

How Long Project Information Is Kept and How to Request Changes

Project and contact information may be retained for quotation, manufacturing, quality, communication, recordkeeping, or other legitimate business needs connected to the project.

Retention Period

Retention may vary according to project status, contractual requirements, recordkeeping needs, and applicable legal or business obligations. This page does not state a fixed retention period where one has not been formally defined.

Correction or Deletion Requests

Customers may contact SPI to ask about correcting contact information or requesting deletion of data that is no longer required. A request may need to be verified before action is taken.

Records That May Need to Remain

Some quotation, transaction, quality, contractual, or project records may need to be retained where required for ongoing work, legitimate recordkeeping, or applicable legal obligations.

For a privacy or file-handling request, provide enough project or contact information for the request to be identified and send it through Contact Us .

Privacy & Confidentiality Support

Questions Before Sharing CAD Files or Project Information?

Contact SPI if you need to clarify file handling, request an NDA before submission, ask about retained project information, or discuss a confidentiality requirement before sending drawings or RFQ documents.
