Pre-Tooling CAD Risk Audit

Get your CAD reviewed before you send it to suppliers, fabricators, mold makers, or tooling partners.


A fixed-fee CAD and manufacturing risk audit for product teams who want to identify practical design, manufacturability, assembly, and supplier quote risks before committing to tooling or production.


Pre-Tooling CAD Risk Audit — $950

Suitable for up to 3 parts or 1 small assembly.

CAD Risk Audit by Ben Nel, BSc Mechanical, founder of 3DDFM, with nearly 30 years of practical product design, CAD, tooling, and manufacturing experience.

  • Upwork Top Rated Plus

  • International clients

  • Injection molding, sheet metal, enclosures, prototyping, and manufacturing background

  • Practical DFM experience, not theoretical review only

Intro

Sending CAD to suppliers too early can create expensive problems.

A supplier may quote around incomplete information, miss important design risks, or come back later with changes that affect cost, tooling, lead time, or product performance.

The Pre-Tooling CAD Risk Audit is designed to give you an independent technical review before you commit to supplier quotes, tooling, fabrication, or production planning.

The goal is simple:

Identify the major CAD and manufacturing risks early enough to make better decisions.

This audit can help identify risks such as:

  • CAD that looks finished but is not ready for manufacturing.

  • Features that may increase tooling or fabrication cost.

  • Missing or unclear information for supplier quotes.

  • Process mismatch between design intent and manufacturing method.

  • Part geometry that may be difficult, expensive, or unreliable to manufacture.

  • Assembly issues that are not obvious from individual part models.

  • Unclear material, tolerance, or production assumptions.

  • Supplier quote risk caused by incomplete or risky design information.

  • Early design decisions that may become expensive to fix later.

What we review:

  • Overall CAD readiness

  • Manufacturability risks

  • Process suitability

  • Part complexity

  • Assembly risk

  • Supplier quote readiness

  • Critical features that may affect cost or production

  • Obvious tolerance or fit concerns

  • Material and process assumptions

  • Areas that may need redesign before tooling or supplier quotes

  • Recommended next steps

Manufacturing processes this can support:

This audit can be useful before several manufacturing routes, including:

  • Injection molding

  • Sheet metal fabrication

  • CNC machining

  • 3D printing for prototype or production use

  • Fabricated assemblies

  • Electronic enclosures

  • Mixed-process mechanical products

  • Small mechanical assemblies

If your project is clearly injection molded and you need a deeper plastic part review, the Injection Molding DFM Review may be a better fit.

If you are unsure which review you need, submit a Project Review Request.

What is included:

  • Review of up to 3 parts or 1 small assembly

  • Review of supplied CAD files, drawings, screenshots, photos, or supplier feedback

  • High-level manufacturing and CAD risk assessment

  • Review of supplier quote readiness

  • Identification of practical design risks before tooling or fabrication

  • Priority list of concerns

  • Recommended next steps

  • Written summary report

  • Annotated screenshots where useful

The audit is intended to help you understand what may need to be fixed, clarified, simplified, or checked before moving further into manufacturing.

What is not included:

  • Full CAD redesign

  • Detailed engineering redesign

  • Mold design

  • Tooling design

  • Supplier sourcing

  • Manufacturing management

  • Full detailed DFM report for every feature

  • Production-ready drawings

  • Tolerance stack analysis

  • Simulation or FEA

  • Costed manufacturing quote

  • Unlimited revisions

  • Multiple design iterations

If deeper design work, supplier sourcing, or a detailed DFM review is required, we can recommend the best next step after the audit.

Standard audit scope:

The fixed-fee Pre-Tooling CAD Risk Audit is suitable for:

  • Up to 3 parts, or

  • 1 small assembly

For complex assemblies, multi-process products, mechanisms, electronics-heavy products, or projects with more than 3 parts, please request a Project Review before ordering.

This helps us confirm the correct scope and avoid under-quoting or over-promising.

To get the most value from the audit, please prepare any relevant information you have:

  • STEP files or CAD screenshots

  • 2D drawings if available

  • Assembly screenshots if relevant

  • Product photos or prototype photos

  • Supplier feedback if available

  • Target manufacturing process

  • Expected production volume

  • Target material if known

  • Main concerns or questions

  • Current project stage

  • Any known constraints, such as cost, size, material, or assembly requirements

You do not need to have everything finalized, but the more information you provide, the more useful the audit will be.

How it works:

  1. Order the Pre-Tooling CAD Risk Audit.

  2. Submit your CAD files, screenshots, drawings, product details, and main concerns.

  3. We review the information against likely manufacturing and supplier quote risks.

  4. You receive a written summary report with priority risks and recommended next steps.

  5. If needed, we recommend whether the next step should be redesign, a deeper DFM review, supplier quote preparation, or a strategy call.

The purpose is to give you practical direction before you spend more money on suppliers, tooling, fabrication, or production.

Frequently Asked Questions

Is this a full DFM review?

No. This is a focused CAD and manufacturing risk audit before tooling, fabrication, supplier quotes, or production planning. It identifies practical risks and recommended next steps, but it is not a full redesign or detailed process-specific DFM report.

How is this different from the Injection Molding DFM Review?

The Injection Molding DFM Review is focused specifically on plastic parts intended for injection molding. The Pre-Tooling CAD Risk Audit is broader and is useful when the manufacturing process is not fully confirmed, when the product uses multiple processes, or when you need an early supplier-readiness check.

How many parts are included?

The standard audit includes up to 3 parts or 1 small assembly. Larger assemblies, mechanisms, electronics-heavy products, or products with more than 3 parts may require a custom quote.

Can I send assembly files?

Yes, if the project fits the standard scope. For larger assemblies or complex products, please submit a Project Review Request before ordering.

Will you redesign my CAD?

No. CAD redesign is not included. If redesign is needed, the audit will identify the issue and recommend the next step.

Will I receive a written report?

Yes. You will receive a written summary report with priority risks, comments, and recommended next steps. Annotated screenshots may be included where useful.

Can this help before I ask suppliers for quotes?

Yes. That is one of the main purposes of this audit. It helps identify missing information, design risks, or manufacturability concerns before you send files to suppliers.

Can you review supplier feedback?

Yes. If you have supplier feedback, you can include it with your submission. We can review it as part of the audit and help identify what needs attention.

Does this include supplier sourcing?

No. Supplier sourcing is not included. If you need help preparing supplier quote information or sourcing manufacturers, that would be quoted separately.

What if I am not sure which review I need?

Submit a Project Review Request and we will recommend the most suitable paid option.

Make a Better Manufacturing Decision Before Spending More Money

Check Your CAD Before You Commit to Tooling or Supplier Quotes

A small design risk can become expensive once suppliers, tooling, or production are involved.
