  • 3D STEP/STL viewer in the browser
    Open and inspect 3D CAD files directly in your browser. No CAD license, no plugins, no desktop software required. Works on Mobile as well.
  • Pin comments directly on 3D model
    Click any point on a 3D model to pin a comment with exact visual context. No more describing "the corner on the left side."
  • PDF and image review
    Review technical drawings, schematics and images with markup tools, distance and angle measurements โ€” all in the browser.
  • Share review links
    Send a link to anyone - suppliers, clients, teammates. They can view and comment without creating an account or paying for a seat.
  • Issue tracking with severity
    Assign severity levels, set deadlines, track resolution status. Every comment becomes a trackable issue.
  • Export review as PDF
    Generate a PDF report with all comments pinned on the model or drawing. Ready to share with stakeholders or archive.
  • Wire tracing on PDF
    Click a line on an electrical schematic โ€” the system highlights the entire connected circuit through connectors and branches. One click instead of tracing by eye.

    While suitable for beginners, the book doesnโ€™t delve deeply into advanced features of Python, which might leave learners needing additional resources for more complex topics.
  • Pacing
    Some readers might find the pacing of the book too slow, particularly if they have some prior programming experience, as it aims to accommodate complete beginners.
  • Lack of Exercises
    There are fewer exercises compared to some other programming books, potentially providing less practice for readers to reinforce their learning.

Questions & Answers

As answered by people managing Revievv and Think Python.

What makes your product unique?

Revievv's answer

Reviewers don't need a CAD license, an account, or any installed software. Just a link. Most design review tools charge per seat or require everyone to have CAD software. Revievv gives unlimited free reviewers on every plan - so your suppliers, clients and cross-functional teammates can give feedback without any barriers.

Why should a person choose your product over its competitors?

Revievv's answer

Some competitors costs six figures and takes months to deploy. Revievv starts at $0, works in 30 seconds, and does what engineering teams actually need: open a CAD file, pin comments on the 3D model, share a link, collect feedback. No procurement process, no IT department required.

How would you describe the primary audience of your product?

Revievv's answer

Mechanical and electrical engineers in teams of 5-50 people โ€” product design, manufacturing, automotive, aerospace. Engineers who send STEP files by email, mark up screenshots in PowerPoint, and lose feedback in chat threads. Also useful for engineering managers who need documented, traceable design reviews instead of meeting notes in Excel.

What's the story behind your product?

Revievv's answer

Built by an engineer with ADHD who got tired of the same broken design review process, also had problems with doing all those related topics โ€” screenshots in PowerPoint, feedback lost in email threads, "see attachment page 3 top left corner." Every CAD collaboration tool was either enterprise-priced or view-only. Revievv fills the gap: real design review with 3D markup, simple enough to start in 30 seconds, affordable enough for a small team.

Which are the primary technologies used for building your product?

Revievv's answer

Three.js for 3D rendering, OpenCascade for STEP/STL geometry processing, Next.js for the web application, and cloud infrastructure for file conversion. Everything runs in the browser โ€” no plugins or desktop installation needed.

Who are some of the biggest customers of your product?

Revievv's answer

Revievv is an early-stage product used by small and mid-size engineering teams. We're focused on onboarding our first 100 customers โ€” teams that need fast, affordable design review without enterprise overhead.
