I need a full-stack web application that lets engineers upload an STP file of a machined component, optionally attach a PDF with specific tolerances, and receive an accurate manufacturing quote within minutes. The workflow should mirror the ease of use you see on Protolabs: drag-and-drop the file, pick a material, confirm tolerances, and instantly view price, lead time, and any manufacturability feedback. Core requirements • File handling: secure, fast upload of STEP (.stp) files; automatic extraction of basic geometry (volume, surface area, bounding box) for price calculations. A second channel must accept a PDF so tolerance notes can be linked to specific faces or dimensions. • Material coverage: the pricing engine must natively understand Metal, Plastic, Composite, Hard Metal, and Ceramic, with a structure flexible enough to add more grades later. • Pricing logic: combine geometric data, chosen material, and tolerance classes to produce a per-part cost, setup cost, and total quote. The model can be rules-based or ML-assisted, but results have to be returned in under two minutes. • User experience: clean, modern interface, mobile responsive, with an instant on-screen quote and a downloadable PDF summary. • Admin portal: manage material libraries, machining rates, margin multipliers, and monitor file conversions. • Technology: any robust stack is acceptable—common choices would be Python (FastAPI, Flask) or Node.js on the back end, React or Vue on the front—but the geometry crunching must rely on proven CAD kernels (e.g., Open Cascade, CGAL) to guarantee accuracy. Deliverables 1. Deployed website (cloud or VPS) with HTTPS and basic authentication 2. Source code repository with build instructions 3. AI / rules engine that outputs the quote JSON 4. Short video walk-through and written setup guide Acceptance criteria • A sample STP of a simple bracket uploads successfully and returns a price in <120 s. • Switching from Metal to Ceramic clearly updates cost and lead time. • Tolerance note in the accompanying PDF inflates price according to a rate I can edit in the admin panel. Hand-off is complete when the above acceptance tests pass on my server.

Hello, I am Muhammad Awais. I will deliver a robust full‑stack web app that lets engineers upload STEP files, optionally attach a PDF for tolerances, and view an accurate quote in minutes. My approach uses a secure two‑channel upload (STEP and PDF), automated geometry extraction (volume, surface area, bounding box) to feed a modular pricing engine, and a flexible material model that covers Metal, Plastic, Composite, Hard Metal, and Ceramic with room to add grades later. The pricing blends geometry, material, and tolerance bands into per‑part cost, setup, and total quote, with a fast, rules‑based or machine-learning informed engine returning results in under two minutes. The UI will be clean, responsive, drag‑and‑drop friendly, with instant on‑screen quotes and a downloadable PDF summary. An admin portal will manage material libraries, machining rates, margins, and conversions. Tech choices can be Python (FastAPI) or Node.js, React or Vue, and I’ll use a proven CAD kernel (Open Cascade or CGAL) to ensure accuracy. Deliverables: deployed site with HTTPS and basic auth, source repo with build steps, a rules engine that outputs the quote JSON, plus a short video walk‑through and setup guide. Acceptance tests: a simple bracket STP uploads and prices under 120 seconds; switching Metal to Ceramic updates cost and lead time; tolerance notes inflate price via admin adjustable rate. The project will be built with security, scalability, and clear error handling for a smooth UX. Do you p

Hi, this is Elias. I’ve reviewed your project and understand you’re building a full-stack web app that delivers instant manufacturing quotes from uploaded STP files, optionally paired with tolerance PDFs. With extensive experience in React/Node.js and Python-based backends, as well as CAD kernel integration (Open Cascade, CGAL), I can build a secure, responsive platform that handles geometry extraction, material selection, and tolerance-based pricing—all while keeping quotes under two minutes. I’d love to help bring this system to life. A few questions to clarify the workflow: Q1: Should the PDF tolerance notes be parsed automatically to link with specific faces/dimensions, or is a manual tagging interface acceptable for MVP? Q2: For the pricing engine, do you prefer a purely rules-based approach initially, or a hybrid ML-assisted model for more complex geometry? Q3: Are there target materials and grades pre-defined, or should the admin panel allow full flexibility for future expansion? Q4: Do you envision multi-part uploads (assemblies) at MVP, or only single-part STP files? Deliverables include deployed website with HTTPS, source repo, quote engine, admin portal, and video/written setup guide. Acceptance is based on correct STP upload, accurate pricing updates for materials and tolerances, and under-2-minute response. Looking forward to discussing timeline and tech choices. Regards, Elias

Hi A major challenge in instant manufacturing-quote platforms is extracting reliable geometry data from STEP files and translating it into consistent pricing without long processing delays. I build full-stack web applications that securely handle STP uploads, extract geometric metrics using proven CAD kernels like Open Cascade, and feed them into deterministic pricing engines. I would design a flexible pricing model that combines geometry, material classes, and tolerance rules while remaining editable through an admin portal. PDF tolerance attachments would be linked logically to parts so cost multipliers apply transparently and predictably. The frontend would deliver a clean, responsive Protolabs-style experience with instant quotes and downloadable PDF summaries. Backend services would be optimized to return results within strict time limits while remaining accurate and auditable. The outcome is a production-ready quoting system engineers can trust for fast, repeatable manufacturing decisions. Thanks, Hercules

Hi Alexandro, We’ve built similar platforms where users upload 3D files and receive instant quotes based on multiple factors. For example, we developed a solution for 3D printing companies that allowed users to upload STL files, select materials, and get instant prices. We also integrated a web-based 3D viewer to help users visualize their models before ordering. In your case, we can use a dedicated 3D file processing service to extract dimensions and surface areas from the uploaded files. This way, we can ensure that the file processing doesn’t slow down the main web app. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil

⭐⭐⭐⭐⭐ Hello Valuable Client, CnELIndia, led by Raman Ladhani, can deliver this quoting platform end to end by combining mechanical engineering depth with production-ready full-stack development. Our approach starts with a FastAPI backend using Open Cascade for STEP parsing to reliably extract volume, surface area, feature complexity, and bounding boxes within seconds. Secure drag-and-drop uploads will support both STP and PDF files, with PDF tolerance notes parsed and linked to features via a structured tolerance class system. This feeds a configurable pricing engine that blends rules-based logic with optional ML refinement to ensure quotes return well under your 120-second target. On the frontend, we build a clean, Protolabs-like React interface: material selection, tolerance confirmation, instant pricing, lead time display, and downloadable PDF quotes, fully mobile responsive. An admin portal allows you to manage materials (Metal, Plastic, Composite, Hard Metal, Ceramic), machining rates, tolerance multipliers, margins, and monitor CAD conversions in real time. Deployment includes HTTPS-secured cloud hosting, authentication, full source repository, JSON-based quoting engine, and a clear video and written handover. Raman’s mechanical engineering background ensures manufacturability feedback and cost logic reflect real shop practices, not just software assumptions—giving you fast, accurate, and scalable quoting from day one.
