Reverse Engineering Services: What to Send Before Requesting a Quote
To get a fast, accurate reverse engineering quote, send five things up front: photos of the part from several angles, its rough size and weight, the file you actually need back (STEP, a mesh, or 2D drawings), the tolerance the model has to hold, and whether the object can ship to us or has to be scanned where it sits. Those five inputs decide almost everything about scope and price. A loose reference model and a tight scan-to-CAD reconstruction for fabrication are completely different jobs, and “can you reverse engineer this?” does not tell us which one you are buying.
The rest of this page is what each of those inputs changes, and why a clear request comes back as a real number instead of a range with caveats.
Start with the file you need back, not the part
The single biggest scope driver is the target output, because reverse engineering is not one deliverable. The same scan can become a watertight mesh (STL, OBJ, PLY) for visualization or 3D printing, a parametric solid (STEP, IGES, or native CAD) for design and manufacturing, or a 2D drawing set (DWG, DXF, PDF) when your team only needs dimensions and profiles. Each path costs differently because the work after capture is different. A mesh is close to the raw scan. A clean parametric solid means a modeler rebuilds the part feature by feature, deciding which faces are true planes, which holes are nominal, and where a worn edge should be idealized.
So tell us the destination. “We need a STEP file a machine shop can quote from” and “we need a reference model to check clearance in an assembly” send the job down two different workflows. If a vendor, engineer, or shop will receive the file, ask them which format they want before you order the work; rework after delivery is the most avoidable cost in this whole process. Our reverse engineering services page covers the output paths in more detail, and 3D Scanning Reverse Engineering: CAD, Mesh, or Drawings? walks through how to choose.
Photos and rough dimensions: how we scope before we touch the part
Photos let us estimate capture and modeling effort before anyone sees the object in person. Shoot the front, back, both sides, top, and underside if you can reach it, plus close-ups of anything that drives the model: holes, slots, threads, fillets, complex edges, and any wear, cracks, or repaired areas. Put a ruler or a known object in frame for scale. They do not need to be pretty. They need to show geometry, access, and condition.
Rough dimensions matter just as much, because size changes the capture method. A small machined part that fits on a table is a candidate for our handheld Creaform MetraSCAN 3D, an optical metrology scanner built for tight tolerances, where the result is a high-density, metrology-grade mesh of the part. A large installed component, a tank, a weldment, a duct run, or anything bolted into a building is field work for a terrestrial laser scanner like our Trimble X7, where the value is capturing the part and the surrounding geometry it has to fit into. Send overall length, width, height, approximate weight, largest diameter if it is round, and whether moving it needs a lift or special handling. That one detail often decides whether the job is an afternoon or a multi-day field effort.
Tolerance: say what the model has to do, not “as accurate as possible”
Tolerance is the input people most often skip, and it is the one that moves the estimate the most. “As accurate as possible” is not a spec; it pushes every surface toward the tightest interpretation and prices accordingly. Instead, tell us what the deliverable has to accomplish. A model for visual reference or rough layout can tolerate millimeter-level deviation on most faces. A replacement cover that has to seat in an existing bore needs tight control on the mating features and can be loose everywhere else. Inspection or first-article comparison may need a documented accuracy statement tied to the scan hardware.
Wording like “we need profiles for a replacement gasket cover,” “we need CAD geometry to compare against a worn part,” or “we need drawings for documentation, not a manufacturing release” lets us match effort to the features that matter and leave the rest reasonable. It is also worth deciding, up front, whether you want the part’s current measured condition, its original design intent, or a clean practical replacement geometry. A worn, repaired, or modified part diverges from its drawing, and that fork is a scope decision, not a detail to settle in review.
Ship it or scan it on site
Reverse engineering can run from an object shipped to us or from a scan in the field. Which one fits depends on the part and your operation, not on preference.
| Ship the object | Scan on site |
|---|---|
| Small enough to crate and move safely | Installed, bolted in, or part of a larger system |
| Removal will not damage it or void anything | Too large or too heavy to ship |
| You want all-sides access in a controlled bay | Removal risks damage or unacceptable downtime |
| Timeline allows transit both ways | Surrounding geometry and clearances matter |
| Best fit for small, precise parts | Best fit for large or facility-tied components |
If the work has to happen on site, that changes logistics and price more than the modeling does. Send the location, site access and check-in rules, safety requirements, and the hours we are allowed to work. Occupied or after-hours access raises labor cost, and a part you cannot reach from all sides may need disassembly or a return visit. When the component is tied into a building, this overlaps with our 3D laser scanning services, and the laser scanning site prep checklist covers what to line up before the crew arrives.
Surface and material change the capture, not just the price
The surface affects what a scanner can see. Shiny, black, transparent, or oily surfaces scatter or absorb the laser and may need a temporary matting spray or a different capture strategy. Flexible parts can move during capture and need fixturing. Painted, corroded, or partially missing surfaces blur the line between what the part is and what it was designed to be. Tell us about these conditions in advance so we plan the right approach rather than discovering it on the clock.
Where reverse engineering stops
It helps both sides to be clear about what a documentation deliverable does not include. Producing geometry, a CAD model from scan data, or a drawing set is not the same as engineering responsibility. Reverse engineering as we deliver it does not carry an engineer’s stamp, structural calculations, material testing, failure analysis, product certification, code compliance, or final design ownership. If you need any of those, name them as a separate line so the right licensed professional can be brought in. Confusing as-is documentation with redesign is the most common source of bad expectations; Reverse Engineering Scan-to-CAD vs Product Design pulls those two apart in detail.
A quote moves faster when these are answered
Estimates stall on open questions: no photos, no rough size, an undefined output format, no tolerance, unclear site access, or no sense of how the file will be used. You do not have to solve the engineering before you ask. You only have to give us enough to separate a quick scan-and-drawing job from a detailed CAD reconstruction. If you can answer the five inputs at the top of this page plus your deadline, request a quote and we can usually scope it without a second round of questions.
FAQ
What is reverse engineering?
Reverse engineering is the process of capturing an existing physical object, usually by 3D scanning, and turning that measured geometry into a digital model or drawing set. It documents what a part actually is so you can recreate, replace, inspect, or design around it.
Is reverse engineering legal?
Reverse engineering a part you own, for repair, replacement, interoperability, or documentation, is generally legal in the US. It can run into trouble where patents, copyrighted design files, or contractual or trade-secret restrictions apply. We document geometry; we do not provide legal or patent analysis, so confirm rights with counsel before reproducing a protected design.
How does 3D laser scanning work for reverse engineering?
A scanner sweeps the object with a laser or structured light and records millions of surface points as a point cloud. We register and clean that data, then either deliver it as a mesh or rebuild it into a parametric CAD model. Large or installed components are captured on site with a terrestrial scanner like the Trimble X7; small precision parts are captured with a handheld optical metrology scanner like the Creaform MetraSCAN 3D, which is built for tight tolerances.
What is point cloud to CAD conversion?
It is the step where a modeler turns the raw scan points into usable CAD: fitting planes, cylinders, holes, and edges into clean surfaces or solids rather than leaving a dense, unstructured mesh. The output is a STEP, IGES, DWG, or native CAD file your team can actually edit and build from.
How much do reverse engineering services cost?
There is no neutral per-part benchmark; price tracks the target output and tolerance, not the size of the object. Field scanning is typically billed by the day or hour, while CAD reconstruction is priced by part complexity and the accuracy it has to hold. A loose reference mesh and a tight, fabrication-ready solid of the same part can differ by an order of magnitude, which is exactly why the inputs above matter.
