Our Services

There are three different techniques to convert a 3D scan (STL) into CAD format (STEP). The geometry of the part and the final application decide which technique is best suited for your project. We have created a video for each process and written a detailed article describing the pros and cons.

Reverse Engineering to surface model

A striped pattern is projected onto the object. Stereo cameras determine the surface geometry from the reflection.

Reverse Engineering to solid model

Converting a 3D scan as accurately as possible into a CAD solid model. This technique is for objects with simple geometries.

Reverse Engineering to parametric model with a history tree

This technique allows us to convert a 3D scan into the native CAD format or whatever CAD software our client is using.

We would be happy to advise you on which 3D scanning technique is best suited for your project.

How we convert a 3D scan to CAD?

What is Reverse Engineering?

With reverse engineering we can convert a 3D scan into a CAD format. STL to STEP conversion is an example of reverse engineering.

Either you can provide us with 3D data to reverse engineer or you can provide us with a mechanical part to 3D scan ourselves. Once we have a 3D scan to work with, we can use special software to reverse engineer the part. Finally, we provide you with the CAD data to download so that you have all the information you need.

How much
is a 3D Scan?

In 3D-scanning, the rule of thumb is: “The more accurate the 3D scan, the more expensive.” Holocreators offers 3D-scanning for simple objects starting at 95 EUR.

In what file format we providing the completed files?

Depending on the selected reverse engineering procedure, we can provide your data in the neutral CAD exchange formats STEP, IGES, X_T, or in the native CAD format of the specific CAD software you personally use.

Reverse engineering to surface model

With the reverse engineering to surface model, we can convert a 3D scan into a CAD surface model.

This technique for reverse engineering is particularly suitable for organically shaped parts with curved surfaces. The aim is to keep the deviations between your 3D scan and your surface model as small as possible. Manufacturing defects of the original 3D-scanned part are transferred to the reverse engineered surface model, because an error correction would be at the expense of the reconstruction accuracy.

Reverse engineering to solid model

Reverse engineering to solid model allows the conversion of a 3D scan (STL) into a CAD solid model (STEP). The goal is to keep the deviations between the 3D scan and solid model as small as possible. There is no correction of manufacturing defects of the 3D scanned part so that accuracy can be maintained. The resulting solid model can consist of simple geometries or complex NURBs surfaces. When simple geometry and NURBS are combined in one model, it’s sometimes called a “hybrid”.

Reverse engineering to parametric model witha historytree

Reverse engineering to parametric modeling with a history tree involves converting a 3D scan into your native CAD format. The finished CAD model thus contains a history tree, and you can adjust all parameters yourself in your own CAD program. A technical drawing can be derived from the parametric CAD model with little effort.
