Reverse Engineering from STL to STEP
Reverse engineering is the manual reconstruction and the creation of CAD data based on the existing points of a 3D scan. We create CAD data that is used in toolmaking, 3D printing, and e.g. are also very valuable for FEM calculations or other simulations.
What is Reverse Engineering?
Reverse Engineering refers to the process of re-creating design drawings by taking measurements and/or scans of the part itself. It’s a simple, two-step process: 1) scan the object, 2) create a 3D model of the object.
In mechanical engineering, the term reverse engineering (often abbreviated to RE) is used to summarise the process of reconstructing an existing object. With reverse engineering, the design engineer starts with the final product and works through the design process in the opposite direction to arrive at the product design specification.
The process of reverse engineering begins by gaining three dimensional information of the object via 3D scanning, whether it is a mechanical component or a consumer product. Reverse engineering involves acquiring three-dimensional positional data in the point cloud.

What is the difference between Reverse Engineering CAD data and 3D Scanned 'Raw' data?

Scan-based files involve cleaning up the scan, optimizing the mesh quality, and ensuring that the scanned mesh is watertight. At this point we can generate the neutral file based on this processed scan data. CAD-based is bit more labor intensive. It involves interrogating the mesh, creating CAD sketches and CAD features and fitting them to match the scanned data. Once the scanned data has been recreated as CAD data, we can then generate the neutral file based on the final CAD geometry.
The main difference between these two approaches is that a CAD-based neutral file is able to preserve the true geometric features of the scanned part. This means that a cylinder would remain a true cylinder. The same would apply for planar faces, cones, and spheres. This would allow you to create and leverage construction geometry, such as planes, axes, and faces. Being a true CAD shape, any sharp edges on the original part would also be preserved.
In summary, if you are looking to preserve geometric features, use the file for 2-axis machining on prismatic parts, converting the Scan data into a CAD-based neutral file would be the best option.

STL to STEP
Mako-Technics can provide two types of models for you depending on your requirement. You can choose which of the following models you require:
Solid Surface Model
Lowest deviation and a high fidelity model of your part:
With Solid Modeling we will get the smallest deviation from your original part. This is a high accuracy reverse engineering process, easy to be shared with all your manufacturing areas due the small file size and neutral CAD for almost any 3D software (STEP, IGES).
With solid surface modeling you will manufacture exactly the same part you need.
Modify your reverse engineered part in SolidWorks:
Parametric modeling is extremely useful for products that are driven by dimensions. With the parametric approach, engineers can quickly and easily create different configurations of their designs.
The parametric modeling can include dimensions, pattern instances, wall thicknesses, hole diameters and depths, and so on.

Following are the questions frequently asked by the users
Reverse engineering is the technical term for the reconstruction of point clouds in surfaces in CAD programs.
That always depends on the individual case. The effort depends on the complexity of the component in question. In principle, reverse engineering is significantly less costly than completely redesigning an object.
Any CAD program can be used for reverse engineering. If STEP surfaces are required, our team usually works with Design X.
New areas are created to match the existing point cloud. So the entire part is redesigned.
There are many reasons why reverse engineering is helpful for industries. Roughly speaking, it can be said that remodeling enables a better understanding of a product and how it works. Production can also be assessed and optimized using reverse engineering. It is therefore often used for process definition and optimization.
A 3D scanner casts a grid of laser lines or white light onto an object. It can use it to carry out thousands of distance measurements per second. The 3D scanner creates a reference frame using 3D target marks. In this way, it determines where exactly it is in the room compared to the object. It combines all measurements with one another. In this way it creates a seamless surface on the scanned object.
Reverse Engineering as An Important Aid in Industry
Reverse engineering is the technical term for the reproduction of 3-dimensional point clouds that describe a component or any geometry. These point clouds are created from 3D scans or from computer simulations in different areas, but very often in tool planning and FEM calculations.
With the help of reverse engineering, we are able to make this data usable for further use in CAD systems. This results in a variety of possibilities. I would like to use a small example to show how reverse engineering is used in toolmaking to save costs and time.
Example: Reverse Engineering in Toolmaking
1. The master model is scanned and rebuilt as a parametric data record with reverse engineering. The designer can continue working with this data immediately.
2. Material flow in tool design is simulated with software. We prepare the result using reverse engineering so that it can be compared directly with the original CAD data set. Minimal deviations are immediately visible and the construction can already be optimized here.
3. Initial samples are measured using a 3D scan. The resulting data can also be used by reverse engineering to further perfect the tool.
