Creating CAD from objects through reverse engineering.
Scanning and measuring products. From there, we create 3D CAD data and drawings. Please use our services for re-molding products with lost data or for digitizing improved machined products. We also accept modeling from drawings and STL files.
When there are no drawings available for remaking an aging mold, we will create drawings that are faithful to the sample.
At So Engineering Co., Ltd., we measure products without design drawings and create faithful drawings based on samples. Please send us the actual product, or let us know the product photos and approximate external dimensions via email. We will provide you with a quote promptly. We are seeing an increase in cases where there are no drawings when reconstructing aging molds. Please feel free to contact us. 【Request Process】 ■ Please inform us of the approximate external dimensions via email → Quote ■ Measure and extract the dimensions and shape data necessary for drafting ■ Construct and create drawings in 2D or 3D CAD data according to your requirements ■ Submit the data in the specified format ■ After that, we will issue an invoice and return the product to you *For more details, please refer to the PDF materials or feel free to contact us.

Even without the drawings, as long as we have the item, we can take photos, create the drawings, and manufacture an equivalent product.
Started Reverse Engineering Services With the introduction of 3D scanning, we are now able to offer reverse engineering services. Reverse engineering involves analyzing the structure of a product and creating specifications such as manufacturing methods and design drawings from that analysis to produce the product. In simple terms, even if there are no drawings, as long as there is a physical item, we can take photographs and create drawings to manufacture an equivalent product. If you are facing difficulties with products that only have the physical item and no drawings, please feel free to contact us.

I will introduce two methods of reverse engineering based on 3D scan data.
There are various methods for reverse engineering, and the choice of method affects the output data. Therefore, it is necessary to select the optimal method according to the purpose of data use and required accuracy. We will introduce two methods of reverse engineering based on 3D scan data, along with their procedures and characteristics. <Reverse Engineering Based on Cross-Sectional Contour Shape> [Step 1] Acquisition of shape data (point cloud data) using a laser scanner. [Step 2] Polygonization and mesh correction. [Step 3] Modeling is performed using 3D modeling software and 3D CAD software. A sketch of the cross-section is created on a reference plane, and solid shapes are generated using functions such as extrusion and rotation. <Reverse Engineering Based on Surface Shape> [Step 1] Acquisition of shape data (point cloud data) using a laser scanner. [Step 2] Polygonization and mesh correction. [Step 3] Modeling is performed using 3D modeling software and 3D CAD software. A surface that fits the mesh to the surface shape is created for all surfaces to generate a solid shape.

We will introduce a method for reverse engineering simple-shaped workpieces with higher precision.
Commonly used methods for obtaining point cloud data for reverse engineering include 3D laser scanners and X-ray CT devices. However, regardless of how precise the equipment used is, an error of approximately ±0.05 to 0.1 mm occurs during data acquisition. Since the scan data is based on these initial errors, it can be said that achieving highly reproducible reverse engineering is nearly impossible. To improve reproducibility, there are methods to correct CAD drawings by incorporating actual measurements using calipers or micrometers, but there are limitations to the shapes and dimensional accuracy that can be measured with small tools. Our company has been providing measurement services using high-precision measuring instruments such as three-dimensional measuring machines and shape measuring machines for many years, enabling us to perform high-precision reverse engineering leveraging our advanced measurement technology. In this blog, we will introduce high-precision reverse engineering methods for simple-shaped workpieces.
