3-matic’s CADlink module makes reverse engineering of any freeform geometry a piece of cake. Its advanced splitting algorithm automatically breaks up freeform geometry in optimal patches for export to IGES or STEP format. Combine the splitting algorithm for freeform surfaces with traditional segmentation tools, and you have full control over the reverse engineering process and result.

Following the forward engineering principle, 3-matic allows you to make design changes directly on scan data and perform complex repairs, without having to go to CAD. However, 3-matic’s CADlink module can convert your data to CAD when dictated by further steps in the production process.

The CADlink module offers swift and accurate conversion of freeform geometry to CAD. For complex geometry, where segmentation is a necessity, manually splitting geometry in definable patches can be a time-consuming job. Using 3-matic’s CADlink module, a splitting algorithm for freeform geometry automatically splits the entire geometry in definable patches of similar size. The number of automatically generated patches is limited, making sure you will not end up with an excess of small patches.

The advantages of the CADlink module become even more apparent when combining the manual and automated methods for segmentation. On an initial segmentation, feature recognition is performed first, ensuring that CAD-like entities will be exported as CAD entities, such as planes, cylinders, etc. Recognizing the CAD-like entities this way guarantees that features are kept after conversion and reduces file size. This feature recognition allows you to start working with a specific CAD entity immediately after conversion to CAD.

On the other hand, a larger nurbs surface in the region of interest can also be obtained by making a separate segmentation of this area first.

In addition to IGES export, you can also export directly to STEP format.
