Merging two scans of one part into a single mesh

[[An...]]

Hello,

I am using ZEISS INSPECT 2026 (free version) and need help merging two scans of one part into a single mesh. The part was too long to scan in one go, so I scanned it in two sections and have two STL files. The scans overlap in the middle of the part. In the overlap I placed four magnetic letter markers (just physical markings), one on each side, and they are visible in both STL files.

Goal: one complete, accurate mesh of the whole part.

Hi Anu,

if you have two separate meshes like STL, it is not possible to combine them with the free version of Inspect. The professional version supports multipart projects. Here you could align the meshes using the markers and other features, then combine them after stitching (ZEISS Quality Tech Guide) or some other mesh processing. You might try the trial version of professional first for this.

Do you scan the parts with Inspect? Then you could combine the measurement series in one project, which will also result in a smoother result, because the measurement series are polygonized together. (ZEISS Quality Tech Guide)
The measurements are also transformed accurately by reference points with this method.

Hello Nanno!,

Thank you very much for your help with my question.

The part was scanned with a Hexagon Romer Absolute Arm 85, and the scan software was PolyWorks. I only use ZEISS INSPECT 2026 for the inspection.

Since the scans do not come from a ZEISS system, I understand that combining measurement series is not an option for me. I will try to merge the two scans in PolyWorks first and then import the single mesh into ZEISS INSPECT. If that does not work, I will test the trial of the Professional version.

Best regards,

Anu
