[Mi...] Posted September 7, 2022 Share Posted September 7, 2022 I have had this happen before and ended up deleting and re-smart teaching the measurement series. So I have to ask the question..... Why does this happen to 'good' scan data and how can i fix it without the drastic action mentioned above? Link to comment Share on other sites More sharing options...
[Mi...] Posted September 7, 2022 Author Share Posted September 7, 2022 As can be seen the top and bottom of the scan data look clean. The top and bottom of the mesh don't. Link to comment Share on other sites More sharing options...
[Na...] Posted September 7, 2022 Share Posted September 7, 2022 Hello Michael, you scanned top, then bottom, transformed the measurements and the "spaghetti mesh" is the result after the polygonisation? Could you provide us the project with measuring data? Regards, Nanno Link to comment Share on other sites More sharing options...
[An...] Posted September 8, 2022 Share Posted September 8, 2022 Hello Michael, is there any edge curve in your project with the measuring principle (MP) "gray value feature (mesh adaption)"? We had a similar effect on the meshes with some of our projects using this MP... With the MP "gray value feature" without mesh adaption the meshes were all ok.

[Mi...] Posted September 8, 2022 Author Share Posted September 8, 2022 Please sign in to view this quote. Nanno, We scan in a measurement fixture with a single skin CAD. I showed both sides of scan data to show it is clean with no data mis-interprettted as the underside of the panel. I have just read Andreas' post and that could well be the issue. For reverse Engineering our Design Team want clean mesh edges so edge curves with gray value feature (mesh adaption) measurement principle usually works. I will switch to gray value measurement principle and report back..... Link to comment Share on other sites More sharing options...

Solution [Na...] Posted September 8, 2022 Solution Share Posted September 8, 2022 Hello, I found the issue and will link this post to it. Workaround is to find a loop on the curve, which shouldn't be there. When the GVF measurement is not used for the calculation the curve and polygonization should be as expected.
