Thank you for the hint. I haven’t worked with meshs so far, only stl and gcode, and I think I have to get familiar with mesh manipulation if I want to get most of the Pop 3D-scanner.
The “holes” I meant are not real holes in the scanned object - like for srews as you mentioned - but areas which are “there” in the real model, but which the scanner doesn’t recognize. Trying to make a “selfie” face scan, for example, I mostly have such “holes” at both sides of the nose, where the nose slopes into the cheek. And I can’t get the scanner/software to recognize that there is surface, too, no matter how I move the scanner or angle it. (And my face doesn’t have those holes )
It might add to the problem, though, that I’m not used to the right way to move the scanner yet, without getting the “lost track” message. Reallignment often works, but more often produces artifacts when the parts already recognized are alligned with wrong parts of the scanned object.
It’s a learning process, and I’m still confident to get good results in the end.
