Hi. I am using the iPhone to create point clouds for small rehabilitation works. I am testing the apps 3dscanner, Canvas and Modelar. With all of them I have the same problem: When exporting to .e57 or .xyz, the Y and Z axes not only do not have the position exchanged, but also, they are placed in mirror. I have used Cloud Compare with the .xyz import and swapped the z and y axis. That's easy, but changing the sign to avoid mirroring, I don't know how to do it. Any idea? BTW... wouldn't it be easier if this could be done with the library object inside Archicad? (Another suggestion for the "wish list")
Hi, Most of my professional activity as an architect is focused to the reform and renovation of houses in the countryside and also for interior design works. For this type of projects, the use of an iPhone (13 Pro Max) solves perfectly the data acquisition. Its accuracy is more than enough for me (distortion no more than 2%). The recommended distance to obtain the scan is no more than 4 or 5 meters. You have to try which software best suits your needs. I have tried several and, finally, the two I use are "3d Scanner App" and "Modelar". Anyway, if the building you have to intervene on is large or complex, my advice is to hire a specialist with a Faro or Leika equipment, combined with a survey from a total station.
Just FYI, the new version of Modelar (1.7.1) keeps the data in a right-handed coordinate system when exporting clouds and meshes with Z up, which will hopefully help with your mirroring issue. Please feel free to reach out to email@example.com if you're still having trouble!
