Webex Meetings for iOS uses SceneKit Scene Document (SCN) files to use augmented reality (AR) sharing. If you have a CAD drawing, you can convert it to the SCN format to take advantage of AR sharing on your mobile device.
Create an SCN file using 3D creation and editing software.
Import the CAD 3DS file into your SCN file.
If there's any unneccessary objects in your 3D file, you can edit or delete them.
Export the file as a Collada digital asset exchange (DAE) file.
Import the DAE file into an integrated development environment or file conversion software that can convert DAE files to SCN files.
Export the file in SCN format.
If you're using software capable of editing SCN files, you can correct wrong coordinates, add missing datas, or add textures.
