I have a shapefile of a 3d model with various attribute as a multipatch features. I need to export it to collada file, but when i am exporting it, the single attribute is generating a different collada file, but i want a single collada file.
How are you exporting it?
look at this documentation:Multipatch To Collada—Conversion toolbox | ArcGIS Desktop
Also, you mentioned you had the multipatch as shapefiles?
Try multipatches inside of a geodatabase, as that may be the more supported file format.
