This is a 3d extension for thunkable and appinventor.
The extension still has a lot of imperfections, at the moment does not support the import of external models, I was making a parser. However, I am a high school student and are going to start school soon, so I may not be able to update the parser for a long time. Currently supporting the creation of simple geometry such as boxes and balls, you can create a new model by creating a composition. aia already contains the basic usage of this extension. If you want to do more about coordinate transformations, combine VectorMath (My LinearAlgebra Extensions)
It still has many problems, so for the time being it is not open
