Importing 3D Models from 3rd Party Software

I have recently purchased Animate Pro 3 and I am trying to experiment with creating 3D environments in the software. What I am wondering is that would I be able to import a round model, such as a tree, from another program, such as Anim8or or GIMP? If I am not able to, how would I be able to simulate this?
Thank you for your help, I appreciate it.

You can’t import 3d models into Animate Pro. Only Harmony and Storyboard 3D and v4 has that functionality.
