import text strings into Unity editor 3D text objects so that Scene View displays them

I am having trouble finding a solution to this problem. I want to generate the text for TextMesh.text in a custom application and import into the Unity editor so that I can then scale the text to fit. If anyone could point me in the right direction to simply edit a 3D Text game objects’ text mesh.text property from a script so that it is reflected in the scene view in Unity’s editor, I would greatly appreciate it!

Best Regards,
Ben
