So take TwinMotion! ;) (free personal or not if commercial project)

Not yet tested but seems amazing! There is a free version "online"!
You can import your own volumes 3D!
No animation at first view...

in less 3 hours! :)

Sorry guy above shows hundred of cars but not how use the tools!

This is a better one!

So you can even make animation inside Vizcom! :)

A new one! Online! A free version is existing!
accepts 3dm format!

... but queue rendering is some long so better to make a SnapShot of the Sceen's work! :)

I can only recommend Blender.
You can follow tutorials to do what you want and move on, but I recommend learning it.
Its learning curve is not that steep. learning 3D in general is somewhat hard.
If you know 3D, then Blender won't take that much time to learn. If you don't know 3D, then Blender is the best place to start. Otherwise you'll be facing many problems and limitations with any software you use, and I'd argue it'll take you more time to know what you're doing and to learn the basics.
Also, Blender will be the future of 3D. I'd argue that its position is already cemented, but in the future, many horizons will open if you know Blender deeply.
