I do not wish to say what is my project. Lets say I am creating a new kind of bicycle for example, and I am looking for investors and they asked for prototype. I did not create the physical prototype so they asked for some kind of 3d model, like the ones used in industries (I know they use maya or 3d max)
I do not know how to create 3d models and how to apply real world physics to it, for example, how much force does it take to knock the model off the bicycle and how my new bicycle would not let him fall etc, I just invented something and want to show the investor a model of it and how it works in a simple 3d way, highlighting the different parts between my bicycle and those available in the market . just an example.
What is the best software to do a simple presentation of something like the example I showed above, a software that is so simple to use, like makehuman.org for instance, something that would give me many 3d models out of the box, let me manipulate them, so that i can create a decent prototype in a couple of hours + real world physics, at least gravity, or maybe I can write the equations but not a must have.
Ideally, I'd like it to be a freeware. Running on Ubuntu 14.04 64 bit, but I have windows running in virtualbox.
I know you would suggest blender, anything more simple than blender? Created with simple presentations in mind? the animation and the graphic engine don't matter to me, what matters most is to get my prototype done. Even physics engine is not a must.
It doesn't even have to provide 3d models if i can import any 3d model to it, all it has to do is to provide a friendly, easy to use interface, with prototyping in mind, not game development. Because I can find many 3d models on the web.
