The free Sketchup is sufficient for NPR (No Photo realistic) animations ;)

WOW, Thank you Ed and Michael,

you gave me quite good information, I looked on the web but I would never have found these software.

I will look at them,

Thanks again

Thanks Pilou,
I tried to play with sketch up but I did not achieve a satisfactory result.

"You have Adobe flash". Do you already know how to use it? It will do a good job of that type of animation. MoI's next release will have a great hidden line removal export to 2d formats that will load fine in flash...... Use what you already have.

Thanks Burman,

I have already made pretty good 2d animations with flash.
You are right Flash is a vary good software, but I need to work with 3D stuff and flash does not work in 3d. I need to represent a perspective view and it is unthinkable working on 2d for my next project. The first part of the video can be easily made with Flash but if you watch the final one you can realize that with flash you do not achieve easily (or you do not achieve them at all, at least without the support of other software) such alignments and shadows unless you spend a crazy amount of time in there (and it is a parallel view, easier). I was told to integrate Flash with "Stage 3D" but not easy solution.

Thanks for the info about Moi next release. I look forward for that.

then seems cool thing can be done with Sketchup ;)

Thanks Pilou,
I think it is quite good the video even if the animation is not as smooth as I would like to see but I will look at sketch up again.
