Re: Help with best 3D printer software
First off, all those you mentioned are not 3D PRINTER software packages. They are for 3D design and used in constructing what is known as a "mesh". They may or may not be suitable in outputting your design in a format that is readable by whatever 3D printer you are thinking of using.
That said, of the those on your list, IMO, Sketchup is the most user friendly and easiest to learn. I have read some of your previous posts and know you are interested in printing an action figure. A figure of an sort will have multiple interlocking parts, and in so far as design, lots of curves. Sketchup is not the best for curved surface modeling as it was originally designed for architecture, but there are many plugins that can help. All the rest, Blender, Modo, Solidworks, etc... have better curve modeling abilities, but they also have a steeper learning curve (pun intended.
). If you are not familiar with 3D modeling, I would find the software you like the best, and can afford, and learn it inside and out before you try to 3D print anything. The ideas in your head will look much better if you do. No quick way around this, short of someone else doing it for you.
