A lot of this can already be done in AC3D.

1. A tool whta can unite two objects creating only one, exemple, two squares united one to the onther, and when i select that 2 objects and i united they so its convert in one object and not 2

Use Object->merge to put all surfaces into the same object. You may mean a boolean union though - see http://ac3d.org/ac3d/newin4/#_Toc52769393

2. A torus please! i need make the pistols silencers

Simply make an Ellipse and use Object->revolve to make it into a torus - see the manual for more info.

3. Apply textures to the base of the cylinders

No problem - select the base of a cylinder and use Tools->TCE to reposition the texture.

4. Animation, is teh best solution to a comercial producto fo ac3d and more if you can exprot it to anothers video formats how avi jpeg and wma.
( There is a program called anim8tor and works perfectly with your program, is a good combination)

Yes - future development.

5. Scripts added, or a small program of c++ script to do games or interactives animations

Look into Tcl/TK - this is what AC3D uses for it's user interface and scripting engine. You can modify the tcl files in the AC3D 'tcl' folder.

6. I dunno, but osmetimes the gridsnap works bad (isnt ajust it to the grid)

Please supply more info about this.

7. Is necessary that another window? that of Dos when you open Ac3d

It's not a dos window, it's an 'information console' This is useful for sorting out problems but there will be an option to hide this in future versions.

8. Dynamic ligths (colours ligths and intens¡ity)

Coming soon.

9. Apply trabnsparency to objects and ilumination or more things

Right-click on a colored palette button to edit the transparency of a material.

10. The perspective need better moves, how a "fly" mode or an " free" mode

You can do this - press '2' in the 3D window (or use the 3D menu) to switch into Walk mode. Use the cursor keys to walk or the mouse to 'fly'.

The manual is available on the download page.

Have fun!
