"does anybody can indicate any modeling program that can help me?" My answer depends of what you want to do, aircraft or building modelling (for scenery)? How complex will be your objects and if you've experience with modelling/texturing before. Well, most of people here will suggest you free software, me too, but if you don't want to use blender, its ok, there're some alternatives;
K-3D, something like Blender but lighter or easier, its a free open source tool
Wings3D, another open source powerfull 3D tool
Sketchup, commercial but free of charge using older versions (before 2015 editions), perfect for beginners and easy modelling.
There're other commercial software; AC3D, Maya, etc, all usefull if you've 3d skills.
What you need are just .ac generated objects, all these software can do the work, depends of your needs and skills to select the best for you.
