Mariamo - Archicad would probably suit you well.
There is a possible alternative for you though in another Nemetschek program: Vectorworks Designer from Nemetschek North America (there is a Spanish language version and NNA provide Spanish language support).

Where Archicad is a vertical program focused on architecture, Vectorworks is a horizontal program with capabilities in a number of different areas. There is a basic version named Fundamentals which contains all of the core 2D and 3D functionality, but it also comes in four industry specific versions with additional capability:
- Architect: Architecture + Interior Design,
- Landmark: Landscaping and Land Planning,
- Spotlight: Theatre Design and Entertainment,
- Mechanical: Machine Design and General Modeling.
The Designer version contains all four industry specific versions.
Evaluate both and make your decision based on which best suits your purpose.
