Each of the building elements has groups of parameters that describe it. These can be geometric parameters (dimensions, volume …), physical (thermal conductivity, density …), position in space, connections with other elements, appearance, etc. Thus, the 3D model is essentially a database of building elements and their interconnection. Programs for 3D design visualize the content of this database.

It may sound complicated, but this approach allows to obtain results unattainable by traditional methods:

• To show the complete interconnection of volumetric graphic images on the model, their parameters, related specifications;
• To control elements by programming their parameters (the so-called parametric modeling);
• To determinate automatically the intersection of structures at the design stage.

Obvious benefits from using a 3D design approach:

• Increasing in the speed of development of project documentation;
• Improving the accuracy of design decisions;
• Eliminating up to 90% of errors in the design of constructions and engineering networks;
• velocity in making changes to the project;
• The possibility of associating a construction model with other software systems (for example, a budget program or project management tools).

A well-coordinated architect is ready to work for the company to create 3D models. My knowledge and little experience in modern software can do each project efficiently and with optimal design solutions.
