Application for recording ratios to the surface or using a configurable unit for building projects or Plumbing - Heating and ventilation.

The backup is done through a database to be recovered on compatible equipment SQLITE format.

Allows you to search a ratio, to register new ratios and save and load databases ratios.

Lets you quickly encrypt a project by calling it from the database and entering one of the parameters for which the ratio has already been established (surface or other unit).

More details of the application on my site.

Free version comes with a minimalist base ratios given in the building. Everyone is free to form his own bases from the application or database SQLITE that can be imported.
