We need a web solution for creating, processing, showing and exporting floor plans and add them to complete buildings in 3D.
It also has to calculate floor area by fixed parameters.
For creating floor plans on the spot we need additional iOS and android app.
It must be possible to transfer finished floor plans from app to web for processing there.
Standard is dxf.
We need a full documentation of software and user manual.
Multi language usability is expected.
