Most of the CAD and BIM object on Polantis are free : the manufacturers ask us to model their products for BIM and 3D.
But, for some unbranded, generic or specific objects, this is how it works:
the day of your subscription, you get 3 premium objects for free
then, each day of connection, you get 1 premium object for free
To download more Premium objects, you can consider buying packs (5 to 65 objects).
