Solution
The license system in Diamonds is modular: you only purchase the modules you need.
It is possible to model everything in Diamonds, regardsless of the licenses you have. But at the moment you try to calculate the model , Diamonds checks if you have the relevant licenses. If not, Diamonds gives the message above.
Contact BuildSoft-support (support@buildsoft.eu) to get an offer for the relevant modules you need.
