Your project - your credits

Select your credit package depending on the complexity of your project

"XS" - the small credit package:
60 credits

60 credits is enough for a very simple roof. Ideal for testing. In any case it is a good start. Why not give it a try?

"S" - the basic credit package:
150 credits

More than an outline with four corners or a simple single-family house, but still clearly arranged? Then you are well served with the package "S".

"M" - the workhorse among the credit packages: 
300 credits

For 300 credits you get the calculations for an all-round perfect roof with all corners, edges, drainage and collision objects.

"L" - the credit package for frequent users: 
600 credits

Are you designing a shopping centre or a concert hall? Many projects are to be calculated in the near future? Create your credit stock now!
