Thank you.
The ArchiCAD 18 version is done, it will be released it this week.
Regarding curved walls etc,
We have been working very hard on fixing existing issues with the existing ArchiCAD infrastructure, we have a solution, it will be released very soon, that supports curved walls! It is not the Norgips solution, it is from a manufacturer of facade cladding, but we will be able to implement curved walls into the existing, Norgips, Knauf and other solutions very easily.
