Curved ceiling

[Anonymous]

Hi.

I’m a long time ArchiCad user but I can’t find a good solution for these two dilemmas:

A)
A curved ceiling made up out of thin wooden beams (image).
The problem is not to model this, but how to effectively change the curvature during design phase without having to model it over and over again. I’m aware that a Rhino-Grasshopper connection could solve this parametrically (a controlling spline and all the beams perpendicular to this) but is a similar solution possible within ArchiCad?

B)
I have been looking in-and-out of the web for a north-arrow/3D-sun object that shows the angle of the sun as a line in 3D based on the global sun-settings. Does anybody know of such an object or add-on?

All comments greatly appreciated.

Yes, I noticed that now, I need to play with the settings to see how to fix that.
