Hi, as far as I can see, a lot of community members have a problem with windows.
I would like to share the macro I did during the RC4 Beta test.
The macro creates a window frame that can be open, tilt, slide, etc. Basically All-In-One

The video on the link shows how everything works.
https://www.youtube.com/watch?v=QTGXqxQVI-EAs the macro emerged during beta testing, the number of parameters increased as the Beta progressed so it is quite complex and maybe not suitable on the large scale projects. Also, there is a possibility that there may be a bag or two so please report it and I`ll try to fix it.
Anyway, I hope someone finds it useful.
Scene contains 3 RC object:
1. Based on the X/Y size.
2. Based on the Linear Spline and Parameter for Y Size (could be used with Marker workflow to use user data for e.g. Y Size)
3. Based on the Clipping Spline (First Vertex should be at the bottom left corner of the spline segment)
Best Regards.
