Gabriel, thanks for your reply, hope you can have this plugin sooner than later. I'm not a programmer, but let me know if I can be of any help. You are correct when you say that waht I want is:
1. Select a face (or group)
2. Input the altitude and azimuth of a celestial object
3. Have the face rotate to face that object
It would be great if the Azimuth would start from the Sketchup North (orange line) and not only at the green axis. If vectors would be a trouble, a line could be used instead, remember that what it is important is the direction at whitch it is pointing, no matter if it's a line or vector. Regards and thank you in advanced for any time you are willing to spend on it. Again, let me know if I can be of any help. Regards.
I might be able to do it, but it may be a few weeks before I really have time to work on it. I'm not an expert at programming plugins for Sketchup, so it depends on how complicated it turns out to be. If it's fairly simple, I might be able to finish it sooner.
Let me make certain I understand what you want first though.
I attached one of your pictures to this post which I think best represents what you are asking. Basically, you just want to be able to:
1. Select a face (or group)
2. Input the altitude and azimuth of a celestial object
3. Have the face rotate to face that object
Is that correct?
It sounds fairly straight forward. I haven't done much with vectors in Sketchup though, so I would have to spend some time learning how to manipulate them with Ruby code.
This project sounds very interesting. Some of the things you requested at the link you gave are actually things I've considered doing myself. Writing a plugin that does all of that would most definitely require many hours of work, but, one day when I have time, I would like to do it.
Thanks for your input!
Gabriel
