However, you could make sure the model is saved, then close it (ie, by starting a new empty model.)
Open the model file with the C API and add your guide points.
Then save it with C API, release it and then reopen with the Ruby API.
Sorry for this mistake, about 9 months ago my PC was hacked, my personal accounts were cloned, so possibly those who were trying to harm me made these posts.
Until now, I was not aware of this post.
I have already deleted it, please check if the file is still on the forum.
Thank you in advance for notifying me of what happened, this way I was able to delete it so that it wouldn’t cause any more trouble on the forum.
