I am creating Sketchup Objects using its C SDK. For this I read coordinates of each face object from a text file and accordingly a closed face is created. Most of my objects are L, F, H shaped. Problem is that most of the times, the face edges are a little tilted. Also, many times the corners are curved and not of the Perfect right angle. Is there a way to trim the Edges or process them that we get perfect angled corners? I ll have to finally implement it using SDK, but initially I want to ask if a Plugin is available, or possible for this objective?

I have attached the sample faces that I'm facing. Please let me know.
