Hi
This could be a good starting point

Its available directly in Creator under examples. -

You can do it, I have, but Qt lacks all of the necessary tools. For example every CAD system I have used has a requirement to find the closest point on another graphical--vector projection--which I did not find in Qt. Do not get me wrong, Qt supplies most of the tools for creating and displaying graphics, but not for interactively creating graphics; you will need to add many. I am currently writing a book that fills in most of the omissions.
