Why the score become minus?? what happen with the score

I am not sure about your situation but I do know that there have been some bugs in the score and a few people here have taken advantage of these bugs to increase their score in ways that were not indented "cheating". I know there has been much discussion here, on the Facebook page, and in private messages and with the I wish button to GrabCAD about fixing this... But GrabCAD is not about the score so just make nice models and contribute to the community.

I hope you get an answer
