Hi,
 
I have deleted the centre constraining point in sketch mode and am unable to get it back. does anybody know where the setting is to get it back?
 
 

Hoi,Just open your sketch, Click : project geometry and Click on Origine - centerpoint. Its that easy.

I wonder if darren figured it out by now?

Hoi John, I am sure he will,but is not a good thing, not giving an answer, even when it is so simple.It is better to give an answer, so the person nows he's getting help on this forum. I know that some people rather ask somthing instead of try to solve the problem themselves, but where can you drawn the line. I think its much better that every question gets an answer.If there is sombody on this forum who can give one, she/he would do that.I think thats the hole point of a forum, to help each other when you can. When a question stays open, you can delete it after a certain period of time.
