How to adjust the start point of a circle alignment??

[scott.clark]

I am creating a circle alignment want to have the start/zero point at a specific spot. it always wants to start to the right of the circle. I have adjusted useing the civi3D propertys but it puts a negative number at the original start point and messes up the chanage. 

Attached is a screen shot with what I am looking to do. Second image is what happens when I change the reference point to where I want the start chainage to be.

Any help would be appriciated, I'm on a deadline...LOL  

Thanks

Could you just rotate the alignment about its centerpoint after it is labeled?

Well go figure, that worked.... guess I was thinking way more complicated then it needed to be.

Thanks Mike.

I hope you are not planning on doing much with this alignment, particulary something left and right of center line.  This circular alignment will always be looking at itself when going either left or right.  Confusing.

Thanks Bill, I'm not sure what you mean. I will be using this alignment as the main corridor for my roundabout

I have also just noticed that although rotating the alignment to the correct start point worked for me, I just noticed that if I save the drawing, then reopen it, the zero start point defaults back to the original posistion before I rotated it.

Why would this be?

I just think Civil 3D doesn't like closed alignments. Can you make the alignment an arc with a very small gap to approximate the circle?

yes it revert to original situation. how can it be solved?
