Problems deleting bad alignments

I just noticed I had a google search on my blog for deleting bad alignments. I can offer some tips on how to take care of this and why there is a problem. Civil 3D is a dynamic based platform. Just like in Land Desktop, where you couldn't delete a layer if it was being used -- in Civil 3D, if there are any entities using this object, then you will not be able to delete it. For an alignment, the two things to look at if you are having problems are the profiles and profile views attached to the alignment. Make sure you delete those from the prospector in order to get the alignment freed up.
