Summary: It's too easy to accidentally delete or erase a Civil 3d object. There should be a warning and/or confirmation required before deleting something important (like an alignment)
Description: I've been working on a large project for months. Today I noticed that one of the miscellaneous alignments is missing, and not only the alignment, but also the corresponding profile and the corridor targets that referenced the alignment, which in turn caused changes in the cross sections. From looking at backup files, it looks like the alignment was accidentally erased a couple of days ago. When an alignment is deleted, Civil 3d automatically deletes any associated objects (like profiles, sample lines, etc.) with no warning. There needs to be some kind of a warning. It's too easy to really screw things up.
