I have had a very odd thing happen on in a set of drawing sheets. I modified a section view section line, and... voila, I got most all of my annotations to mirror off of the drawing sheet as shown in the .pdf and .jpg.
I saved a copy of the file and opened it again and all is well. However, I can generate the same error at will by modifying the section view line. I thought a sheet regeneration would rectify the sheets after seeing that they were okay after a save, but that does not work. As there is a work around (to save, close, and re-open the file), this is not a make or break deal.
Any ideas on what's up? Has anyone ever seen this before? Why wouldn't "all" the annotations mirror, I wonder?
