It also goes without saying that you should have a backup in case things go awry.
Hi, I forgot to mention that when you mirror the alignment point area, DO NOT mirror the alignment point and the alignment rectangle. Just mirror all of the contents inside along the same axis in reference to the alignment point you are mirroring.
Hi, I have a solution to this. If i want to mirror a design master plumbing plan, I would remove the design master database from the folder first and place it in a location where i can easily retrieve it later. Once I do that, I HAVE to mirror each alignment point area separately. You will also have to mirror each alignment point area along the same vertical/horizontal axis in reference to the alignment point area you are mirroring. When you remove the design master database, designmaster won't automatically auto-move any risers. Once you have finished mirroring everything, drop the dmdatabase back in and coordinate and update drawing graphics. I've only just done this recently to a project prior to writing this comment and everything looks good. If i get any issues, I will come back and post. Cheers.
