My viewports are doing something weird.
I know for a fact that my viewports were in the correct location, at the correct scale and they were locked. To give you a little background, in my plan sheet drawing I am showing a plan view and profile view and I use 2 xrefs to do this, my master plan drawing and my profile master. I was switching between the profile master and my plan sheet drawing doing some adjusting to the profile master's profile VC labels and making sure they will fit into the viewports I made in the plans sheets. As I am doing this editing, I am saving the profile master and reloading the plan sheet drawing. After I come out of the reload in my plan sheet drawing, every single viewport that shows the master plan xref was reset to a position way out in left field. This makes absolutely no sense because I wasn't working with the plan view viewports and I am 100% certain they were LOCKED. How is it even possible that they get moved if they are locked?
I am able to get around this problem by re-aligning my viewports to their correct position, its just annoying having to do this again. I would really like to know what is causing this so I can prevent it from happening again.
I use 2013. I have 2 viewports per layout, one for plan and one for profile but they are both at the same scale. It was the plan viewports that messed up even though I wasn't doing any work with them.
They were created manually. I used the copy layout feature create the next sheet along my alignment and adjusteed them by hand. This problem is not drawing specific, it has happened in two different drawings. Glad you mentioned the plan production tools though. Looks like I have been creating sheets the hard way.
Thank you for the additional details. The fact that you are copying layouts may be the key to the issue. If you have a "bad" viewport you may have copied it to each layout tab and magnified the issue. You may want to try to create new viewports and see if that helps, or try out the plan production tools and see if you get a better result.
I think I may have figured out what is causing my plan viewports to mess up and reset. On each of my plan viewports I have a north arrow block attached to it that auto rotates to the north direction of what is being displayed in the viewport. This feature is under layout tools -> North Arrow. Now I have 2 drawings where I have had my plan viewports bug and in every instance I had a north arrow attached to the VP. I should note that in the same drawings that my plan viewports bugged, my profile viewports did not (I assume because I have nothing attached to them). I am using a custom north arrow block that keeps the "N" vertical and rotates the arrow as needed. The bug may be simply the custom block I am using not playing nice with the North Arrow feature under Layout Tools, or the program may not like the quantity of north arrows attached to viewports in each drawing ( I have 11 in one and 10 in the other).
I can simply not use north arrow feature under the layout tools to get by, but should I be reporting this potential bug somewhere? If so where?
This is something I can report for you if you like; however I am going to need specific steps to reproduce. I tested this on my own, and my viewports seem remain intact no matter how many north arrows are used in the drawing and layouts. Could you try this minus your custom north arrow and see if it performs the same?
If it is not reproducible with your custom north arrow then I would have to assume that something is wrong with that block or whatever you used to create it. Maybe try recreating it and see if it still happens.
