Linked model cannot unpin

[chubbard]

I have a linked model on B360 that i cannot unpin and move. Never seen this before Revit 2020. Any way around this? 

the design team didn't align the models properly so i need to rotate and move them to use properly. 

3 models 3 different coordinates, incorrect rotation, used Scope box to rotate. So now i have move and rotate them. Strange part is 2 of the models can be unpinned and moved, but the other can't. All are workshared B360 models and were all established the same way.

Just spit-balling here... 

Are you sure the immovable link isn't an attachment in another link?  

...how about workset related?  

[chubbard]

Well the other two models do not link back to the problem model, but they do link to each other. But removing all the links and linking just the arch model (problem) using center to center seemed to fix the issue. 

I did open all three links and removed any links in those models but all were overlay and absolute path so i don't see how they would have seen each other? 

I had heard that there was some feature that ensured all B360 models were properly aligned in 2020 that prevented people from moving linked models linked by shared coordinates. I cannot find any documentation so i used center to center.

This???

No that is for Glue Classic only AFAIK. Its possible these models were loaded into another B360 site as linked models but that is all i can find that might explain the behavior. Not sure how these models were being stored/accessed I received them from a third party and they had already been detached and saved somewhere else.

But you are rocking and rolling now; right? Or do you still have the immovable link issue?

Linked files using shared coordinates are pinned in 2020. You need to disable shared coordinates for the link to move it and then resolve the shared coordinate relationship again.

I thought I heard something about this, but cannot find any documentation, nor any real process to resolve short of removing all the links and starting over. I think it makes sense for a team that has established coordinates but its a disaster for people who receive models from others in various states of coordinate location. 

This set i got 3 models, When linked together origin to origin, 1 structural was a few hundred feet in the air, other structural  a few hundred feet below ground and the architect was rotated 91.42d but at proper elevation. The architect rotated a scope box to get the model to fit on a sheet, but the engineer rotated project north, though in two different directions on each model. Feels like the structural models were done by two different firms. 

I am guessing this is falling into the cracks between the Revit and B360 teams.

Sorry you've got a mess on your hands. It does sound like it needs an overall reset.

Base on what I've read so far, I'd disable Shared Positioning. Then have everyone move their project base point to mark the same model location (like Prime Grid intersection A/1). Then since you can see linked file PBP (and Internal Origin, Survey Point) now you can move the links so they all line up properly.

Then you can deal with the shared coordinate system if you really need it. If you do then decide which model is the boss and Acquire Coordinates from that model while working in the remaining models.

[chubbard]

Yeah well their not going to do that. We tried to alter the shared coordinate in the arch file and it blew all the views up since they used a scope box to rotate., plus the project north rotation. 

We cannot get architects here to stop using the shared coordinates just because. 90% of the projects don't need it except for a site rotation. But they move it unclipped, clipped up down with rotation etc. Models never come back together right and it messes up downstream uses like IFC and NW. This project certainly didn't need it. 

So we blew all the links out and came back in 1 at a time C-C and moved them. What was weird is B360/Revit remembered and i had to download the arch file and delete it off the site and re-collaborate it to get the pin to release.

Can't wait till these get to NW. Going to be a Charlie Foxtrot for sure.

Okay good luck! Mastering software is only a tiny piece of the puzzle unfortunately.
