Rotating Project North - Some Objects Don't Rotate

[jonalyn_abraham]

We are currently the interiors architect for a pretty huge 2015 project (400mb). The AOR did not rotate the project to project north which would have caused a whole lot of issues when beginning to detail out each space. Long story short, we decided to rotate to project north but now have to rotate it back.

When I rotate the model back, it goes well, until I realize that seemingly random objects do not rotate. This is a problem, because certain pieces of furniture rotate and others don't. Any suggestions?

How were those other families created?  I have seen this issue when DWG's are inserted in a family instead of using native Revit construction.

Definitely not with DWGs. They are pretty simple families, mostly casework, generic models, and specialty equipment.

Same thing here. As you say, rather random object are not rotated; generic models, furniture, plumbing fixtures. If _none_ of those families was rotated, we had a pattern. For example, there's a table (furniture) with chairs (furniture) around it. The table is rotated but not the chairs. I checked those families and I don't see anything odd. So I wonder what the explanation is for this 'feature' and how to resolve it.... (yes, I know, start modelling the right way in the first place).

Shot in the dark - group objects? Maybe one humongous group of the entire project? At the very least try grouping the non-rotators with the rotators?

Yes, tried that too, but no - it won't budge. Also tried linking the file into a new file, rotated the link, then bound it. After the bind-operation, everything is rotated, but a lot of stuff is deleted (like curtain walls). So unfortunately, that's no work-around too.

Luckily, the project in question had just started, so there wasn't a lot of stuff to rotate. We rotated  'Project North' and then manually rotated the left-overs. Everything turned out fine, but it took a lot more time then we expected.

am i missing something here - project north is not something that can be rotated? as best i know..... its just a description of the model orientation as it sits in model space. project north is simply 'up/down' page and is a notional device for describing how a view-port will appear on a page/sheet. TRUE north is then rotated by describing the difference between project north (page orientation) and true north (real world orientation)......

if you want the viewport to orientate differently on the sheet without rotating the entire model (which seems to give you an overhead to fix) then you can simply rotate the viewport on the sheet to get the orientation you want????

A viewport can only be rotated 90 degrees and text rotates with it. Not good for standard drafting practices.

He meant rotating the view's crop region, which is able to be rotated at any angle. It's different than rotating a viewport on Sheet.

haha

yes i have missed something - however - having tried it (now) i cant help but notice that its not project north that rotates - its most of the elements within the model that rotate within the project north..... most - being the operative word here......

are the effected elements , components or families pinned?

are any of the families modeled in place families?

Yes, Rotate Project North is quite ambiguous. It should be Rotate Project just as Mirror Project. Anyway, now you've seen what happens; any clue for a cause?

No and No.

unfortunately not.... i had a similar thing with 'rotate project' and discovered the workaround to rotate the crop region. it was the easiest and quickest way for me to get the results i needed - otherwise i would have had to go to each piece that hadnt rotated (having 1st checked and found them all!!) and do a manual rotate... on a 350mB model this wasnt practicable

and so i worked out the rotate crop region workaround....

this answer is from 2014. The Revit 2017 should be able to rotate everything, I guess.

Unfortunately: No. Just tested Revit 2018 and still the same.

I just had this happen in Revit 2020.

Seemingly random objects are left behind ( a few hundred of them). Some are in design options, some are in the main model. Different types of families, regular and inplace. 

As far as I can tell they don't have anything in common.

I also found that it deleted a couple of elements. I know for sure because I made a backup just before and just after rotating project north and a few inplace models are completely missing from the rotated model.

[ToanDN]

This is not new. I would avoid rotating project north at all cost and to be honest, I have never found a good reason to do it.
