Hi there,

Currently running Revit 2017 & Windows 10.

Quick question, when rotating a 3D house (hypothetically), you select all 3D elements, and then in a plan view, rotate to the degree required. Sounds easy enough.

My question is, why do some elements not rotate despite being selected as part of the rotating process? Refer to my screenshots for before and after rotating. I have only rotated 45º but you will see in the "After" screenshot, the elements which did not rotate.

Is there a simple fix to this in the family properties, like a tick box or something that I'm not aware of?

Some of these families are wall based, so I can understand that they rotate, and that is proven in my exercise.

However for example: "Plumbing Fixtures"

The 2 bath families

 - One freestanding

 - One Built-in

Both of these families are not wall based, yet rotate with the rest of the elements

The 2 basin families

 - One single vanity

 - One double vanity

Both of these families are not wall based and do not rotate with the rest of the elements.

Most of these families have been created from scratch, and some have been downloaded from the RevitCity download content, and modified as required.

Any help or advice would be appreicated.

Thanks in advance.

i dont know why you are rotating the whole project , and i have no theories why these families doesnt rotate when selected with other elements , but if they can be rotated alone use a multiple rotations with a defined center of rotation ,

and anyway wouldn't be easier to rotate the project north or the project true north ? just brainstorming ....

In this instance it is not the Project North we want to rotate. I have found that when I select all the elements which do not rotate, and rotate them separately it works.

Just can't work out why as a whole, all these 3D elements do not all rotate with each other.

i gave it a try and tried to rotate a part of my project consistent with multiple categories ( Str Columns , Furniture , Pluming Fix , Groups , walls , Grids ) and everything went well , so my suggestion were you sure that you are selecting the whole items sometimes you miss selecting pluming fixtures because of view range ?

Edit: sorry didnt check your screen shots well selection was right

Yeah I'm not 100% sure why it's doing that either, but thnanks for trialling it out.

Might be something I need to modify in the families.

EDIT: Not sure why I was having this problem, but I created new families & copied in the 3D modelling for each family not rotating, re-loaded into project and now it rotates with the rest of the 3D.

Update on my previous edited post:

The families which have dimension parameters to adjust sizing etc, are the ones which are not rotating with the rest of the 3D.

Are there any properties when setting up dimension parameters which affect families when loaded into a project?

Why are you rotating like this, why not use the built in tools?

Sorry WWHub, what do you mean by built-in tools? Do you mean the other Revit tools like "Rotating Project North" etc ?

First question is, what are you really trying to do - not your process?

Did you know that you can rotate a view?

1. First method is rotate a view on a sheet.  Everything turns on the sheet including text and title.
2. Second method is simply rotating the view.  Turn on the crop region, select it, then rotate it.  This turns the view but all annotations remain as normal to the view.  They do not rotate with the view (except dimensions).

Look at the attached image to show the choices.

If the building needs to rotate in relationship to the site but project north remains the same, simply rotate the site!

And finally, there are the rotate north, rotate project north and yse - choose the elements and rotate them.  << I really don't think you want this last choice.

Thanks for your response.

To clarify what I am trying to do, is simply rotate the 3D elements in the project. We use this procedure when we are better orientating a building in regards to its site, ie sun/breeze path etc.

Sometimes the building may only need to be rotated 10 degrees but makes a better design in the process. In some cases we have a collection of buildings which may sit side-by-side on the site, but each building has been rotated slightly to better that particular building's orientation.

I am aware of the procedures for rotating a view on a sheet, rotating the crop region, and rotating the site, however neither of these solve my problem. As rotating the crop view applies to that view only, rotating a view on a sheet is for soley that sheet, and rotating the site would mean the bearings entered from the Title Survey plan would be altered.

All I am really asking for is if anyone else has encountered this problem & how they resolved it. Perhaps I will just need to do some more trial&error work myself in the families I know are not working to resolve it.

Thanks everyone for all your advice and help so far.

Try rotating the elements that do not seem to rotate individually. For instance the furniture. I rotated full projects before because the existing buildings and the terrain were to be unchanged. I never experience this problem before. I placed the elements I wanted to rotate in a separate workspace, and all went fine with the rotation.

I have seen/read in a autodesk post that one can temporarilly place all elements in a group and move/rotate. Never tried but seems logical. See if that helps.

Set your view to true north and rotate true north as required.  All of the views set to Project north will remain normal to the screen.

Thanks for your feedback archigrafix. I tried what you mentioned about placing into a separate workspace & rotating and that didn't work. However, when I grouped all the 3D elements together into a model group, then rotated, everything rotated fine.

I'll just have to remember to un-group the elements when finished, and delete the model group from the project browser.

Thanks again.
