Export plan from view map to DWG, keep rotation

[DangCad1]

I work in a project where I've rotated the plan in Plan View 23 degrees. When I export the file to DWG, it exports with no rotation.

Is there any ways to change this, so the exported DWG follows the rotation chosen in the view map? I would really like to prefer to not rotate the model itself.

Bumping this.

The IFC file uses True North typically. Make sure you have some Site Information added to the Site fileds in Project Info. I think you might need this for the SUrvey Point to actuall behave.

Check your translator to see that exporting with the Survey Point is de-selected.

In IFC exchanges, the survey point orients the output to True North, and I belive the behaviour is the same with background DWGs.

Thanks, but unfortunately that's not it. The translator has "Project Origin" instead of Survey Point chosen in "Match File's Origin", and I can't find any other setting in translator where Survey Point is an option.

I start to suspect that it's simply not possible to export DWG:s with the same rotation as in view map, but I can't be the only one missing this feature?

I am wondering if that is because you are simply saving the plan view as a DWG?

If you place the view on a layout (with the correct rotation) and then publish that layout, I think you may get what you see.

Just a guess.

I am not really sure as I have no need to save/publish rotated DWGs.

saving rotated views is critical for campus and compound style projects, where buildings are not orthogonal to each other. 
I am running into this same issue with one of my clients. They need to marquee and save each building orthogonally; but none of the buildings are ortho.
I am going to try to run them through a translator set up that will save to paper space with x-ref; but thats borderline usesless as well. It's true, the resulting paper space will LOOK correct, but no structural or MEP guy is going to want to work in an x-ref; and whatever they send us is going to have random origin (0,0) relationship.

@DangCad1 ; I do have a method used for years now for dwg > model space export. If you copy/paste your plan into a worksheet, you can position/rotate the resultant linework and fills as needed.
this gives the added bonus of being able to run linework and fill consolidation, and even find/select lines on each layer/pen and unify into polylines.

...

just be careful, as this is a slippery slope. You may find yourself getting cleaner and cleaner results, spending more and more time prepping dwg output... and consultants wont want to go back to the dirty 3,000,000 fills and 10,000,000 lines/pllylines that they are used to receiving... and you may spend days getting files clean enough for them (speaking from past experiences).
...
my recommendation is to always save as-is from the view map (marquee if needed) and solicit a response: "is this going to work for you". If they say yeah, then they can deal with plan rotation on their end. Don't spend a week doing something they can do in an hour. But at the same time, if you can spend an hour prepping the out put and save them days of head ache, definitely worth the effort.

@DangCad1 and  @Patrick M 

Are the DWGs being saved from the floor plan window in Archicad?

If so, then I am not surprised, as that is just a screen rotation you are seeing.

If the view is placed on a layout and then published as a DWG from there, does it have the correct rotation then?

I would expect that it would (again I have never tried this).

the layout will save to paper space with the correct rotation, but the x-ref still reflects a shift from the saved view rotation.
I try to avoid rotated views wherever possible, but some times designers either insist on rotating views, or project needs mandate it. In any case, dwg coordination has always been a sticking point; wether it's the absurd number of lines/fills on output, the tricky dwg translator hang ups... There has just never been a smooth or easy solution
