Revit Export to CAD produce wrong Coordinates

Revit file export to cad wrong coordinates while I linked with the correct Auto cad file.
but when I export to auto cad or any other extensions get wrong coordinates.
I used Enhanced DWG Exporter Features but, it was exported with wrong coordinates too.
what can I do?

check these options before exporting.

thank for your response, I tried this solution but I have the same issue.

Hi,

Don't know about "Enhanced DWG Exporter Features".

But does Revit itself report the correct coordinates when using a spot coordinate tag, so to know Revit coordinates itself are correct.? Take a know coordinate point and place a Spot coordinate there (with correct setting Survey Point/Project point)

Also do you export a View or Sheet, Sheet export can be different. If you need specific coordinates export the view itself.

are you using the same units on both software?

can you share your files?

[mohamed.elzaghal]

it is the sample one from the AutoCAD file , which is coordinate system is Egypt redbelt 

when I draw wall on this box and export it to cad , I get wrong coordinates and scale.

[mohamed.elzaghal]

it is the sample parcel with Egypt red belt coordinate system.

when I linked it to Revit and draw wall or ay thing in this parcel and export it again to Autocad extension. 

I get wrong coordinates and scale.

i see.. 

when you link the CAD the first time, did you select the right units? and then you MUST acquire the coordinate from the CAD. If those steps are not done, you wont be able to export and get the same coordinates.

i select the right units from AutoCAD and Revit,  MUST acquire the coordinate from the CAD. 

but I still have an issue for exporting file to Autocad it has a wrong coordinate system and not in scale.
