Perspective representation inaccurate

[Mel]

Has anyone experienced perspective views not representing correctly, i.e. walls becoming transparent, window families not showing, roof edge conditions not showing right (see attached image)

However, when creating a 3D view in the same project all elements are represented correctly.

I've purged and audited the file.
Recreated the central file.
Recreated the views - still does it on new views

The file is workshared, has phasing and design options within it.

File, currently sitting at 90Mb.

All help and suggestions appreciated.

Yes, we had similar problems, when we combined huge dwg 3d file with 3dfaces a revit perspectives. So we did Revit perspectives without dwg and then we used Photoshop to put all together. If you have there in your project some dwg files, try to remove (detach) them and see if some progress happens. And also sometimes WorkSets and Design Options doesn't like together in one project.

Thanks - as part of my troubleshooting I grouped and saved out all model elements and opened in a clean template, problem still remained. Will check that no dwgs went in that group etc

are your video drivers up-to-date, or at least an autodesk certified driver?

Are there any Linked RVT files? 2012 has a known issue with perspectives of models that have links. There is a workaround for it. if you file a Support Request, they might help you out.

Thats assuming you have Links in the file somewhere. (It doesnt have to be the links that are looking screwy).

It does appear to be due to our Graphics Video drivers being new than those 'certified' by Autodesk...Once hardware acceleration is turned off the file appears to be ok.
