Display issue with Revit 2014?

[simon.bannister]

Hi,

I've got an issue with my Revit in that model elements are seeming to jump around all over the place as I zoom in and out - and never look right. Please see the attached screenshot showing what should be some circular contig piles in plan. The whole model is like this - I've struggled through so far for a day or so as I can snap to the elements and just about get things in the right place, but it's getting too frustrating now! I've seen this kind of thing before with linked in CAD files - which I normally strip right down to just lines, text, circles etc with no blocks, XRefs, hatch patterns, polylines, solids or anything too complex for Revit to handle but this is the first time I've seen it affect model elements in the Revit model as well. Does anyone know what's causing this? And if so, what can I do about it? I've tried updating graphics card driver (NVidia Quadro K600 - a bit old, I know, but should be OK) turning off hardware acceleration, but have had no improvement so far...

As always, any help will be gratefully received.

Simon.

This sounds like a graphics card issue to me.
What are your computer specs?
Did you try enabling the 3G Switch?
Do you have the latest drivers for the graphics card?
How much cache memory do you have available?
Revit tends to be very cache hungry so closing it down at lunch time and reopening later when you come back helps clear the cache.
