Has anyone come across this issue? when DirectX hardware acceleration is enabled in options screen appears to have blind spots - certain elements at certain zoom levels and in certain places on the screen flicker and disappear. The bad thing is that those element will also be gone from the prints at certain scales which is a serious issue. I checked 3 different computers and they all had the same problem. They all had ATI video card so maybe this is connected. So far the only way around this issue I found is to disable hardware acceleration in options which defeats the purpose and make shadows painfully slow. I am not sure if this problem is limited only to files created in earlier versions of Revit and updated which could be the case. Attached is an example - a piece of a PDF file generated with DirectX acceleration on. I actually tried 4 different ATI cards w/ and w/o latest drivers in different machines - true they were all I think decent 3d gaming cards (radeon HD 4670, HD 2600xt, X1300/1550.. I forget the 4th one) I've read somewhere though that supposedly Revit doesn't quite take advantage of the professional CAD cards or something to that effect. I tried raster processing for plots too but it doesn't really help - only different elements disappear in different places. The only thing that works is to disable DirectX or keep on while working (flickering on screen is somewhat bearable) but make sure it's OFF for plotting (!).. otherwise the contractor will not price your missing door or whatever else might be missing.. Is there any better solution to that other than waiting around for Autodesk to release a service pack or a patch?

did you try updating the drivers for the ati cards? this is a usual fix when installing new software

as I said in my first post I did try new drivers - I wander if Nvidia cards would have the same issue but don't have any laying around to try..

I tried 2010 with the acceleration on my ati 2600pro. No problems for me. I could offer to look at your model on my computer if you wanted to email it but thats all I could do.

this is something that's hard to notice at first - I was blissfuly unaware of the problem for quite some time and it was not until a meeting I happily went to with a roll of drawings when my hair went up.. luckily it was still before anything was submitted for permints or bids... sections and elevations seem to be more vulnerable to this bug for some reason..

thanks lunch tray rider! ...another thing I noticed it that more elements are missing if I scale the prints - e.g. fit a 24x36 drawing into 11x17 paper.. beware!

Typhoon, everything worked just fine in earlier versions - it's the switch from OpenGL to DirectX in 2010 that seems to have messed things up a bit.. and it's only when you use hardware acceleration in options - otherwise you don't have to worry about anything...

Quick update - I just tried a roughly 3 or 4 year old system - XP (apparently important factor) with some ATI Radeon 9000 something series - Revit 2010 with hardware acceleration on and it worked ok. - no elements missing in plots.. go figure... someting with Vista.. no wonder.. OR a single core vs. 2-core processor althought I tried disabling one of the cores for Revit in task manager and it didn't do anything...

JCHE, what i'm trying to say is, I'm using dual core 2, 2.40ghz, 8 GB RAm, ATI Radeon x1600 512mb, with windows vista 64bits, since 2 years, in revit 2009 with OPENGL ON never had any problems, NOW with Revit 2010 with DIRECT3D ON, no problems at all, NOW about waht you said "Typhoon, everything worked just fine in earlier versions - it's the switch from OpenGL to DirectX in 2010 that seems to have messed things up a bit.. and it's only when you use hardware acceleration in options - otherwise you don't have to worry about anything..." - SO, read what i post, Vista 64, Revit 2010 with Direct3D ON and still with NO PROBLEMS AT ALL....

Happy for you Typhoon. I don't doubt that there are people out there with ATI cards and super duper systems that have no problems - I bet Autodesk didn't have problems testing 2010 either otherwise they would have addressed the issue. Sorry I may have missed something - I read your both posts and until your last one I had no idea you had 64bit Vista and DirectX on.. anyways I just happen to have a problem that is consitent on 3 computers and 4 different ATI cards - maybe it is the 32 v. 64 bit Vista question.. I have no clue - that's why I'm posting hoping someone had similar problem (obviously you don't - I know there is at least one person on AUGI that had it) and maybe found a solution other than disabling the damned thing.. cheers!

jche - can you post a better description of your hardware and software? im gusessing that your using a 9xx intel chipset with a something and vista either 64 or 32. 9xxx ati cards did directx 9.x hardware and typhoons also does 9.x hardware but neither his or mine does 10.x hardware. at least your 46xx card does 10.x directx hardware. Im guessing that there is a screw up in there somewhere as it is my understanding that revit 2010 uses directx 9.x. Im also guessing that typhoon has an intel 3x or 4x chipset. I have a 3x intel chipset. if that made any sense let me know.

hey lunchtrayrider, just installed Revit 2010 on my computer at home - here's a couple of dump files from my system - same thing unfortunately but again it's a similar setup - vista 32 bit, ati video - latest drivers, dual core, more in the attached files. let me know what you think, thanks!
