REVIT 2010 intellizoom issue

[bulletproofdesign]

Hey all.

I recently installed REVIT Architecture 2010 to see how it performs. I like alot of the new functionality. I have however encountered a problem, and was wondering if anyone else had encountered the same?

Here Goes:
After using 2010 for 1/2-1 hour I notice a huge reduction in responsiveness when changing zoom level. Either mouse wheel or 'zoom region'. Panning and rotating (in 3D) are fine and as responsive as usual.

I have noticed that the cpu usage of 'Revit.exe' also goes up at this time. If I close the program and reopen it, voila, back to normal. As anyone who has installed 2010 knows, this takes time...

Has anyone else encountered this problem? I would love to find a way around it as it makes REVIT unusable for me.

Cheers in advance.

P.S. This happens in both XP pro 64bit and Vista Home 32bit. Also tested with hardware accelleration on and off in both scenarios.

Hi BPD.

There is no definitive answer for this condition at this time.
It seems to have happened on 32 bit and 64 bit systems, with every possible video card type, size and generation, with re-configured VM (for those 32 bitters) with or without the 3Gb switch enabled (again for the 32 bitters) and does not seem to mind if it is a Core 2 Duo or a Quad cpu or multiple quads.

Also trying a range of video drivers is no guarantee of success - I tried 4 and none made any difference, yet others have had some success with the latest or the oldest.....go figure. I suppose that having the video driver for your card that AutoDesk advises running, is some possibility of reducing the possibles.


The general belief on the forum seems to be that it is a memory leak module in Revit (video memory seemingly).
AD are aware about it of course (how could they not be ?) and we all expect that it will have been repaired after installing 2010-WU-1 from July 06 ?

For sure, if it is not fixed, Revit 2010 will continue to be a total PIA for many and yeah,. as you say (and I have experienced) Revit is unusable.
Have you checked all of the running commentary here for other clues ?
(for instance, I had the QAT below the ribbon in its default position, and had 4.5 weeks of constant crashing on average, every 30 minutes. Seeing another post I moved the QAT to be above the ribbon and the crashing all but stopped immediately - although there have been a few since, but not as before).

I assume you have also tried Direct 3D video hardware acceleration on and off, as well as the aliasing check box on/off for general troubleshooting in the Rendering tab of Options ?

In only a couple of days WU-1 is said to be due so hang on and take a risk, the WU-1, is not worse than the original build ! (ha haaa)

Thanks for the Reply!!

I have been waiting for 'confirmation' from my reseller that this is an issue.... Um.... No biggy!
Yep, I tried many configurations and decided that it was broken (RAC2010 that is) I generally tend to turn off all effects i.e. anti aliasing as I prefer performance, not pretty pictures!

Good to know that AD are aware of this one, as it blows! Some very nice innovation in 2010, shame thay had to break so much to get it!.

Peace,

BPD

Could the slowdown over a period be due to the cacheing of all the views by the 'rewind' feature of the Steering Wheel?

As far as I can see the view history just keeps growing for as long as the View is open...

/later..
Hmm, no - it seems to clear if you use the steering wheel zoom - it is zooming using the mouse wheel that generates lots of rewind images...

Nice thought.

I will test this today. I do generally keep as few views as posible open whilst working, as I prefer power and speed over pretty and slow...

Will post my findings. I do however think this is an Autodesk issue, similar to the identical type problem with the release of 2009. http://forums.augi.com/showthread.php?t=83382

:sigh:

2010 DOA....

Hi William,

I agree with that in that the more windows you have open, the bigger the file.
However, I tried to open a 70Mb file yesterday and Revit hated it...slow as a dog, 30 second regen times like my old computer used to do 2 years ago.......(however it could be the way the file was created, or it might have nothing to do with that !!).

In general, my practice is to use the keyboard shortcut "CH" close hidden windows and ctrl S regularly to help a little to keep things down. Still, RA 2009 WU-3 on had none of these problems so its 2010 that is the problem !!

I don't use the navigation wheel at all, the cube a little and so I think this is a general "windows that are open add bulk" issue as above...being its not only the navwheel at fault.
cheers

Well the problem is not as bad as I thought, yet worse than it could be!

I generally keep my overheads low, and am forever telling my colleagues who complain about low performance to close the 15 windows behind the one they are working in.

Rewind history has no impact. When you close a view the rewind data is cleared, well it does not seem accessible once a window is reopened. I have also tried 'rewinding' to the beginning, then changing zoom (to remove the redo's) to no avail. Once the visual performance drops, it stays dropped. This was the worse news.

The good news, is that you don't need to close the Revit application. Closing and reopening the file seems to reset the display performance.

Peace
