Our office is currently working on a 4 storey building in Revit. I am having trouble rendering on any of the computers in our office. One of the computers having problems is a P4 3.6 with 2 gig ram and 8 gig page file, plenty of free hard drive space, and a powerful video card. When trying to render there are three things that can happen, after pressing "go!" the computer spends about 15 minutes processing voxel space and screen space then it will just stop the rendering without any notification and go back to modify on the left hand menu. I have tried a region raytrace of the building and it does the same thing. Sometimes after finishing processing voxel space and screen space revit will just suddenly exit without any warnings or error messages. Another problem is that it when rendering starts (or just when a camera view is opened) it will say "there was an error drawing the current window, the window will now close" or something along those lines. I have managed to get a couple of my views rendered by turning the view to coarse detail, turning the radiosity and raytrace quality to medium, turning off the furnishings inside the building (beds and such). And even with these settings it sometimes has the same errors. Does anyone have any suggestions to help me out? Should I switch to rendering with viz or 3ds max? Do I need like 8 gig or ram or something? If you need more info about the problem just ask me please. The project file itself is only about 24 megs, and at times while trying to render the task manager shows revit using over a gig of memory.
Just as a side note, redrawing any of these views takes about 30 seconds and it seems to happen way more often that it should have to.
Wow this is a long post, well if you make it to the end please write me back any advice you have.
Cheers!

Hi Joe,
Sounds to me like you could be having a hardware confliction problem.
I find revit to be a pig if the hardware setup is not right or if you vidcard 3d settings are not right.
Firstly, In my opinion the best rig for Revit is the following.
-dual xeon hyperthreaded chips
-maxed ram
-ATI technologies fire GL vidcard
watch renderings turn on like a switch with a rig like this.
hella expensive...but i say buy it today
Secondly adjust you current vidcard configuration to take advantage of any open GL options it may have..this is essential.
Lastly when rendering turn off all non-visible elements ie interior walls, fixtures etc
what kind of card do you have currently?
good luck

Hey Rubix.
The video card in the main computer is the Radeon x600 pro, its a pretty good video card and we haven't had any other problems with it. I have tried the rendering on 4 computers in our office and have had similar errors on all of them so I dont see how they could all have hardware conflics.
Cheers!

Do you try some other model to render. Render some of backup files.
I had similar problem with radiosity but only ray trace was fine.
Before in some orther program for render problem always was bed memory.

Hey guys,
I have had some luck getting this problem down. One things which seems to have helped a lot is to turn off the shadows in my rendering views (and use scene shadow settings for rendering instead of view settings). And turning off OpenGL seems to have fixed the "error drawing the current window" problem on one computer at least. I still have some tweaking to try on the settings but at least im making some headway.
Thanks!
