Is there a secret?
We can't get Autocad to function well in 3d mode. It freezes, crashes and stops responding.
We need some help. Any advice? Are we missing drivers, or other hardware?
I looked up 3dconfig and we have very little showing up as "not available".
If you have any suggestions, variables, hardware or otherwise that I can try It would be appreciated.
Other people here don't seem to be having a problem.

Can you provide the specs on your system?Originally Posted by darthyoga
Re: Is there a secret?
No.
I don't know what I have or don't have. If there is something that Im required to have to operate 3d please tell me all of it so I can email to the IT guy. I am ignorant of hardware and most things related to 3D on Vanilla cad
Re: Is there a secret?
Without knowing what you have, it's hard to make recommendations. It could be a memory issue - maybe you don't have enough. It could be your graphics card. Heck, it could just be that your processor is too slow, but without having that information, it's hard to tell what the problem is.
Your IT guy should be able to give you the specs of your system if you can't find them yourself.
Re: Is there a secret?
We have everything we need to use 3d. Our machines are up to date and we have all the RAM and GIG we need.
Autocad just can't handle what we need it too.
Is there a plug in or some sort of add on that will make our current system capable of handling 3d site layouts? ( small cities ) Or do we need to switch to an entirely diffierent program?
Re: Is there a secret?
Most of the current 3D Autodesk programs require 2GB RAM, a faster hard drive 10,000 rpm or higher has been recommended by many, dualcore or dual processors (the bigger the better) will improve regen speed and such based on WHIPTHREAD value, mine is set to 3. Also, a good Video Card 256 a minimum cross checked with Autodesk approved video card list.
Software items to try within the drawing:
purge
setting MAXACTVP lower - this will turn off some of your viewports.
Anti Virus Programs and other miscellaneous items running in the background can drain the processor.
Swapping space - let windows manage this automatically.
Hard drive space - If there is not enough room for the software to swap, this can bog things down and even cause crashing of software.
Keep in mind, too, some functions of ACAD do not clean up after themselves. If you find the length of time you work in a CAD session is proportionate with the slowing down of the drawing, close ACAD and start again.
It is difficult to pinpoint what your specific problem might be without the details of your system and setup. If there are others in your office without the problem, compare with them to find out why.
Re: Is there a secret?
Technically you can do what you want in AutoCAD which is why you are getting these curious questions.
1.) First we need to know the size of the typical file you are using with AutoCAD. A small city doesn't sound so small in terms of file size.
2.) The amount of RAM, processor speed, and type of Graphics Card are fairly vital questions. I understand you don't currently know, but these are the top 3 causes for the problems you mention.
3.) Drivers, etc could be an issue if you don't have the latest drivers available...but once again without knowing what your system has we can't really diagnose that.
Ultimately I doubt AutoCAD can't handle what you do as it is very good at handling models, I would make the hypothesis that your current hardware setup can't handle what you are asking AutoCAD to do. This could be an issue of your hardware not being powerful enough or not having the correct drivers to talk to your hardware or even AutoCAD not supporting specific hardware on your current system. The more information you can provide the more we'll be able to narrow our diagnosis down.

Intel® 3.0 GHz or greater
2 GB RAM or greater
2 GB free hard disk available
1280 x 1024 32-bit color video display adapter (True Color) 128 MB or greater, OpenGL®, or Direct3D® capable workstation class graphics card.
All of these are what we have. The file sizes are around 2000-5000 KB but are made up of 3D and 50 plus xrefs.
We are working with site plans that include machine details down to the nuts and bolts ( in 3d) as well as xrefs referencing survey and building layouts. We suspect the drawings were made in revit or solid edge or some other program.
The site plans would be like looking at a plan of a world exposition down to the smallest detail. I just don't think it can handle it.
Everybody in the office has this problem. Our 3d drafter works well up to a certain point ( drawing a transformer ) but as soon as the drawing gets complicated ( Putting a transformer into a site plan ) things start crashing. I can barely open the drawings, let alone plot, or look at them.

Re: Is there a secret?
2gb free HD space is recomended for basic CAD usage. based on your file descriptions you need 2 - 3 times that free usable as swap space for memory. 2gb ram is ok for files like that, but if you could go higher it wouldnt hurt. anything in your drawing that can be converted to a block and repeated should be. if you have doing several city blocks worth of a model and are going into detail on the level of nuts and bolts you have an insane amount of information in the file that the computer is trying to process all at once and it just cant physically handle the information.
unload (not detatch) any xref's that arent immediately required for work you are doing. that will free up a big chunk of resources to apply to other things. freeze layers instead of turning them off.
Re: Is there a secret?
Which is a great idea but these are client drawings that we are using. It's a matter of being able to manipulate these drawings ie, create backgrounds, xref, and use them as references. The time it takes to purge, flatten, or create blocks is tantamount to the time wasted trying to open and use them. Purge and flatten usually copp out afte half an hour if the machine doesn't entirely freeze up.I think we need to go 3D. I don't think the program was meant to take that kind of abuse. There have been talks but I really don't think Inventor will cut it.
Any other suggestions?
