Error Message with Iges files

[James]

I am running Windows 2000 Pro, a new pc, and the latest version of MasterCam. When I import an IGES file I get the message " Mill8.exe has generated errors and will be closed by Windows". If I get lucky and it reads the file I will get the same message when I try to save the file.

After two days of my Mastercam Dealer and myself trying all kinds of things we still have not fixed the problem.

Can someone please help?

Thanks,

James

have you tried playing with the video card.

try adjusting the hardware acceleration down a few notchs and try again.

I get the same error randomly throughout Mastercam. I have re-registered the .ocx files per tech supports suggestions. This has reduced it but not eliminated it. I have turned the hardware acceleration down to zero. Only reduced it.

[James]

I played around with the acceleration and I still have the problem. It didnt seem to make any difference.

Thanks,

Have you tried installing the latest iges in patch.

I don't know if it will help but for sure wont hurt.

My system had a ATI Radeon 7500 64MBddr video board in it. After I did everything anyone could think of I removed the ATI board and installed an older NVIDIA TNT2 Pro board. All of my problems are gone. I get no error messages and everthing runs fine.

Thanks to all for your suggestions!

What is the link between the graphics card and reading in IGES files?

I'm willing to take a look at the IGES file for you. I'm even more curious than you are as to why the graphics card makes a difference. If you can. please E-Mail it to [email protected].

Thanks

I have had a simliar problem with that graphics card (ATI Radeon 7500 64MBddr)in Win2000 except is was when using solids. Put in a different card and problem is gone.

[James]

I know changing the card fixed my problem. What is the relationship between the graphics card and crashing when I read an IGES file in?

Thanks,

James

James,

I started to say, all ATI cards are suspect because of the very nature of the chipset. ATI makes Entertainment cards for standard Home Consumers in the computer market. They have been known to have BUGS for engineering application software. ATI doesn't care because that's not their market. We recommend to anyone who buys a new computer to use only video cards which have mature, OPEN GL support and drivers. You can find some input about components which work well with Mastercam in the Info section of this website.

I had one of our Mill3 systems here mess up and found that turning the open GL off fixed everything. This system had NT4 sp6. I run Win98 with an ATI Rage 32 MB and had no problems after installing DirectX 7.0a and the latest ATI drivers.
