iMac i7 Intel Render Problem?

[APE Design Ctr]

I bought 2 brand new iMacs with the new i7 processors.

Both have two identical problems:

- I have a fairly large drawing (but not huge) with much 3D geometry. When I update viewports, I get either a crash, or an error that says 'viewport cannot be rendered because of lack of memory'. 'reduce the page dpi.

However the dpi is only 200, plus I have 12 gigs of RAM.

I have an old MacBook Pro with only 4 gigs of RAM, and it renders fine.

Both iMacs have identical problems. I also have a 2 month old iMac with the i5 chip, and it works just fine.

Anybody else having rendering issues with the i7?

Thanks all.

I have no problem rendering with my iMac i7 processors. I wonder if it is your version of VW?

[grant_PD]

the amount of ram is not going to make any difference, as VW can only get it's hand on so much of it anyway. Is there a setting in the system preference that is different between the macs on virtual memory, ram allocation for programs, page file, etc?

Aloha, Grant:

I don't think you can allocate memory for applications in MacOS X.

There are few things that can be done:

1. Run "permission repair" from Disk utility

2. Do the disk repair after safe boot.

Thanks all. I will continue to do some experimenting. Strange though - they are brand new uncluttered machines.

Using VectorWorks 2010.

I have a 27" iMac i7 (2009 version but bought recently), 4G RAM and I am not experiencing any 3D rendering issues. I mostly use final RW (not OpenGL)

Domer1322,

am I able to send a file to you to see if your VW2010 will crack?

Thanks

I guess I'll try and help .. send your file to rocket1322@yahoo.com ..... but I think yahoo restricts file size to 5 Meg. If your file breaks my iMac, can I get some free playground equipment from you ?
