We have just built a Win7 x64 workstation. i7, 8gb RAM, 500gb HD, I do not remember the video card since it was last weeek when I deployed. But we are using AutoCAD MEP 2010 with SP2. We have problems such as not being able to adjust elevations, select pipe styles and such that are not a problem in 32-bit version. ANd it will not let us start with a specific style to start piping. I am not at all happy with it so far. It runs lightning fast but if it won't do what you need it can be slower than molasses . Either way it is useless to use. More data as I run into it.
THANK YOU FOR YOUR REPLY,
We have heard way too much bad about MEP 2010 and are completely skipping that version, we need the lightening fast but we do need the software to do what we need it to do, check your video card and see what driver you are using we had recently downloaded an approved AutoCAD driver from the NVIDIA site and it started degrading our computers almost instantly I caught it the first day as a result of my co worker stating he had done it 2 weeks previously and had been experiencing severe problems so I promptly re set the driver back after doing a system restore and all is well with that part so watch what driver you install, but post as you find problems. We spoke at length with AutoCAD for some of our issues and the gist of the conversation was we corrected that in the 2010 version (but it has numerous problems as well after doing a bit of research) so I just hope by having this Message out here that someone will touch on a solution allowing us to take full advantage of the software and have it work with minimal problems, we like all the advantages it has but when we constantly have to re set links and circuit info just vanishes our old way is much faster (and it was slow) but going back and re-doing the work you have just finished is even slower!!!
This is our first foray into the x64 world. We are also running C3D but it is a 32-bit software running in a 64-bit environment. Here is the info on what machine we are using for the x64 MEP. We are not using the AUtodesk approved drivers and form what I have read so far and really, really glad.
