Autocad 2012 64 bit

[Grumpy]

I also have a new computer with Windows 7 64-bit.

a Dell T7500, 12 GB Ram, 6-core, Intel Xeon X5650, 2.67 GHz with an nVidia Quadro graphics card.

AutoCAD 2012, 64-bit is installed. I have had a few crashes, that I attribute to the Drawing Tab utility. But what I find odd is that there are some commands that this "Fast" machine takes a long time to process. Inserting a block from a Tool Palette takes several seconds, where before it was almost instantaneous. The other one was I had a 3D solid that I had imported from Solidworks and I ran the Flatshot command on it and it took literally 30 minutes to finish it. In AutoCAD 2012, 32-bit on WinXP Pro it would take 10-15 minutes, but half the time I couldn't continue working very long otherwise the computer would crash, but with Win7 it doesn't crash, it just takes a long time.

Check you Incremental Save Percentage - help file info below

Sets the percentage of potentially wasted space in a drawing file. Full saves eliminate wasted space. Incremental saves are faster but they increase the size of your drawing. If you set Incremental Save Percentage to 0, every save is a full save. For optimum performance, set the value to 50. If hard disk space becomes an issue, set the value to 25. If you set the value to 20 or less, performance of the SAVE and SAVEAS commands slows significantly. (ISAVEPERCENT system variable)

YMMV -- but today it makes no sense to me to worry about incremental saves. We're not running on DOS in 640K Ram, and we're not running with MFM hard drives or 4 Mbit star topolgy networks. The additional time required to do a full save is too small to notice or care about. Set ISAVEPERCENT to 0, and leave it at that.

I'm with cadtag.
I've always set ISAVEPERCENT to zero; at first other values sometimes caused problems, now it's just irrelevant.
