dumfatnhappy Posted January 7, 2009 Posted January 7, 2009 ok, this has *never* happened before, I'm talking about a very small model too. Anyone explain how to do this? F1 was no help Command: hide Regenerating model. Command: plot Specify window for printing Specify first corner: Specify opposite corner: Not enough free RAM for HIDE--some lines will be hidden incorrectly. To increase available free RAM, set ACADFREERAM to a larger value. Command: *Cancel* Command: Specify opposite corner: Command: Specify opposite corner: Command: *Cancel* Command: regen Regenerating model. Command: acadfreeram Unknown command "ACADFREERAM". Press F1 for help. Quote
Dipali Posted January 7, 2009 Posted January 7, 2009 that is unknown command. After reading about memory in plot, I guess if the 'hide papersapce objects' is ticked in plot dialoguebox, untick it & retry the ploting Quote
ReMark Posted January 7, 2009 Posted January 7, 2009 It's a memory management tool leftover from the good old DOS days. ACADFREERAM, LISPHEAP and LISPSTACK values were all set in the Autoexec.bat (bat = batch) file. The other alternative was to use a memory management program such as QEMM to handle everything which is what smart users did. You're running Windows, as most of us are, and therefore you will not have an Autoexec.bat file or, for that matter either, a Config.sys file. AutoCAD no longer recognizes the command now that it is Windows compliant. Quote
ReMark Posted January 7, 2009 Posted January 7, 2009 Turn off some of your background programs (antivirus or email) and see if that helps. If it doesn't then you'll have to try stopping one or two of the processes that Windows runs in the background. Do this by way of Task Manager. Be careful which processes you disable. As a last resort you might get some relief by using a memory flushing program that reclaims unused but temporarily retained memory locations. Quote

dumfatnhappy Posted January 7, 2009 Author Posted January 7, 2009 yer killin me Remark.......kinda dating yourself there aren't you? I was xtree gold myself after using an unkown called pathfinder first. The thing is, I'm using 64 bit with 8 gig of ram on a TINY model.... (compared to the 30meg with no issues) granted I have maybe 5 other drawings open (but all small) sumpthin is up me Quote
ReMark Posted January 7, 2009 Posted January 7, 2009 Free up memory with this little utility: http://www.allworldsoft.com/keywords/date/elite+freeram/ RAM Booster is another one that I used to use back in the days of Windows 3.1 and Windows 95. Quote

dumfatnhappy Posted January 7, 2009 Author Posted January 7, 2009 This might be of some help: http://discussion.autodesk.com/forums/thread.jspa?threadID=93739 actually none of it did (but I still thank you for it) I was plotting to a PDF for starters....I changed those values it mentioned and still no joy. funny thing is, it eventually does plot even though the screen goes black (model space) where not even a regen will bring it back... I have to literally exit the drawing and re-open it . strange Quote
ReMark Posted January 7, 2009 Posted January 7, 2009 A look back in time. Paraphrased from AutoLISP in Plain English, 3rd Edition by George O. Head. LISPHEAP was the main storage memory used by AutoLISP. LISPSTACK was the working memory used by AutoLISP for such things as nesting IF statements. The two settings read only by AutoCAD and AutoLISP reserved memory. If you failed to set these you'd get the error message insufficient node space. ACADFREERAM allowed you to set as much free RAM area as was available for AutoCAD. If you failed to set this you'd get an out of RAM error in AutoCAD. All these settings were added to the AUTOEXEC.BAT file. And that's today's trip down memory lane. Now, how's that for a pun? Pretty clever, right? Quote
