G'day Tasmart, sorry for not responding sooner. since i started this subject i had a dream run with revit simply because the stuff i was working on were all small files of about 20 mb. this week i got back to an older file of 160 mb and it did not take long to get into the muck knee deep. my dealer suggested i reduce my ram from 4 gb to 2 gb and to set my vrtual ram to 8 gb (4x the phisical ram) the machine still runs smoothly. but it did not stop my files from crashing so much so that i bit the bullet and exported the file to autocad and i iam finishing it of in autocad. i can not afford to be a hero any longer. it may be a hardware problem someone suggested to me, i should try a larger power supply, i got a 400 watt perhaps i should try 700 watts. is there a way to moniter power usage over a day or during a heavy task? what really gets me, is that revit (the way i understand it) will let you carry on with a corrupted file and the bakup file of the lastworking copy can allready be deleted at the time of you are actually crashing a file. i saw a message :"file was corrupted in previous session" or similar please correct me if i am wrong.) it is adviseable to keep on saving under a different name eg: fred 14-08-07 1500hrs. this way, your backups do not get wiped off. also export to dwg. regularly, only needed a plan view to finish the job and was able to finish in autocad i do not know what to do when elevation and sections are required save the model or the section and elevation views? i have a lot of large families in my projects and i learned that when editing these , one should not do a lot of these in one go and than open the project file, because if one of these became corrupt during editing the project file can crash and you do not know which onecoursed the crash . purge each one after editing, close and than open the family with an audit.then load into project. all very laborious. i found this out after a project crashed then i purged and audited the family opened the crashed file (not the recovery file) and it opened without crashing i would like some comments from some more experienced users. they might thing it is a lot of gobldygook. also i like to hear what the machine configurations are of people have which do jobs over 50 to 100mb and those that have jobs over 100mb i like working with revit and i hope that i can find a solution so that i can keep going on with it. cheers and good luck robert
