Save operation failed - post step file import

[scot0511]

Guys,

Get an error message when attempting to save a CATIA V5 file post STEP import. Error message "SAVE OPERATION FAILED PROBLEM WHILE WRITING FILE".

Version 5 Release 16 SP4
Win XP SP2 Professional
Liscense avaiable : ST1 + others. [only step license shown]

Import STEP file [134MB size] ok
Go to save CATIA V5 data, File -> save
error message appears "SAVE OPERATION FAILED PROBLEM WHILE WRITING FILE".

Has anybody a suggestion?

Run CATDUAV5 utility after import (you can find it in C:\Program Files\Dassault Systemes\B16\intel_a\code\bin\CATDUAV5.exe Maybe this will fix your problem.

V5 can not save a file larger than 132MB. It will let you create & work with it, just nor save it. You'll have to split the part into two files. I had problem quite often when converting V4 data in the past.

I have converted larger files than 132mb (666mb) but I used 64bit version of CATIA so there was more than enough process memory available.

I just tested a 186mb step file on a 32bit system running R16 Sp6 - XP SP2. Everything appears to be there.

basspaul2 - some of our files range from 150 - 250 mb.
what config of catia and hardware are you running?

This is totally untrue. I have over a hundred files in my directory to prove this false.

I've seen this in R12 & R14. It may be 150MB instead of 132, but there is a limit. It may be resolved r15 +, i'm stuck with R14 for customer reasons

It may be 150MB instead of 132

I have R14 files that go over 200MB. My understanding has always been that the limits are not on the file size, per se, but on the *process* being utilized by Catia. (of which the file constitutes a portion)

I have no idea what the maximum size is on Catia processes.

[PeterGuy]

maximum process size is an os limit
2gb on w2k & wxp
3gb on wxp +3gb switch
4gb 32bit catia on wxp64
lots and lots 64bit catia on wxp64

Any program no matter how cheap or expensive will allways stop working if you run it out of memory address space.

This is negative - tried desk -> CATDUAV5. Nothing

This is on a 32bit system windows xp sp2, catia v5 r16 sp4.

Is this "maximum process memory" down to RAM on machine and the virtual memory settings within CATIA V5?

 

[PeterGuy]

Maximum process memory has very little to do with physical or virtual memory.

Maximum process memory is a limitation of architecture an nothing else (below is a simplified explanation it is not entirely accurate but it will do for the purposes of illustration)
eg 2^32 = 4294967296 (4gb) this the absolute maximum address space available to a 32bit system. Evey process that is started (CATIA, Word...) is allocated 2gb of address space. There is an overhead for the operating system which accounts for remaining 2gb of addresses, hence the 2gb limit.

If every process that starts can use 2gb of addresses it is easy to see that this very quickly exceeds the physical ram of the pc & this is where virtual memory comes in, it is a store of the data that will not fit in to physical ram.

Adding more physical ram will speed things up because it is having to write less data to disk (at least 10x slower than ram) but it will not change the process limit. Increasing the virtual memory/page file will increase the number of applications that you can have running using their full 2gb address space but again will not change the the process limit. The only way to change the process limit is to use the 3gb switch or move to a 64bit os

In this case, maybe you can find here something

This link takes me to text titled "Identify and fix the unusual lost delayed-write data error" ! ? ! ! ?

Can you explain?

Thanks for confirming this - when you mentioned processor memory my gut feeling was this 3GB switch.

On that page you can find some explanation about Win OS problems during saving. I think your problem its not the CATPart itself. Maybe something with saving area.
