Tim Olson - is there a way to recover a damaged file? Just lost 2 days. When I quit V14 and re-opened, file and backups were damaged.

Attached here..

Any help appreciated.

How do you know that this file is damaged? Sometimes large files simply take a long time to open, and during this time, ViaCAD seems to be frozen. Check the task manager to see if the process has CPU activity.

*afaik* corrupted files (probably damaged by the undo function) cannot be recovered.

As always, do not save one (1) file only but, at least for important stuff, do a 'save as' by adding an incrementing version number "xyz.01.sfx" etc.

I know, doesn't help yet...

Hi timr,
Do you have Time Machine running on your Mac?
Maybe it have stored a backup you can use.

You are exactly correct. I just performed an UNDO on another model - saved, closed the file, it would not re-open - same damaged file message. Even with multiple copies I'm scared to close any file at the moment...

I get damaged files a lot even with v14. Finally, I reverted back to my old AutoCAD 2004 lt. However, I have been trying out the latest WIP and so far no damage files, fingers crossed. It did crash to desktop though yesterday when I tried to print something with Phong view. I could not get it to print until I changed it to polylines. Then it printed fine.

Today it kept crashing to desktop. I compacted the file, and that fixed it. I now save a new file about every 2 hours. Then I close the program and reopen it to make sure nothing is damaged.

I am glad to see the mirror function now works right, and the dimensions in viewports bug is now fixed. But damaged files especially damaged backups are the worst because you cannot recover anything.

Maybe this latest WIP is the trick. Sure hope so.

...
.


Can I mention another issue with phong views in 2D views format ?
It does not print to pdf unless the rendered view is fully displayed on the monitor.
- If the phong view is not fully visible it will not be complete in the pdf.
- If I do "view all" before, most of the time the pdf result is at very low resolution...

Keeping this thread on-topic:


Again, more damaged files and backup files on Shark V14. Even with saving versions 01, 02, 03 etc. Closing the file and or restarting damages the file.

THIS IS NOT A BETA - this software is for sale on PunchCAD right now.

the document already gets corrupted during modeling, saving the corrupt state to a file leads to the corrupt doucment finally.

Trying to undo a (complex) e.g. surface modeling operation by reverse calculating the previous state seems to be prone for the resulting geometry getting corrupt by design because of e.g. unavoidable rounding errors which do add up with every further undo.


save early, save often, and don't overwrite saves

If you open your CAD file in a text editor such as "TextEdit" scroll down to the last line and see the word "SUCCESS". If it is not there the file is bad.

Assuming the file is still open in your CAD program, look for unresolved links and fix them, or try compacting. Save again and see if you now get "SUCCESS". If you have multiple backups check to see if earlier ones were successful, if so consider what changes have been made since then to help resolve the issue.

The OP states that he overwrites saves instead of having incrementing version levels of the document, which was actually recommended by me.

So what you're saying is save hundreds of back ups just incase? Who has space/time for that? For arguments sake small files yes maybe, get something of a few hundred MB and you'll need a serious storage space to keep it all on the off chance it becomes corrupt! If you have a file of a hundred mb for example are you really going to sit there clear the resolve errors, clean then part, save the part, wait for it to save, go check it's saved ok. If not then somehow get a stp out of it before you get a crash or something? Then start again?
It would be better to find why they become corrupt. I started using v8 of this software and not once did I experience a corrupt file, v9 and 10 again not once was there a corrupt file in the years of using them.
V11 and 12 it was almost every job I did it became corrupt. Something happened, and it should be found and fixed.
I've had back up files which saved fine and opened fine suddenly not open. I checked whether it was network saving or local saving that did it, nothing made a difference. In the end I gave up......

Anecdotal comment:
How does creating a backup even help, if the corruption happens upon Save or SaveAs ?
Would that process be to do an 'open' test of the file, and if that works you create a bkup before making more edits?
But then you have issue of big edits. Example, you have a good backup, you open the file but then make hours worth of edits, Save, and now corrupt. The last bkup made is still good, but now you lost hours of new work.

From my experience, there is no round-about solution to a program that constantly corrupts files, the issue becomes lost work hours. In other words, not good.

And what do we learn from this? All versions after V9 Build 1162 are a complete waste of money.

I do in general recommend saving revisions of at least important documents from time to time sothat you can go back to a working document before losing everything but also allows to go back to a document without unwanted changes of the last session. But hey, you're free to save to one and the same document only and just wait for Tim fixing the issue... which will probably never happen if e.g. related to the used ACIS kernel.

Storage space? ...you're surely kiddin'

If the Save or Save-As kept a history file of the commands done, you then technically do not need countless revisions saved. A history "manifest" where such feature allows you to record a user selected number, like last 20 or 100 edits made. I know there's that Deep Select tool that allows you to remove something like a fillet, but just need a history for the Undo feature, etc.

No I'm not kidding. Not everyone has an online storage or massive hard drives to store data. Especially if they are perhaps starting out and haven't yet invested in anything yet.
