Raster modifications reappearing after saving.

[Anonymous]

Pulling my hair out with this one.

I am inserting Tiff  files as Raster images, and then imbedding them.

I am then working on them by adding parts to the drawing and removing existing parts.

then I save the changes shut down the dwg file, when I reopen it, my autocad additions are there but all the rastering removals have reapeared back to before I removed them.

the only way I can get them to save is by shutting down autocad and restarting. this will let me save for a while. before repeating the same process of the raster image work not removing.  

repeat the shut down of autocad and reload.  again a small window of work before it plays up.

this is at work and I have had a few people look but we are all unsure why.

I have uninstalled autocad and raster and reinstalled them, but to no avail.

Has anyone come across this? if so help!!!!!!

I haven't seen this before as I don't embed images, but I would try this. Leave the image as referenced, make your changes and then embed when you are all done making changes.

It's worth a try,

I am new in my office just after training and I am following what everyone else is doing, I can mention if this is an option.

Thanks.

  I saved, closed and re-opened.  When opened, the image is not what I edited but is back to its original image.  How do I get me edited image back?

Ok I have found a solution to this. Most other people in my office don't do it this way but it works for me and I was having the problem.

So most people are clicking the quick save option at the top to save their work. This did not work for me. 

What I am having to do is, while in the raster tab once I have made my changes. On the far left side There is an insert and write ribbon. Within this ribbon there is a save image option. When I click on this it seems to save the rastering work I have done. I then always finish with a quick save just to save any non rastering work I have done over the top.

I hope this helps for anyone else having this problem. Finally my hair can start to grow back in.

That's the way you're supposed to do it. You have two different files, vector dwg and raster. QSAVE saves the AutoCAD dwg and ISAVE saves to the raster image. If you try to close a dwg with a raster image that has changes made, it will prompt you to save, but it uses the ISAVE command to do it. If others were only using QSAVE, then they were not making changes to the raster image.

Hey,

I think this is an AutoCAD bug they should fix. There needs to be a check for unsaved raster modifications before allowing the user to close the .dwg file. I raised a ticket about this with AutoCAD who did not really understand the issue.

i.e. at present, you can modify raster content in an embedded image, then click the normal QSAVE and close the file, not saving the mods to the embedded raster. This is very easy for users to lose work as there is no warning or reminder from AutoCAD.

Thank you denisd75 for pointing the solution! 

It is definitely a bug because most of the users saves the file with Crtl+S (SAVE command) in our office and it works for everyone else but me. I have to do it with ISAVE first and then SAVE.

@joonas.salmi It's not a bug, see my post above. ISAVE stands for Image Save. Qsave means Quick Save and only saves a dwg. Dwg's don't normally have raster images attached. If you have Raster Design installed, you can edit an attached raster image file and so it handles image saves. AutoCAD can't do that and so it doesn't have any means to save changes to an image. It wouldn't make sense for it to do so.
