Old CC Files Not Working

[circsaw (Teddy)]

So…is it just me or is it known that Files I created with CC back in 2020 no longer seem to work with the latest CC?

There have been some updates, and these posts provide a clearer explanation than a lengthy description from me.

C2d file not opening in latest build of Carbide Create

I have a c2d file created in build 652 of Carbide Create. It opens correctly in that version, but when I try opening the same file in the latest build (813) only a blank document appears. I tried drag/drop as well as File/Open… but the document contents appears to be ignored on load. Is the new version not backwards compatible with older c2d files?

How to convert a v7 3D file to v8

As noted at: https://carbide3d.com/blog/create-v8/ from “Breaking Changes” Files from prior versions will not load 3D components in V8. There were too many changes to the internal format for the new capabilities of 3D, and there was no good way to map existing 3D components into V8. so v7 files will need to be converted so as to use them in v8. Fortunately, Carbide Create has a feature for exporting the 3D model as a height/depth map pixel image: [image] so do that to get: [rams] Th…

Hey thanks @Woodcrafter I really appreciate it.

Short version

• If you are using Ver 8, everything 3D in previous versions is gone. Best you can do is use an older version to export a heightmap and rebuild your project from there.
• Ver 8 will open Ver 7 files.
• For Ver 6 files, open and resave in Ver 7, then re-open in Ver 8 and save.

I’ve never really gotten into anything 3d so I guess all my stuff was just basic flat designs in v7, but I’m getting blank pages when I try to open in v8

you know what, I really cant tell what version the file is, it’s not like I wrote it in the file name, but I can see the dates were back in 2020…I wonder if those are actually version 6 files?

[WillAdams (William Adams (Carbide 3D))]

You can check them in a text editor — if they are JSON code, then they are v6.

Or, just open in v7, resave w _v7 added to the filename, then open that file in v8.

ok, I got one open in Notepad, whats a good Find/Search I could use to see the version? I already tried “version” and nothing came up

[WillAdams (William Adams (Carbide 3D))]

If it looks like:

it’s v6 or earlier.

The line to look for is something like to:

        "build_num": 652,

@WillAdams

"build_num":

Looks like this

[mhotchin (Michael Hotchin)]

That’s a GCode file, not a CC project file.

[circsaw (Teddy)]

interesting. All I did was right click on the NC file and chose to open with Notepad, so I’m not sure what’s going on, but it was definitely saves and created with CC and CM as that’s all I’ve ever had lol

[circsaw (Teddy)]

Ok I found this in a file “build_num”: 464 super old huh?
