Recently I have downloaded some files for cribbage boards from Cutrocket.com. The files are fine but the original creator used custom tools. When the files were opened in CC the tool paths showed the custom tools for some tool paths. I did not pay much attention and loaded one of the files up and it immediately asked for a tool that was not in the .c2d file I think because I did not have the custom tool used in the file in my tools.
The point is not to gripe about CC but to warn if you download a file from someone else go through each tool path and make sure you have the tool listed and edit the file to put your own tools in.
I did buy a file from etsy.com that had a v8 cribbage file and it is a very nice file but was full of custom tools. I opened each tool path and put my own tools in. Saved the file and am currently cutting the file.
Will report back when done.
