https://forums.autodesk.com/t5/autocad-forum/block-editor-crashing/m-p/7220834#M312173 <P>I am having a very similar problem, sorry I cannot be of help. But I just lost about 4 hours worth of work done in the block editor, of a fairly complex block that I have been working on. I saved the definition several times while in the block editor, I never exited the BE to save the drawing, and it froze up and I had no choice but to do an&nbsp;<EM>end task</EM> through task manager. I am using AutoCAD Mechanical 2016. I'm hoping that someone out there has some advice on how to recover my lost block. When the drawing recovery came up, it only had options to open the drawing that i saved 4 hours prior to the crash. I have my auto save set to 5 mins. And as I said earlier, I saved the definition several times in the editor itself, but never inside the actual drawing area. I would really like the developers of AutoCAD to&nbsp;<STRONG><EM><U>QUIT</U></EM></STRONG> putting unnecessary&nbsp;<EM>"new"&nbsp;</EM>features into the program and perfect the ones already available. I feel that I am the only one on the planet that despises the stupid ribbon! lol. Anyway,&nbsp;<STRONG><EM><U>ANY</U></EM></STRONG> help would be greatly appreciated!&nbsp;</P><P>&nbsp;</P><P>Thanks.</P> Tue, 11 Jul 2017 22:26:57 GMT Anonymous 2017-07-11T22:26:57Z
