Thanks Chris, I just had a look at that but it is huge (now 43MB file) and difficult to navigate. The "migrate" keeps generating bodies like "Clone043Body005. I created a part "X-Motor-end" using Part Design: X-Motor-end.jpg I then cloned this body and used the Part Mirror f...

Hi Chris,

Despite my efforts to remove the problem, I still get the error at times. What tools can I use to isolate and identify the problem(s) in the model?

thanks,

Ron

My first guess was better: The additive pipe and the revolution are features without body. The attached file was derived from your file: Snip macro screenshot-0069ed.png Even without this, your file was a pretty mess where I had difficulties to find my way through all the references going to and fr...

thank you in advance,

It seems that the file is now corrupt, because sketching seems to be broken. When I try to sketch a polyline in Sketch093, a red message "Solving sketch failed, Internal name Sketch093" comes up. Removing all constraints and reapplying seems to allow me to progress. I have uploaded the fil...

It happened again. The file is too large for the forum so I put it on my google drive here: https://drive.google.com/drive/folders/1xbttUb6v0xAhd8xR6TqxUZhKYxnudmol?usp=sharing I had just deleted some steps out of the model due to design changes, made the "Hotend-rocker001 active, and started t...

If I get it again, I will save a copy and upload. Thank you.

migrate.jpg I frequently get this error popping up. The document was not created in a prior version. Any suggestions about how to fix this? What additional info should I provide if it happens again (if any)? thank you Ron OS: Windows 10 Version 2004 Word size of OS: 64-bit Word size of FreeCAD: 64-...
