Anyone else occasionally have a complex mesh be damaged (usually just a few very tiny triangles are missing) by closing and opening a file. This has happened to me a few times now. I know the mesh is fine because I run Solid Inspector on it and export a working .stl file. Then I close the file and open sometime later and find the mesh is damaged.
Check your scale, too small will fail in SU.
Uncheck the checkbox in the preferences (General tab): “Automatically fix problems when they are found”.
Leave the checkbox “Automatically check models for problems” checked to see that there are problems and try to repair them in a backup copy of your file (without auto repair!).
Thanks. Always a good reminder.
Thanks. Will give that a try.
Fred :Post the model if allowed. Some times one finds the SU mesh is not pure even though it will report ok. Would like to run checks independent of SU.
