Up until ST10 MP3, STL files imported for use in Reverse Engineering did not need to be repaired. Starting with ST10 MP4, a lot of imported STL files for use in Reverse Engineering have geometry errors and need to be manually repaired using 'Heal Body Faults' inside the Geometry Inspector.
Solution Up until ST10 MP3 if there were any faults in a STL file those faults got repaired automatically during the import process. However, this automatic repair process impacts import performance. Starting with ST10 MP4, to improve import performance this automatic healing option has been disabled by default.
Starting with ST10 MP4 there is a new option, 'Heal mesh faults', in the SESTL.ini file. By default this option is set to OFF. This option can be set to either ON or OFF.
If this 'Heal mesh faults' option does not exist in your SESTL.ini file you can manually add the option and set it to either ON or OFF.
Setting this new option to ON will automatically repair the file during the import process.
If you set this option to OFF do not forget to use Geometry Inspector on your imported part files and search for any existing faults. Otherwise you might see the message "Failed to apply changes - Changes to some of the selected bodies were not applied due to internal error. These bodies are left intact." for most of the Reverse Engineering commands.
With Solid Edge 2019 this option will also be available in the UI 'Options' menu during the STL import process.
