## Feature history
- **Native tree detected files:** 4878
- **Files with decoded modeling or sketch steps:** 4726
- **Recorded native features:** 188181
- **Decoded features:** 182159
- **Decoded modeling and sketch steps:** 46746
- **Analysis recovery:**
  - **Decoded without recorded history gaps:** 509
  - **Partially decoded:** 4369
  - **Meaning:** These counts describe automated analysis of the saved feature tree. They do not measure whether the native file can be edited in SolidWorks or prove that every feature and sketch constraint can be rebuilt by another tool.
- **Feature type counting method:** Non-exclusive counts of files containing at least one decoded feature of each type. Occurrences count individual decoded features.
