Today’s update addresses some issues with international units for older versions of Illustrator.
Previously, decimal precision was limited to 8 places. Using Adobe’s functions for international units limits that precision to 4. Please let me know if this is a problem for you.
Correctly defining the isometric projection requires a tilt value with 5 decimal places, so other projections no doubt need more than 4 also. For that reason, formatting degrees now looks for a comma decimal separator and supports more decimal places, and bypasses the issue of thousands separator for obvious reasons.
