As of Inventor 2026.2.1, tolerances for hole dimensions placed via Hole and Thread notes generates inconsistent spacing, at least w.r.t. symmetrical tolerance. Regardless of how the tolerance is defined (with drawing-level tolerance functions or at part level via parameters), the +/- symbol is followed by a space but not preceded by one (first image below). If one tries to workaround by adding a space character after <HDIA> in the formatting window, it's not ignored, but added following the tolerance value (second image, kind of hard to make out).
