A critical discrepancy in calculation formulas treated string values of "0" identically to an empty string entry. Update 4 implements strict string logic differentiation, correcting automated data evaluation and project validation checks. 3. Corrected Manufacturing Excel Label Outputs

Users can create master macros that contain up to 26 graphical variants.

Before generating a bills of materials, execute a system-wide check via Project data > Messages > Check project . Configure the check scheme to flags short circuits, missing target connections, duplicate device tags (DT), and unassigned terminal designations.
