C-Value

C-Value Analyzer measures viewing quality for stadium and arena seating by analyzing the actual chair families placed in your Revit model. Set the eye height and lateral tolerance, select the seats, and pick a focal reference - a point, a line, or an element outline such as the pitch edge - then run the analysis to get the C-value for every single seat. Results appear in a per-seat table (seat ID, X/Y/Z position, and the calculated C-value) that you can export to CSV for reporting. Color the seats by C-value band right in the view - red below 60, orange 60-90, light green 90-120, dark green above 120 - so you can instantly see which seats meet your sightline target and which fall short.
