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. How to use: 1. Open the floor plan view containing your seating (chair families). 2. Go to the BIM Hive tab and launch C-Value Analyzer. 3. Enter the eye height and lateral tolerance, in millimetres. 4. Choose a selection mode and click Select Chairs to pick the seats. 5. Set the focal selection (point, line, or element outline) and pick it in the view. 6. Click Analyze to calculate the C-value for every seat. 7. Use Show Coloring to band the seats, Show Focal to check the reference, and Export CSV to save the results.
