Once a Surface has been selected or a glazed element on the model selected, select a Glass Type from the list and use the Fix Surface button.
You will then have 2 options:
a) Apply to the entire building – applies the Glass Type to all instances where this element is in the model
b) Apply to the Selected Surfaces Only – the Glass Type to this Surface(s) only
Once you select an option, click on Apply to proceed.
Then use the Refresh button to update the results on the Dashboard.
