Multiple Glass Types With The Same Name

If there are multiple entries in Revit’s internal list with the same name, Revit will use the entry which is last in the sequence.  An entry which has the same name in the Glass Database and is chosen for selection, may have a set of properties which do not match an entry in Revit.  This may occur if you create glass types with the same name in Glass Analytics which have different properties.

This may occur where there are several entries in Revit for Glazing Types which have the same name eg. Glass 1.  Once this is applied to a glazing element and is added to Revit, the list may have one entry with one set of properties, a second entry with the same name but with different set of properties.

Revit invariably uses the last entry in the list.  An entry chosen in the Glass Database which appears to have the same name, therefore may not map to the correct Revit entry as expected since there are multiple versions.

Users are therefore advised to create custom glass types with different names and to check the thermal properties in Edit Type to confirm that the entry has mapped correctly and that these are the properties that they intend to assign.
