"Revit" Classification

"Revit" Classification

The "HEIGHT " and "WIDTH " or "DIAMETER " feature is used to create the height and width or diameter of the opening to be created.

Set the value for feature RVT_FAMILY_CATEGORY to Windows so that the object is recognized or classified as a window in Revit. If it is an assembly, assign the template to the file *_asmtab.prj and classify it.

[Important]Important

The roof window is aligned with the roof's lower reference plane, meaning the inner side. Should the roof window be aligned with the outer side, have a protrusion or any offset from the roof's lower reference plane, this has to be considered during the modeling. Where appropriate set the connection point (CP) to a separate level, which then can be controlled by a variable.

The roof's thickness can not be queried, so that the planner has to consider this when selecting the roof window (in PARTdataManager table).
