This document provides instructions for adding shared IFC parameters to a Revit family using Dynamo and Excel files. The graph imports enumerations from an Excel sheet into Dynamo to create shared parameters in the family. It allows setting each parameter as an instance or type parameter and assigns IFC export properties.

2. Add Shared IFC Parameters to
a Revit Family
Created with:
Revit 20.2.20.31
Dynamo Core 2.3.0.5885
Dynamo Revit 2.3.0.8352
Clockwork v.2.3.0
Data-Shapes v.2019.2.42
Orchid v. 230.0.1.7437

3. How the graph works
Start a new Family, this graph does
not work in Revit projects.

4. How the graph works
Set the correct filepaths for the indicated files.

5. How the graph works
The input for that dialogbox are the sheetnames.
(Sheet 1-2 are settings, sheet 3-5 are not used in this graph)

6. How the graph works
This sheet is then split on the line
where ENUMERATIONS is.

7. How the graph works
This sheet is then split on the line
where ENUMERATIONS is.
Additional Properties for some
Enumerations are taken out.

8. How the graph works
Only the enumerations become the input
for the second dialog-box,
NOTDEFINED
Green text is the default enumeration
Choose < Empty > if this is what you want.

9. How the graph works
Column E says wether the Property will become an
instance (1) or a [Type] (0) Parameter.
The third dialog-box gives you a chance to change this
without changing the excel.

10. How the graph works
SharedParameters are created.
Instance parameters and Type
Parameters are different and
originate from the different Shared
Parameter files.
Don’t set instance to type and vice
versa since the GUIDS are
different!
IfcExportAs is set to the chosen
Entity.
IfcExportType is set to the chosen
Enumeration.
Your active Shared Parameterfile
is restored.
