For example, in a folder where you store other corporate standard files, create a parameter file
named IFCexportParameters.txt. You only need to create these shared parameters once. You
can reuse them in multiple families.
2 Use the Family Editor to create a new family or to modify an existing family. See
Own Components (Families)
Add the shared parameters to the family
3 In the Design Bar of the Family Editor, click Family Types.
4 In the Family Types dialog, for Name, select a family type.
5 Under Parameters, click Add.
6 In the Parameter Properties dialog, under Parameter Type, click Shared parameter, and click
Select.
7 Navigate to the shared parameters file that defines IFCExportAs and IFCExportType (for example,
IFCexportParameters.txt), and open the file.
8 In the Shared Parameters dialog, under Parameters, select IFCExportAs, and click OK.
9 In the Parameter Properties dialog, under Parameter Data, for Group parameter under, select
IFC Parameters.

Specify values for IFCExportAs and IFCExportType
When you add the shared parameters to one family type, Revit Architecture automatically adds them to all
types in that family. Next, you can specify values for each parameter in each family type.
16 In the Family Types dialog, do the following:
a For Name, select a family type.
b For IFCExportAs, specify the desired IFC class.
c For IFCExportType, specify the desired IFC type.
d Click Apply.
17 Repeat Step 16 for each of the remaining types in this family.
18 When you have defined values for all family types, click OK.
19 Save changes to the family.
20 If you want to load the updated family into a project, open the project. Then return to the
Family Editor, and click Load into Project.
Check parameter values in a project (optional)
Optionally, you can verify the IFC export parameter values assigned to an element in a project.
21 In the project, select an element that belongs to a family to which you added the shared
parameters IFCExportAs and IFCExportType.
