Adding and Removing Shared Parameters

This program adds or removes shared parameters from a family

Example of Removing shared parameters from a family (run while in the family editor with the family open)

//Delete all parameters that start with something

famMan = doc.FamilyManager;

IList<FamilyParameter> familyPar = famMan.GetParameters();

using (Transaction t = new Transaction(doc))

{

t.Start("Delete parameters");

foreach (FamilyParameter fp in familyPar)

{

if (fp.Definition.Name.StartsWith("Lighting") && !(fp.Definition.Name.Contains("EMEGENCY")))

{

famMan.RemoveParameter (fp);

} //end foreach

t.Commit();

}//end using transaction

2^nd Example of Removing all parameters from a family that can be removed: (run while in the family editor with the family open)

//or delete all parameters that can be deleted--------------------------------------------------------------------

famMan = doc.FamilyManager;

IList<FamilyParameter> familyPar = famMan.GetParameters();

using (Transaction t = new Transaction(doc))

{

t.Start("Delete parameters");

int n = 0;

foreach (FamilyParameter fp in familyPar)

{

try

{

famMan.RemoveParameter (fp);

}

catch

{

n=n+1;

}

}

t.Commit();

TaskDialog.Show("Revit Remove Family Parameters", "Could not remove " + n.ToString () + " parameters.");

} // end using transaction

Example of Adding shared parameters to a family (run while in the family editor with the family open). Adds all the parameters from a group called 01- General. Change “01-General” to the group name in your shared parameter file. Or delete :

if (dG.Name.ToString() == "01 - General")

to add all shared parameters.
