Re: Family Symbol Insert Error

smmoes,

As Aaron stated, it needs to be in the scope of a transaction.

catch (Exception ex)
{
    message = ex.ToString();
    transaction.RollBack();
}

Please note that the family you uploaded only has a type named "Standard" rather than "Rectangular Offset Radius Drop-Cheek"

 

Also: if you want to use a *symbol*, don't forget to make sure it is activated by calling: symbol.Activate();

 

Of course you can use Document.LoadFamily to load the entire family into the document, while LoadFamilySymbol only loads the one you required.

var file = @"D:\---\family symbol insert error\Rectangular Offset Radius Drop-Cheek.rfa";
Family family;
var loaded = doc.LoadFamily(file, out family);
if (loaded)
{
    TaskDialog.Show("Info", family.Name);
}

Aaron,

I have my Symbol creation within the scope of a transaction, unfortunately, still no luck.  Also, I don't think I can use Family, as opposed to Family Symbol because I'm using this to create a Family Instance,  Here is what I have, in it's entirety, right now.  Like I said, this works for numerous other families, it's just sometimes when I modify/save a family and I return to using it in this fashion it just starts failing by telling me it can't load the Symbol. It's odd.

using (Transaction trans = new Transaction(doc, "Family Insert"))
{
   trans.Start();

   FamilySymbol famSym = null;
   FamilyInstance famInstance = null;

   //Location of Family on machine
   string fileLoc = @"C:\Revit Families\Rectangular Offset Radius Drop-Cheek.rfa";

   //Family Name
   string famName = "Rectangular Offset Radius Drop-Cheek";

   //Load Family Symbol
   doc.LoadFamilySymbol(fileLoc, famName, out famSym);

   // Check FamSym integrity.
   if ((!famSym.IsActive) && (famSym != null)) // <-- This is where it fails, we have 'null' for famSym from previous method.
   { famSym.Activate(); doc.Regenerate(); }

   famInstance = doc.Create.NewFamilyInstance(new XYZ(0,0,0), famSym, AutoDesk.Revit.DB.Structure.StructuralType.NonStructural);

   trans.Commit();
}
