Hi.

I'm working on a simple add-in that creates a bunch of text styles in a project or family in Revit 2013.

I'm able to only duplicate and add 1 text type and modify it's text parameters.  I'm trying to figure out how to loop it based on an array count.

I want to count & loop depending the the array count for "txtHgt".

But I cannot add a variable counter to "noteType" which is a TextNoteType and this is causing the issue.

                // Action Code Starts Here
                Document doc = commandData.Application.ActiveUIDocument.Document;

                /// Retrieve access to all TextNote Elements
                FilteredElementCollector collectorUsed

                  = new FilteredElementCollector(doc);

                ICollection<ElementId> textNotes
                  = collectorUsed.OfClass(typeof(TextNote))
                    .ToElementIds();

                foreach (ElementId textNoteid in textNotes)
                {
                    TextNote textNote = doc.GetElement(
                      textNoteid) as TextNote;
                  
                    Transaction trans = new Transaction(doc);
                    trans.Start("ChangeParam");

                    //Setting the Variables
                    string txtOPR = "_";
                    string[] txtHgt = { "2.38mm (3/32in)", "1.98mm (5/64in)" };
                    string[] txtbkgd = { "Op", "Tr" };
                    //string txtType = (txtHgt[1] + txtOPR + txtbkgd[1]);
                    //int txtCount = txtHgt.Count;
                    int txtCount = 1;

                    for (int i = 0; i < txtCount; i++)
                       // for (int i = 0; i < list.Count; i++)
                    {
                        //string txtvar = list[i] as string;
                        //Element num = textNote.TextNoteType.Duplicate(txtvar);
                        //TextNoteType noteType4 = num as TextNoteType;

                        string txtType = (txtHgt[i] + txtOPR + txtbkgd[1]);


                        // Create a duplicate
                        Element ele = textNote.TextNoteType.Duplicate(txtType);
                        TextNoteType noteType = ele as TextNoteType;

                        // Change font parameter
                        if (null != noteType)
                        {
                            // Text Colour (only able to modify RGB Red)
                            byte valRed = 0; //Set colour to black
                            //noteType.get_Parameter("Color").Set(4);
                            noteType.get_Parameter("Color").Set(valRed);
                            // Text Line Weight 1-16
                            noteType.get_Parameter("Line Weight").Set(2);
                        }
                    }
                    trans.Commit();
                }
                // Return Success

Any Suggestions?

Hi

I think the problem is with the count in the loop. You should change the code to -

...

//Setting the Variablesstring txtOPR = "_";

string[] txtHgt = { "2.38mm (3/32in)", "1.98mm (5/64in)"};

string[] txtbkgd = { "Op", "Tr"};

//string txtType = (txtHgt[1] + txtOPR + txtbkgd[1]);//int txtCount = txtHgt.Count;inttxtCount = 2;

for (inti = 0; i < txtCount; i++)

// for (int i = 0; i < list.Count; i++)

{

//string txtvar = list[i] as string;//Element num = textNote.TextNoteType.Duplicate(txtvar);//TextNoteType noteType4 = num as TextNoteType;stringtxtType = (txtHgt[i] + txtOPR + txtbkgd[i]);

　

// Create a duplicateElementele = textNote.TextNoteType.Duplicate(txtType);

TextNoteType noteType = ele asTextNoteType;

// Change font parameterif (null!= noteType)

{

// Text Colour (only able to modify RGB Red)byte valRed = 0; //Set colour to black//noteType.get_Parameter("Color").Set(4);

noteType.get_Parameter(

"Color").Set(valRed);

// Text Line Weight 1-16

noteType.get_Parameter(

"Line Weight").Set(2);

}

}

trans.Commit();

...''

After the above changes, I can see both the textnote types created:

Hope this helps.

cheers

The loop is now working.

I'm trying to adjust the loop count based on the number of possible text sizes.

I'm using the following:

                    //Setting the Variables
                    string txtOPR = "_";
                    string[] txtHgt = { "1.58mm (1/16in)", "1.98mm (5/64in)", "2.38mm (3/32in)", "3.17mm (1/8in)", "4.76mm (3/16in)", "6.35mm (1/4in)", "12.7mm (1/2in)" };
                    string[] txtbkgd = { "Op", "Tr" };
                    
                    int txtCount = txtHgt.Length * txtbkgd.Length;

 Which works fine.

The next part is changeing the txtType "string value based on the specific location of the count.

I want to be ablt to change the entered Text Style Type Name after I have completed all possible values for txtHgt & txtbkgd[0].  After I enter those, I want to enter txtHgt & txtBkgd[1].

I'm using the following statement.

                    for (int i = 0; i < txtCount; i++)
                    {
                        if (i <= txtHgt.Length)
                        {
                            string txtType = (txtHgt[i] + txtOPR + txtbkgd[0]);
                        }
                        else
                        {
                            string txtType = (txtHgt[i] + txtOPR + txtbkgd[1]);
                        }

The name 'txtType' does not exist in the current context Error:

Which is saying it's outside the current scope or not defined.

What am I missing?

I have completed the project.

Not 100% clean, but it works.

I had to add some if statements to check for values and increase array values as needed.
