Macro Manager does not like code

[drodrigues]

I have included a partial piece of my code that basically just draws a line on a plot sheet. It passes when i do the F5 (debugger) but when i get out of the API and try to run it in Macro Manager the Run button is deactivated. This is a test run for another macro that i am trying to put together. I am on 2011 and using windows xp x64. I'm guessing Macro Manager does not like something in the code but i cannot tell what it is??

using XYZ = Autodesk.Revit.Geometry.XYZ;
using LINE = Autodesk.Revit.Geometry.Line;

UIAPPLICATION app = m_doc.Application;

//declare variables
double x1 = (5.0);
double y1 = (5.0);
double z =  (0.0);
double x2 = (7.0);
double y2 = (5.0);
                       
//create object
XYZ point1 = app.Application.Create.NewXYZ(x1, y1, z);   //takes doubles
XYZ point2 = app.Application.Create.NewXYZ(x2, y2, z);

//Create Line
LINE line = app.Application.Create.NewLineBound(point1, point2);

It looks like there's a couple of things happening here from what I can tell.
First off, the Revit.Geometry namespace is no longer used in Revit 2011. You should only need to reference:

using Autodesk.Revit.DB;
using Autodesk.Revit.UI;

Then in the actual code, here's what I used in my VSTA macro:

      public void DrawLine()
        {
            Document doc = this.Document;
            UIApplication app = this.Application;

            //Create the Points
            double x1 = 5.0;
            double y1 = 5.0;
            double z = 0.0;
            double x2 = 117.0;
            double y2 = 115.0;
            XYZ point1 = app.Application.Create.NewXYZ(x1, y1, z);
            XYZ point2 = app.Application.Create.NewXYZ(x2, y2, z);

            //Create line
            Line line = app.Application.Create.NewLineBound(point1, point2);
            DetailCurve detailCurve = doc.Create.NewDetailCurve(doc.ActiveView, line);

            TaskDialog.Show("Done", "Line Created");
        }

What you can do is create a new module in VSTA macro manager, then click CreateMacro and call it DrawLine, then just insert the code from above. What this should do, is draw a long line on the active sheet/view (I edited your distances to make it a bit more noticeable, feel free to change it back). The main thing that differs from your code is that I've added the following line:

DetailCurve detailCurve = doc.Create.NewDetailCurve(doc.ActiveView, line);

It's a little confusing, you have to create a Line, which doesn't actually display anything - it's simply a way of representing some Geometry. Then, we tell Revit we want to create a detail line that matches this geometry by creating a 'DetailCurve'.
