Place Text ByFunction

Question

Hi All,

I am a bit stuck with my arrays trying to place some text on a random paving we are looking to document.

I have generated a quick test file with just 10 rectangles representing pavers (just 3 different sizes). Using a simple range box created some GC information so i can label each one.

It is getting close but my text by function is not working the way i was hoping. I am sure I have the function looping itself as it places all the text on each point :)

just wondering if anyone had some tips on the function below. Also attached the DGN file.

Thanks

Wayne

function (BSplineSurface Paver, TextStyle Style, Point CentrePoint)
{
for (int i = 0; i < Paver.Count; ++i)
{

if(Paver[i].Area > 240000 && Paver[i].Area < 260000 )
{
Text textarray = new Text(this);
string label = "A";
Point pnt = CentrePoint;
Text text = new Text(textarray).ByPointOrPlaneOrCoordinateSystem(CentrePoint,label,Style);
}
if(Paver[i].Area > 370000 && Paver[i].Area < 380000 )
{
Text textarray = new Text(this);
string label = "B";
Point pnt = CentrePoint;
Text text = new Text(textarray).ByPointOrPlaneOrCoordinateSystem(CentrePoint,label,Style);
}
if(Paver[i].Area > 490000 && Paver[i].Area < 510000 )
{
Text textarray = new Text(this);
string label = "C";
Point pnt = CentrePoint;
Text text = new Text(textarray).ByPointOrPlaneOrCoordinateSystem(CentrePoint,label,Style);
}
}

}

Hi Wayne, Question: do you want a sublist of labels for each type of paver? In any case, the lines Text textarray = new Text(this); would need to be pulled out of the loop. However, if you are OK with a flat list of text for all labels, you can generate the labels directly as Text text = new Text(this).ByPointOrPlaneOrCoordinateSystem(CentrePoint,label,Style); Otherwise, try this: function (BSplineSurface Paver, TextStyle Style, Point CentrePoint) { Text textarrayA = new Text(this); Text textarrayB = new Text(this); Text textarrayC = new Text(this); for (int i = 0; i < Paver.Count; ++i) { if(Paver[i].Area > 240000 && Paver[i].Area < 260000 ) { string label = "A"; Point pnt = CentrePoint; Text text = new Text(textarrayA).ByPointOrPlaneOrCoordinateSystem(CentrePoint,label,Style); } if(Paver[i].Area > 370000 && Paver[i].Area < 380000 ) { string label = "B"; Point pnt = CentrePoint; Text text = new Text(textarrayB).ByPointOrPlaneOrCoordinateSystem(CentrePoint,label,Style); } if(Paver[i].Area > 490000 && Paver[i].Area < 510000 ) { string label = "C"; Point pnt = CentrePoint; Text text = new Text(textarrayC).ByPointOrPlaneOrCoordinateSystem(CentrePoint,label,Style); } } }
