Text Along Line

[Anonymous]

Hi,

Using the following code trying to place textnote along pipe curve but results are not correct as the textnote doesn't rotates along the line. This I am doing in 3D view. I am creating a ModelLine using the pipe's curve and then creating textnote which should follow the ModelLine.

// get the curve of the element
Curve curve = ((LocationCurve)elem.Location).Curve;
              
// get start and end point of pipe
XYZ PipeEnd = curve.GetEndPoint(1);
XYZ PipeStart = curve.GetEndPoint(0);

 // get vector representing the pipe
double difX = (PipeEnd.X - PipeStart.X);
double difY = (PipeEnd.Y - PipeStart.Y);
XYZ baseVec = new XYZ(difX,difY, 0);

Double textRad = Math.Atan2(baseVec.Y, baseVec.X);

var testOptions = new TextNoteOptions() { HorizontalAlignment = HorizontalTextAlignment.Center, Rotation = textRad, TypeId = (doc.GetElement(texttypeID) as TextNoteType).Id };
var text = TextNote.Create(doc, view.Id, origin,strText, testOptions);

Thanks & Regards

Dear Jeremy,

Already using the code as suggested but the getting wrong results.

Output when not specifying angle in TextNoteOptions

Output When specifying angle:

Thanks & Regards

The sample is presumably using a 2D view.

In a 3D view, the required text orientation will be different for each point of view.

Therefore, it makes no sense to try to add the text in a 3D view.

Consult with an application expert on the right way to address this and determine the best practices, optimal workflow and solution manually through the user interface first, before trying to program anything.
