How to draw text at Line? How to calc direction for text placed on the line?

I did DrawableOverrule instance and override WorldDraw method.
In this method I have checked:


public override bool WorldDraw(Drawable d, WorldDrawwd)
{
  if (d isLine)
  {
      Line line = (Line)d;


Next I want to draw text placed on the line and I did:

 

   wd.Geometry.Text(line.StartPoint, normal, direction

 

Question is - how to calculate required direction for text that text should be placed on the line? Is it easy way to do it?

 

Thanks!

The Line.Delta property returns a vector along the direction of the line.
