Generate From

You use the Generate From area to specify where the curves are generated.

There are five options you can select:

• Boundaries to create curves around the triangle boundary. Click here to see an example.
  
  
• Horizon Line to create a curve where triangles are at an specified angle to the current view. Click here to see an example.
  
  
• Discontinuities to create curves on triangle discontinuities. You specify what constitutes a discontinuity in the Discontinuity Angle box below. Click here to see an example.
  
  
• Scanlines to create curves through the selected scanlines. Click here to see an example.
  
  
• Triangle Model Cross Section to create a curve through a cross section you set using the Define Section Plane button below.
