Tin Surface delete short lines or Delete small area triangle

[NoelRico]

Hi Everyone,

Is there a way to delete lines in tin surface with length less than 3' or triangles  with area less than 0.5 sf. programmatically? or delete lines or triangle inside close polyline. 

I just want to delete the curb/gutter tin lines and doing it manually using delete line by fence or inside polygon.

I want only to extract tin lines of roadway.

Thanks for any idea and suggestions.

Can you have a picture that shows what you want? Maybe you want to delete the closed polyline after extracting it from the surface

Hi', Thanks for the reply. In Civil 3D Build definition there is Use maximum triangle length but no minimum length. suppose to be I want the minimum length to not include small tin triangles such as the curb and gutter.

in c# there is TinSurfaceMeber called DeleteLine but no sample how to use.

I found this C# code online but only deleting breakline. 

// Get the TIN Surface
TinSurface tinSurface = surfaceId.GetObject(OpenMode.ForWrite) as TinSurface;

// Lets try to Remove Breakline using RemoveAt(int)
tinSurface.BreaklinesDefinition.RemoveAt(0);

// rebuild the surface
tinSurface.Rebuild();

my main purpose is if by using code is to loop to all tin lines then get its length then if less than 3' delete it.

Thanks again
