editing triangles in TIN surface

pcVS

in 3D Modeling

is there anyway I can prevent triangles being formed between breaklines, or delete them once made?
in the picture below my road edges are defined by the green lines, but the surface has been in some areas I don't want it (marked with an X)
using edit TIN surface, I can't seem to remove these areas

    Hello,

    BricsCAD currently doesn't have an automatic triangle removal option, but you can use the following workaround:

    • draw boundary along the outer points of the TIN SUrface
    • run command "TINEdit"
    • select option "Add bOundaries"
    • select the previously drawn polyline (boundary) and the outer triangles will be eliminated.

    Best Regards,
    Blaž

    BlazProsen having used computer Tins for like 40 years ex Civil software rep. I dont have access to TINS in Bricscad, would appreciate your comments about some possible options.

    Delete long triangles
    Delete triangles using a drag line like ssget "F"
    Flip triangles
