Hi!

Is it possible to trim/slice the TIN surface so that I only keep the area inside the red extracted boundary (extruded surface)? I want to get rid of the TIN surface outside of the boundary.

    use the TINEDIT command with the option Add bOundaries

    : TINEDIT
    Select TIN surface [selection options (?)]:
    [Add Points/Add Point Groups/Add Breaklines/Add bOundaries/Remove Points/Swap Edge/Point Location/Point Elevation/Add Line/Delete Line/Remove Outer Edges/Minimize Flat Areas/Remove Elevations]: ab
    Select entities for breakline: [selection options (?)]:
    Entities in set: 1
    Select entities for breakline: [selection options (?)]:

    an extruded surface cannot be used as a boundary, use a closed polyline instead !

    Thank you so much Sakko, I didn't think you could use a polyline drawn on Z-level 0 as a boundary on a surface higher up, but it worked out excellent!
