Trimming Triangles

I have imported an irregular shape of Lidar 3d points from an ASCII file and generated an Elevation Grid and a Triangulation. Is there a way I can trim the triangles back and re-generate the grid so that a 3d view will be limited to the extents of the original points boundary ?

    Do you have the point boundary as a polygon/area feature (or could you easily draw one with the Digitizer Tool)? If so, you could simply select that boundary area, then export your elevation grid to some format and use the option on the Export Bounds tab to specify that you want to crop to the selected area. This should crop your grid to the specified boundary.

    Let me know if I can be of further assistance.

    Thanks,
