Since triangle flips don’t stick, currently the only way I can figure to control the TIN, without adding more triangles and sometimes undesirable results, is to create a linestring then manipulate the properties to “Override the segment length”. - This is too many steps.
It would be helpful if one of the current line commands had the option, or a newly created command, would automatically ignore the system sampling distance and only triangulate to the horiz nodes without having to manipulate the lines properties.
Something along these lines would certainly make it more efficient to control the TIN.
