Branch diameter and branch length measurement
Advance attribute Line Length can be used for branch length measurement. Line length is an integer number and it represents the length of the line. It supports: a general line (two dimensional or three dimensional distance) and a projected line (e.g. length of branches). When a projected line is measured the user can measure line length using one or two points. These points can be on a random place on/under the line. The precision is better if two points are used.
