"Control Point #2" -5.64690812e-01 -5.65085273e-01 1.09244112e+00  Distances Will create a *ControlPoints3D.txt file - defines the distances as seen in the measurements tab, as "Control Point #2" "Control Point" 2.33824531e+01 The "scale model with control point" function Just below the "Export data" button it is possible to find the "scale model with control points" function. By defining at least three constraints (1) it is possible to scale the model using the mentioned control points. It is possible to either directly set constraints from text file via the "Import constraints from file" button or manually. Please note how each control point can be set as Control point, Constraint, or both by using the checkboxes on the left of each point. It's always a good idea to include some control points that are not set as constraints . 3DF Zephyr Aerial also shows another option, which is the ability to directly change the reference system (2).
