Via 'get midpoint' from the context menu it is possible
to generate both, start and end points as ,calculated midpoints' between two input points.
Just select the function for the desired point (start or/and end) and define the input points.
Your input will be displayed as a construction line with a midpoint with the definition of the the inputpoint.
Besides that the cursor will guide you during the input process.
The midpoints then are taken as startpoint or endpoint directly without further input.
The construction line , however, does not follow the terrain, so it may disappear under the mesh in some situations.
