When targetting to all the geometry (feature lines) of a certain layer, sometimes you get undesired results such as targetting to the wrong side of the corridor, using elevations from geometry of the other side of the corridor baseline,...
You can prevent targetting to the wrong side by using the option 'Use targets on the same side as the subassembly'. BUT, this option is only available when using horizontal/width targets.
This option should also be available with elevation/profile targets to prevent subassemblies target to e.g. elevations of feature lines in the other side of the corridor baseline. This could prevent the use of 'double layers' (layer_left and layer_right) to work around the lack of this option.
