i have two problems over here. QGIS
1- I need to create a perpendicular line to connect multiple points to multiple lines but these lines have to follow a sequence of column.
2- And these perpendicular lines can't be created of differents "id's".
In the image above, you can see the result (In red) that i want. The (Red Line) has to start on the point and connect to the "line.shp" (following column "MDE" from lowest to highest) creating a perpendicular line.
