I attached a minimal version of the project.
Assuming you have a table of points.
In query [VerticalSection] you only need to change one or two values.
---- Change this to the table where points are
VALUE @pointz TABLE = [your-table-name];
If your points are in Lat/Lon projection use some small value like 0.00001or transform your points
---- Change the section width (in coord sys units)
VALUE @sectionWidth FLOAT64 = 1;
Put your-points and [Section] drawing on the same Map.
Delete all lines in [Section]. Draw 1 line in [Section]
Open drawing [VerticalSection Drawing]. If it is already open then refresh (Ctrl+F5) and Zoom To Fit (Ctrl+click on layer tab).
