Go to “File commands” control panel again. Click on rectangle next to “Action” to show action options menu. Choose “Insert point”. The “Insert scrap” button will change into “Insert point”. Press it to begin inserting points. All this steps could be done by pressing “Ctrl-P”. We are in “point insertion mode” now. Look at the bottom of the window: you'll see a red box showing what we are going to do: insert point.
By default, Xtherion will create points with last type you used. So the fastest way is to create all points of the same types (i.e., stations) then change type (i.e., stalactite) to insert all stalactites, and so on.
