Hopefully last thing for a while.
I loaded everything, then double clicked on the Course 1 in the Projects window, then hit Human Height, then Cliked on Course Forge On, then pushed the Spline Tool, then chose the Point by Point button, started clicking, say a green shape.
Then as I complete the shape and double clik to connect the last point, it all disappears.
Also if I try to freehand a shape, when I'm done and let off the mouse, it disappears.
If someone could help as to why when I double clik, my shape disappears, I can get going.
I swear I could make anything harder than it is.
