When I use lathe and path, how to add lines at the end of the path
You add points simply by tapping on empty space. However this doesn’t work anymore once you have tapped the green dot, in order to generate the lathe. After you tapped the dot you can only add new points in-between the 2 outside ones.
You can also use “curve” and draw whatever you desire. This probably will give you way more points than you actually need, but you can get rid of points by dragging them into their neighbors.
