@pentool I understand that you need a tangent mode for the Line tool,
or maybe a separate Tangent tool.
I did say it's not exactly what you want but I posted this because it could
come handy.
Andβ¦ here's another method that could be useful β not exactly what you need butβ¦
add a node to the shape anywhere you want (the green point in your drawing);
draw a line with the Line tool;
enable 'Snap to Shape' and 'Snap to Points' in the Snapping panel;
pick the line with the Collider tool (fourth tool in the toolbar) and snap it along the shape, orβ¦
snap it to the node you just added (to this one it will snap perpendicularly, but
you can rotate it 90Β°)
Again this is not drawing a tangent from the red dot to the green dot, but it's good to know.
