i have found the line adjustment options under a layer’s advanced properties menu, which allows me to proportionally amplify lines on that drawing. this works great, but it made me realize that this sort of control would be excellent in the network (in my case, i have many many curvy lines.)
maybe could wire a single “line control” node into as many drawing nodes as desired, and have any lines on the connected drawings receive the manipulation commands from the line control node and adjust lines as instructed.
the line control node could have the same controls as the advanced lines section mentioned above.
might be possible to do this with scripting. i don’t yet know how to script for harmony, though.
