Making big jungle gyms for things like primates is already a big undertaking, but having ropes and vines the way they are just makes the process even more finicky. Here, I propose my own solution.
I made this drawing in MS paint so bear with me
Basically, when you select the option to make a rope/vine, you click on the first place you want to attach it.
Then, you can move your mouse to another hard surface and once you click, the rope/vine attaches to it, making a chain
This will make placing these items and making climbing areas much easier and more fun
