HI Richard, I am using the 2019 version... and the padlock button isn't in the software. How can I block the model?

I'm working in a large pipeline model, with 6000 nodes aprox, so when a change a restraint or anything, the graphic model redraw the complete model and this takes 5-8 seconds for every change, and I have to change 2 parameters of a 3000 restraints, so you undersad that is a lot of time.

In 2018 version the padlock button was in the "reset and refresh" toolbar, I used to use this button a lot before.

Thanks
