Hi everyone! I think we already talked about this but I can not find the post… I want to connect 2 vertices quickly, ok? With one selected, I want click on another vertex (with Shift + OSKey pressed for example) and automatically join them.
Hi, you can import macro_operators.json file, find Connect 2 Vertices macro and change the hotkey.
It works in all modes. Move the mouse over the first vertex, press and hold down the hotkey, move the mouse over the second vertex and release the hotkey.
