As an example of this:

Here's a hinge mechanism: https://files.catbox.moe/06g9cg.png

Here's the very first sketch in the timeline, I've just clicked on this to edit it, there was no undoing required: https://files.catbox.moe/xzr3un.png

Here it is overlaid on the model, which just requires a single mouse click to toggle: https://files.catbox.moe/339fvg.png

Here it is after I changed a bunch of numbers: https://files.catbox.moe/pvykrx.png

Here's what it looks like when I press the button to show the final model again: https://files.catbox.moe/6bjc0c.png

Just like that the entire model has changed based on the initial sketch. I didn't have to go edit any other features here.

As a bonus here's the assembly being moved by dragging the mouse after those changes, showing that this might not be the most well-designed hinge after those changes: https://files.catbox.moe/eztkja.mp4

Also here's the timeline I mentioned, you can see how I've clicked on a feature and it shows me exactly what it did, this also works when clicking on part of the model: https://files.catbox.moe/f0bb2k.png
