To slice a geometry, please start and end outside the edited geometry. To better understand how to use this tool please look at the screens below:

To add next point please simply click in the location where you want to place it.

The segment will change its opacity. Now we can decide if we want to finish or set next point for the Incise operation. To finish it we can use one of following two methods:

We can double click with left mouse button and Incise operation will finish.

2. We can use right mouse button to open a context menu and click Finish button.

Finishing the operation will change the colour of edited geometry.

Now we can decide if we want to Shift or Delete a part of edited geometry. Other use cases describe how to perform both operations.
