Temporary cutting plane

It would be good if a cutting plane could be inserted to better remove points within an object. Otherwise, you can’t get there. Like in Fusion360


In this post (From 4 to 5: We're Committed to Improving Our Software) it was mentioned that it has already been implemented. Unfortunately, that’s not quite the case, I really meant that you can cut off a part to then be able to remove points from the inside and edit the edges better. Can this be added to the to-do list again?
