The ability to create a central point from scratch.
For example, it could work like in AutoCAD. I want to draw a wall from the centre of a room. I select the tool, press ‘Alt’, choose the first corner of the room, press ‘Alt’ again and select the opposite point in the same room. The first point of my wall is now at the centre of the room.
At the moment, we have to draw 2D line. And it works, but it takes a long time.
