Mouse Blade

In my game I am try to make ti so when I press and hold the mouse button I can move it and than when I let it go it slices at the angle which I drew. Essentially if I am looking at the object and press the mouse button and move it at a 45 degree angle and let go of the mouse button it will slice the object at that angle. Ive already made it so my crosshair/Cursor can cut procedural meshes I just cant figure out the “drawing” part of the cut. I’m pretty new to Unreal and don’t really know how to even get started so if anyone has any advice that would be great.
