I need some help with rotating an object’s axis. In the picture below, I have an object at the center and three directional lines ending at the same end point in space. How do I rotate the cylindrical object’s axis at the center (object with blue line at center) so that the center object’s axis will align with the directional lines? This is similar to demonstrating the travel paths of bullets firing from a particular point in space hitting the objects at the ending locations (fictional as is not real!). I need help with fixing one end of the center cylindrical object and rotate in 3-D in space to align the travel paths. Please notice that the surface of the center cylindrical object must always be perpendicular to the travel axis (I am not able to demonstrated in the attached picture). Thank you in advance for any tips that you can offer.
