Hello guys I have some questions about creating lines.
As shown in the figure, I have an imported object B. When I click to select a face（named selected face）, a plane can be seen. Now I want to create a line between A and the selected face. For this I need three points, and two of the endpoints are: one is the bottom midpoint of the plane, the other is a point on the selected face (the center is offset by a little bit), is there any way to get these two points?
I try to create two lights, and then move the lights to the position I want, but no matter how I adjust the lights, they are always offset, so I want to know if there is any better way to help me get these two points?
Thanks in advance!!
