    This is my third try, on my second try, I setted the coordinate system at the center of the triangle since I want to have more control, then I put the extrusion family at the same spot(crossing of the plane) to make it relate to the project coordinate system (0,0) point.  The family need  more ” distance parameter” because the profile is locate at the crossing of the plane. However,  when I try to decide the parameter equation, I feel like it might not be the clear and convenient way to do like this way. Therefore, I stick to my original coordinate system location still and modified the paremeter equation.
