Can I constrain the reference plan?

Hi,

I'm trying to make a reference plane and the ends of the plane snap to the two intersection points as shown in picture below. I'm trying to lock the plan to the points but seems I can't do this in Revit. Anybody has any ideads how I can make this work? Thanks.

Also, when I try to dimesion the angle of the plane, it says the plane is constrained. Is there a way I can check the constrains of the plane?

As the name implies it is is a plane. This means it extends to ínfinity.

If you are in the family editor you can use a reference line. Reference lines have ends.

Lines can extend to ínfinity, why you can constrain a line? If we can constrain a plane, life will be much easier.

BTW, I find a way to work around it. I made a inclined extrusion first and then snap to the the surface of that extrusion.
