Rotated Plane not rotating around axis

[[Ti...]]

To create a rotated plane there are 3 inputs.

1) Rotation point

2) Normal direction

3) Rotation axis

 

My opinion is if you use the end point of a cylinder for the 'rotation point', then use the same cylinder for the rotation axis. then the entire plane must touch the cylinder axis. Basically both end points of the cylinder should be on the plane b/c the plane is rotating around the axis.

 

I am seeing the plane separate from the axis as seen below. The degree to which this happens didn't bother me until now, so I need to address it. Can someone explain what is going on?

 

Here is my setup.....

 

Here is the separation of the rotated plane and other end of the cylinder:

So I confirmed with a really extreme example that the 'rotated plane' feature does not secure the plane around the entire axis at all. I guess I mis-understood this feature, the way this feature works, I cannot see a need for this feature ever in our workflow. Maybe someone can explain to me why you would want to use this feature.

 

Instead what I am doing is using 'perpendicular plane'. The two points used are the two end points of the cylinder I want the plane to rotate around and stay attached to, then the plane I want the rotated plane to be normal to I click as the last input.....the problem is this plane is perpendicular, so I just have to repeat the same steps above and use the perpendicular plane just created as the input plane.

The 'normal direction' defines the orientation of the plane to be rotated. The cylinder serves solely as the rotation axis. Selecting an endpoint simply repositions the plane to that point, and the plane is then rotated about the cylinder’s axis. This does not constrain the plane to lie on the axis.
If the requirement is for the plane to pass through both ends of the cylinder, the ‘Perpendicular Plane’ feature using the two cylinder endpoints as input is the appropriate approach.
