Summary0003175: inability to link datum line to vertex in correct normal orientation

If I could make a Z axis datum line coincident with a sketch point easily, that would be a good way to locate a cylinder shape...

There are supposed to be two ways to achieve that, but I couldn't make any of them work.
1. Select XY plane + vertex, use Normal mode
->Normal mode is not listed, and doesn't work even if I enforce it.

2. Select the vertex and Z axis, use Tangent mode
-> if vertex is selected first, it was supposed that the line passes through the vertex, but it remains coincident with Z axis.
So... sorry, I don't see a straightforward way of attaching the datum line. I need to dive into code.

Please create a tracker ticket, and post it here, I will assign it to myself.
Steps To ReproduceIn a doc like set tip to the additive pipe, hide the additive pipe and the two datum planes, then select a point of the sketch/vertex that now is all that is left to select. Press datum line button, and get failed attach.

Try with tip set to the body container. Now see Map Mode choices, choose normal. Unhide bottom datum plane and see that it is selected also. Press datum line button and says attached with mode object's X. No line visible yet. Hide bottom datum plane and see a line in the X axis coincident with the bottom datum plane.

this result is not a line normal to a plane, it is parallel instead --> mistake, bug.
