how to create a plane parallel to screen?
Planes Parallel to Screen
You can create a reference plane that is parallel to the screen without using the Plane PropertyManager.
Right-click a face in the graphics area and click Create a Plane Parallel to Screen. The software adds an On Plane or On Surface 3D sketch point where you right-clicked and positions a reference plane parallel to the screen at that point.
The sketch point may move if the surface moves. To ensure that the sketch point does not move, set its position relative to other geometry.
In the previous release, you could only create a plane parallel to the screen at a reference vertex.
