You select geometry and apply constraints to the geometry to define reference planes.
To display this PropertyManager:
Click Plane (Reference Geometry toolbar).
Message
Follow the messages to create a plane and see the plane status. The Message box color, plane color, and PropertyManager messages help guide your selections. The plane status must be Fully defined to create the plane.
First Reference 

Select the first reference to define the plane. Based on your selection, other constraint types appear. 
Coincident 

Creates a plane that passes through the selected reference. 
Parallel 

Creates a plane parallel to the selected plane. For example, select a face for one reference and a point for another reference. The software creates a plane that is parallel to the face and coincident to the point. 
Perpendicular 

Creates a plane perpendicular to the selected reference. For example, select an edge or curve for one reference and a point or vertex for another reference. The plane is created perpendicular to the curve passing through the point. Set origin on curve places the origin of the plane on the curve. When cleared, the origin is placed on the vertex or point. 
Project 

Projects a singular entity such as a point, vertex, origin, or coordinate system onto a nonplanar surface. 
Parallel to screen 

Creates a plane at the selected vertex that is parallel to the current view orientation. 
Tangent 

Creates a plane tangent to cylindrical, conical, noncylindrical, and nonplanar faces. 
At angle 

Creates a plane through an edge, axis, or sketch line at an angle to a cylindrical face or plane. You can specify the Number of planes to create . 
Offset distance 

Creates a plane parallel to a plane or face, offset by a specified distance. You can specify the Number of planes to create . 
Flip Normal 

Flips the normal vector of the plane. 
Mid Plane 

Creates a mid plane between planar faces, reference planes, and 3D sketch planes. Select Mid Plane for both references. 
Second Reference and Third Reference
These sections contain the same options as First Reference, depending on your selections and model geometry. Set these references as needed to create the desired plane.
