Vertical planes from endpoints
You can use this function to create a vertical plane by selecting two points on the plane in Graphics.
Usually, you would use this function to create an arbitrary vertical plane using location and approximate orientation, instead of a set of coordinates. You can also use this function to create a vertical plane that is near a pair of desired coordinates, and then use VERTICAL PLANES PROPERTIES to change the coordinates of the points to the specific values that define the plane you want to create.
To run this function: Choose Planes > Vertical > From endpoints, or...
Usually, you would use this function while in Plan view. You can also use this function in an inclined view. If you are in an inclined view, and snap mode is set to Plane, the plane is defined as the intersection of the two locations selected, and the bottom of the bounding box in the 3D work area.
Output
A dynamic pane is created, based on the coordinates of the points you selected.
