IPlane offers a way to extend any plane through all objects in the scene (pseudo infinite plane) for use in any command step that accepts a planar surface as input.

When used nested in a command such as Trim, the plane is temporary- that is, it can be used as input in the command but disappears when the command ends.
IPlanes can be extended from planar surfaces or curves, construction planes, or any of various ways to define the plane as presented at the command line.

Infinite plane as a trimming object.

Shortcut: IP

The InfinitePlane option can be used in the steps that accept a surface as input in these commands:

To create an infinite plane

At any prompt to select a surface or polysurface, type IP or InfinitePlane
At the prompt, select a planar object to use as a temporary infinite plane.
This can be a planar curve, surface, polysurface face, a single polygon mesh, or a clipping plane.
The plane of the object defines the location and direction of the infinite plane.
A reference plane appears in the viewport. The reference plane uses the Tracking lines color.

Options that draw a new infinite plane

Use these options to draw a new infinite plane.

Command-line options
3Point	Three points define the location and the direction of the plane. 3Point steps Pick the first point of plane. Pick the second point of plane. Pick the third point of plane.
Vertical	Two points define the direction of a plane vertical to the active construction plane. Vertical steps Pick the start of vertical plane. Pick the end of vertical plane.
ThroughPoint	A point defines the location of a plane parallel to the current construction plane. ThroughPoint steps Pick a point to define the height of the plane in relation to the current construction plane.

Command-line options

3Point

Three points define the location and the direction of the plane.

3Point steps

Options that use existing construction planes as reference

Use these options to use construction planes to define infinite planes.

Command-line options
NamedCPlane	A named construction plane defines the infinite plane. Custom construction planes must already exist. NamedCPlane steps Type the name of an existing construction plane.

NamedCPlane options
SelectInViewport	The construction plane name and xy axes symbol appear at the named construction plane origin. SelectInViewport steps Hover the mouse over a set of axes until it highlights and click.
SelectFromList	Select from a list of named construction planes.
CPlaneXY	Use the xy directions of the current construction plane to define an infinite plane.
CPlaneYZ	Use the yz directions of the current construction plane to define an infinite plane.
CPlaneZX	Use the zx directions of the current construction plane to define an infinite plane.
WorldXY	Use the xy directions of the world axes to define an infinite plane.
WorldYZ	Use the yz directions of the world axes to define an infinite plane.
WorldZX	Use the zx directions of the world axes to define an infinite plane.
