Plane and Vector Selector
The Plane and Vector selector is used in many panels, the Entity Editor or dialogs to define a plane or a vector (direction) to perform a certain function.
For example, the Translate panel requires that you define the direction of translation, while the Reflect panel requires a plane for the creation of the mirror images of the entities selected.

(Switch)
- Select the method for defining the plane or vector.
- x-axis, y-axis, and z-axis
- Define the first, second or third axis respectively of a coordinate system in your model. This coordinate system may be the global coordinate system, or a local system when one can be explicitly specified. Local systems may be rectangular, cylindrical or spherical.
- vector
- Specify a vector entity (created in the Vectors panel). This includes vectors defining coordinate systems, and loads as well.
- N1, N2, N3
- Define a vector (N1,N2), or plane (N1,N2,N3). When defining a plane, the resulting vector is normal to this plane following the right hand rule, and passes through either N1 or the base node (if one is specified).
- screen normal
- Define a vector that is normal to the screen. For planes, as the vector defines the plane normal, the plane is within the screen.
- screen parallel
- Define a vector that is within the screen. For planes, as the vector defines the plane normal, the plane is perpendicular to the screen.
- Node Buttons
- When a node button is active (outlined with a blue border), you can select a node in the modeling window to automatically define it's coordinates. You can also click a node button to manually enter a node's coordinates. Once a node is selected, the next node button will automatically become active.
(Reset)
- Clear your selection (vector, N1,N2,N3 and base).
