Vectors Panel
Use the Vectors panel to create a vector entity.
Location: 1D and Analysis pages
A vector represents a three dimensional direction.
In the modeling window, vectors are displayed as an arrow with the letters VEC and their vector size value at the tail end. By default, vectors are displayed using a representation of 100% of their actual length.
You can create several vectors at a time by selecting nodes and either a magnitude, or by deriving them from a line tangent or surface normal. Single vectors can be created by selecting two nodes or by deriving them from the cross product of two existing vectors.
Create Subpanel
Use the Create subpanel to create vectors.
Using base and magnitude, select one or more nodes at which to place vector entities. Specify the vectors by entering x, y and z components or by using the vector method. For the vector method, you must specify a magnitude and a direction. The direction is determined with a standard plane and vector selector by choosing two or three nodes (N1, N2, and N3), selecting a global axis, or selecting another vector. When using the N1, N2, and N3 option, two nodes define a vector along the selected nodes, while three nodes define a vector that is perpendicular to the plane defined by the selected nodes (using the right hand rule).
A vector can also be created by selecting two nodes using the two node vector creation method. No additional input is required in this case.
The cross product option derives a vector from two existing vector entities. The vector will be perpendicular to these vectors. The length can be entered or taken from either one of the selected vectors.
Option  Action 

vector creation method  Choose a method for
creating vectors.

base node: nodes  Select all of the
nodes where you want a vector to be created.
Note: Available when the vector creation method is set to
base and magnitude.

face angle / individual selection 

edge angle 
Split edges that belong to a given face. When the edge
angle is 180 degrees, edges are the continuous boundaries of faces. For smaller
values, these same boundary edges are split wherever the angle between segments
exceeds the specified value. A segment is the edge of a single element.
Important: Only available when the entity selector is set to nodes and the
selection mode is set to free edges, free edges ext, edges, or edges
ext.

from node / to node 
Create a vector by selecting two nodes.
Note: Available when
the vector creation method is set to two nodes.

base node: node 
Select a node for the vector location. One vector can be
created at a time.
Note: Available when the vector creation method is set to cross
product.

vector A: vector 
Select vector A.
Note: Available when the vector creation
method is set to cross product.

vector B: vector 
Select vector B.
Note: Available when the vector creation
method is set to cross product.

lines/surfaces 
Choose whether to derive vectors from lines or
surfaces.
Note: Available when the vector creation method is set to on
geometry.

nodes 
Select all of the nodes where a vectors needs to be
created.
Note: Available when the vector creation method is set to on
geometry.

vector size % = / uniform size = 
Choose a method for changing the display size of vectors.
This setting does not affect the vector, only the length of its graphical
representation.

label vector  Display labels for each of the vectors in the modeling window. 
autoscale  Display vectors in relation to the model size. When enabled, the vector size fields are grayed out. 
global system / local system 
Choose whether the vector is created either in the global or a local coordinate system. Example: You select three nodes N1, N2
and N3 which define a vector in the global zdirection (normal of the plane defined
by these three nodes). If the switch is set to local, the result will be a vector
pointing in the zdirection of the local system.
Note: Available when the vector creation method is set to base and
magnitude.

vector / components 

magnitude = / vector A / vector B 
Specify the length of a vector.
Note: Available when the vector creation method is set to cross
product.

magnitude = / use parameterization 
If a vector is created on geometry, the length
can be entered directly or the parametric value can be used.
