Designating Input Regions
Input regions are math regions that contain definitions.
Once you designate a region as an input region, then you cannot edit its content. If you want to modify the definition or if the definition has an error, then you must remove the input designation before you can make the change or fix the error.
Designate a region as an input region to get the following result:
Identifier
Input Value from Creo Parametric

Designate a table as an input region to get the following result:
Identifier

Regions That You Can Designate as Input Regions
Only math regions that meet the following requirements are available for designation as input regions:
regions that contain regular or global definition operators or spec tables
regions that contain identifiers that have valid names
regions that contain valid identifier expressions of scalars, matrices, or strings
For math regions:
the LHS should be simply structured using variables, vectors, or matrices that contain no nested matrices
if the LHS is a matrix of identifiers, then the structure of the definition must be a literal unit-less matrix of identical size whose elements can be any valid expression
For spec tables:
only single identifiers are allowed
matrices of identifiers are not allowed
upon designation, extra columns of the spec table are removed
Examples of regions that you can designate as input:
Regions That You Cannot Designate as Input Regions
You cannot designate the following types of math regions as input regions:
math regions that are embedded in text regions
regions that contain identifiers that have invalid names, such as those containing empty placeholder, no indices
Examples of regions that you cannot designate as input:
To check if you can designate a region as an input region, click or select the region and then on the Input/Output tab, in the Integration group, an enabled Assign Inputs button indicates that you can designate the region. A disabled button indicates that you cannot. Ensure that the region has no errors or that the definition does not violate one of the above rules.
