About Mapping names of Variables or Parameters
Mapping of names of PTC Mathcad variables or Creo Parametric parameters requires special care. Follow these guidelines when you use PTC Mathcad worksheets with Creo Parametric.
• Creo Parametric disregards case-sensitivity in names of PTC Mathcad variables. The names are always represented in uppercase in Creo Parametric.
• Creo Parametric does not distinguish between PTC Mathcad variables having the same name but with different display attributes such as bold, italics, or bold italics. In Creo Parametric, the name is always represented in plain text.
• Do not tag a PTC Mathcad variable that contains Greek and other non-Latin characters such as pi, sigma, and so on.
• When you map a PTC Mathcad variable name containing a literal subscript character, the name changes such that the subscript character is preceded by an underscore in Creo Parametric. The converse is also true. For example, ax changes to a_x.
• Creo Parametric does not support the mapping of PTC Mathcad variables names with superscripts, special characters, spaces, and vector or matrix elements.
• Creo Parametric supports PTC Mathcad variables names that are alphanumeric, in uppercase or lowercase, and with literal subscript and underscore characters.
• Creo Parametric supports PTC Mathcad units that have superscript characters. For example, in2.
• Creo Parametric does not support the mapping of PTC Mathcad variables names that are longer than 32 characters.
• You can map Creo Parametric parameters or dimensions and PTC Mathcad variables only if they have the same unit type. If you want to map a PTC Mathcad unit that does not exist in Creo Parametric, create a custom unit in Creo Parametric to match the unit of the PTC Mathcad variable.
• Use only lowercase characters when tagging a Math region using the value proe2mc or mc2proe.
• Apply the proe2mc tag only to those Math regions with the definition symbol :, for example, x:=45.78 in , where x is a PTC Mathcad assignment variable and in is the units.
• Do not apply the proe2mc tag to a Math region such as y:=x+25.14,x+y:=45.7 newton ,F(a,b):=123.45 cm , or y=<result>.
• Apply the mc2proe tag only to those Math regions with the evaluation symbol =, for example, y=70.92 in, where y is a PTC Mathcad results variable and in is the units.
If your PTC Mathcad variable does not adhere to the Creo Parametric mapping guidelines, either change the PTC Mathcad variable or reassign such variables to a new variable with the name adhering to the mapping guidelines.
