• Creo Parametric does not distinguish between PTC Mathcad Prime 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 assign a PTC Mathcad Prime variable that contains Greek and other non-Latin characters such as pi, sigma, and so on.

• When you map a PTC Mathcad Prime variable name containing a literal subscript character, the name changes such that the subscript character is included in the name in Creo Parametric. For example, ax changes to ax.

• Creo Parametric does not support the mapping of PTC Mathcad Prime variables names with superscripts. However, special characters, spaces, and vector or matrix elements are allowed.

• Creo Parametric supports PTC Mathcad Prime variables names that are alphanumeric, in uppercase or lowercase, and with underscore characters.

• Creo Parametric supports PTC Mathcad Prime units that have superscript characters. For example, in2.

• Creo Parametric does not support the mapping of PTC Mathcad Prime variables names that are longer than 32 characters.

• Assign as input only those Math regions that have the definition symbol :, for example, x:=45.78 in , where x is a PTC Mathcad Prime assignment variable and in is the units.

• Do not assign as input a Math region such as y:=x+25.14,x+y:=45.7 newton ,F(a,b):=123.45 cm , or y=<result>.

• Assign as output only those Math regions that have the evaluation symbol =, for example, y=70.92 in, where y is a PTC Mathcad Prime results variable and in is the units.
