• Creo+ disregards case-sensitivity in names of PTC Mathcad variables. The names are always represented in uppercase in Creo+.

• Creo+ 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+, 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+. The converse is also true. For example, ax changes to a_x.

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

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

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

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

• You can map Creo+ 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+, create a custom unit in Creo+ 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.
