Parameters' filter pattern.

[GiuseppeMicheli]

Is it possible to define parameters' filters using other keywords than "*" in order to achieve a deeper filtering result?
For example, having to distinguish an object named "BLADE_1_2" from another one whose name is "BLADE_A_B" in order to show/hide only the first one, a regex expression such as (BLADE)(_[1-9]){2} would almost do the job.
Is there any possibility to define a filter within CREO to get the same result?
Thanx.

You can do similar things, but it's not going to be pretty, as is often the case when working with Creo relations. Here's an example:

XX = "BLADE_1_2"
AB = "BLADE_A_B"
NUMBERS = "1234567890"
CHECKSTRING = XX

if extract(CHECKSTRING,1,5) == "BLADE" && search(NUMBERS,extract(CHECKSTRING,7,1)) != 0
CHECK = true
else
CHECK = false
endif

This gives CHECK as "Yes", but if you change the CHECKSTRING to AB, it gives you a "No".

It uses the NUMBERS parameter as a storage of certain characters and then checks if a specific character is contained in that string. You can even do something like "search for the first occurrence of a '_' character, then look at the next character and see if it's a number". But it's cumbersome, and the lack of loops makes it really limited.
