How to extract pieces of strings to assign to a parameter

I need help extracting a string from a system parameter to assign it to a user defined parameter.

Any help would be greatly appreciated.  Please see attached where I explain better what I'm trying

to accomplish.

Update: been trying and it doesn't like system parameters such as model_name.  I can use any other user defined

parameter and it works fine.

Re: How to extract pieces of strings to assign to a parameter

In the case where the filename length is not fixed, you will have to use the if/else/endif solution to test the last character until you find a underscore or period.

Here is an extensive use-case...  see the 1st comment below the document

Re: How to extract pieces of strings to assign to a parameter

If I understand what you are asking, you are also having trouble making the model_name parameter into relations.

This is the trick to make the current model name a relation.  This can be manipulated to extract the substring.

Excellent!  Thanks for your help TomD.inPDX, Got me going in the right direction.

Here's the relation that worked for now:

part_number=(rel_model_name)

part_number=extract(part_number,1,9)

RESULTS IN:

part_number = AA-00-910 (this is good)

But what happens when the part number has more than nine characters?

For example, now I have an assembly where the model_name = AA-00-1234_route.asm

If I use the above expression:

part_number=(rel_model_name)

part_number=extract(part_number,1,9)

would yield:

part_number = AA-00-123 (truncating the part number, it will leave out the number "4" resulting in an incorrect part_number.

Re: How to extract pieces of strings to assign to a parameter

If you want to clip at an underscore, you could use something like this:

part_number = extract(rel_model_name,1,search(extract(rel_model_name,1,string_length(rel_model_name)),"_")-1)

For your example above, AA-00-1234_route.asm will become AA-00-1234

Thanks Christopher.  I'll try that too.
