CREO Relations - Repeat Region failing

lockarde — Wed, 11 Sep 2024 18:29:22 GMT

Currently running Creo Parametric 7.

I'm trying to auto-populate a repeat region. In this assembly, there are two cases:

1) XXXXXX-XXXXX-000, where "000" is the component find number. This is a parameter automatically generated at the part level, and can be called via relation asm_mbr_fn

2) The second case is a manually entered find number at the assembly level. This can be called via asm_mbr_cparam_find_number

These cases are mutually exclusive, i.e

Parts that fall under case 2 do not have an automatically generated asm_mbr_fn,

Parts that fall under case 1 do not have a manually entered asm_mbr_cparam_find_number

The components that fall under either case also have a specific naming convention. (see "YYYY", "_XXX" and "_YYYY" below)

Here is the relation I have written - but it is not working correctly, specifically the second IF statement is failing. Those cells in the table are blank. The first IF statement works just fine - it correctly populates the part_name and the FIND_NO.

name_len =string_length(asm_mbr_name) SEARCH_PARAM = search(asm_mbr_name, "_") us_loc = SEARCH_PARAM-1 us_loc_2 = SEARCH_PARAM+1 pn_len = name_len - SEARCH_PARAM IF string_starts(asm_mbr_name, "YYYY") & SEARCH_PARAM>0 part_name = extract(asm_mbr_name,us_loc_2,pn_len) FIND_NO = asm_mbr_cparam_find_number else part_name = asm_mbr_name FIND_NO = asm_mbr_fn endif IF string_ends(asm_mbr_name, "_XXX") | string_ends(asm_mbr_name,"_YYYY") part_name = extract(asm_mbr_name,1,us_loc) FIND_NO = asm_mbr_cparam_find_number endif

It's also worth noting that before I included the FIND_NO lines, the part_name populated correctly for all components. Now only those components that fall under the first IF statement are populating.

I'm scratching my head here - I can't figure out why the addition of the FIND_NO messes everything up. Any help is greatly appreciated!

Can you upload an example drawing, assembly and part files (zipped) that have the proper parameters for testing?

You are in the wrong forum.

PTC has two CAD systems: Creo+ and Creo Parametric and Creo Elements Direct.

Which makes it confusing.

More, for Creo Elements Direct:

- The 3D software name is Modeling, and

- The 2D software name is Drafting.

For Creo+ and Creo Parametric, use only this tab:

You should move your post to this community to have a better chance to get an answer.

Thanks for the response @BenLoosli! After fiddling with it the rest of the afternoon, I was able to get it working. Basically I had to split everything up into separate IF statements. Once I removed the "else" and made that condition it's own IF, everything worked. Which is weird... but hey, it works😂.
