Extract String at first comma BACK from pos 25? 1

[Hallec]

Hello gentlemen, I have a question about parsing strings so that I can properly format the DWG title in the new formats I'm working on.

We use your typical ASME Y14.100 drawing title scheme: Text, Text, Text, Text, Text
Our DWG titles are limited to 50 characters (legacy software of course) which perhaps simplifies things a bit because we know the absolute limit to the title.
I have a parameter "TITLE" which historically has been used to contain the entire dwg title.
I also have two other parameters DWG_TITLE1 & DWG_TITLE2 to accept the output of my relation.

My thought is to run a relation that checks the TITLE parameter for string_length, and if greater than 25, at the 25th position, go BACK to the previous comma and extract everything from that point to the end of the string.... Put that output into DWG_TITLE1 and the rest into DWG_TITLE2.

Now, I have almost zero prior experience with these relations beyond x+y=z but I've managed a little progress using Google. So far, I've got:

IF string_length(TITLE) > 25

DWGTITLE1 = extract(TITLE,1,search(TITLE, ","))+extract(TITLE,search(TITLE, ","),string_length(TITLE)-search(TITLE, ","))
DWGTITLE2 = extract(TITLE,string_length(DWGTITLE1),search(extract(TITLE,25,string_length(TITLE)),",")-1)


And basically I'm not having any luck... I was hoping for something like:

TITLE = PLATE, L-ARM, CONVEYOR, RECEIVING, PANEL, BODYWELD
DWGTITLE1 = PLATE, L-ARM, CONVEYOR,
DWGTITLE2 = RECEIVING, PANEL, BODYWELD

But what I'm getting is something illogical. Before I spend too much time on this I was hoping some of you relation pro's could make sure I'm headed in the right direction? I'm not sure how to get Creo to start looking for commas AT a certain position or how to go in a particular direction (from pos25 --> pos1). Also, I suppose one other requirement is that it extracts one character AFTER the first comma back from pos 25. And now that I'm typing this, I suppose I'll also need it to delete the first space after that comma.

Boy, this is quite an issue we're left to deal with... It;s astonishing to me that a simple, workable text wrap hasn't yet been incorporated into Creo 4 (M080),

Any help is greatly appreciated!

Lacking loops and arrays, this isn't something that Creo relations can do, and therefore cannot be processed entirely within Creo.

My first take would be to reverse the operation and make title1 and title2 the driving parameters and make title = title1 +", "+title2 within an IF statement =>

title = title1
IF exists(title2)
title = title1 + ", " + title2
ENDIF

If that won't work for you, if allowed, I'd use AutoIT and make a couple of mapkeys to decrease the effort to manipulate the Creo interface. Alternates include using VBA from Excel or Word to run the mapkey using "Sendkeys"

https://docs.microsoft.com/en-us/of...erence/user-interface-help/sendkeys-statement

Final alternate is to create a mapkey that sends the data out using a @SYSTEM statement. For that you'll need to know MS CMD language to create a CMD script to run to handle the text manipulations. Example #SYSTEM use:

Not very elegant since as 3DDave says, Creo does not have looping or array code.
I tested it with both of the Title strings to get different lengths and these seem to work.
I will NOT guarantee it will work with any string thrown at it.
I did stop after extracting the first 4 words, since I figured with 5 letters per word and 2 additional characters ', ' that would hit your 25 limit.
Have fun with it, play with it, it may serve your needs for years.


/*TITLE = 'PLATE, L-ARM, CONVEYOR, RECEIVING, PANEL, BODYWELD'
TITLE = 'BRACKET, CONVEYOR, PANEL, RECEIVING, BODYWELD'

len=string_length(title)
text1=extract(title,1,search(TITLE, ",")-1)
len1=string_length(text1)
tt1=extract(title,len1+3,len-len1-2)
text2=extract(tt1,1,search(tt1, ",")-1)
len2=string_length(text2)
tt2=extract(title,len1+len2+5,len-len1-len2-4)
text3=extract(tt2,1,search(tt2, ",")-1)
len3=string_length(text3)
tt3=extract(title,len1+len2+len3+7,len-len1-len2-len3-6)
text4=extract(tt3,1,search(tt3, ",")-1)
len4=string_length(text4)

if (len1+3+len2+3+len3) >25
maxlen1=len1+3+len2+3+len3
else
maxlen2=len1+3+len2+3+len3+3+len4
endif

If maxlen1 < 25
DWGTITLE1 = extract(title,1,len1+2+len2+2+len3)
DWGTITLE2=extract(title,len1+3+len2+3+len3+2,len-len1-2-len2-2-len3-3)
else
DWGTITLE1 = extract(title,1,len1+2+len2)
DWGTITLE2=extract(title,len1+3+len2+2,len-len1-2-len2-2)
endif

Holy... Hey looslib, that's great!! Thank you for putting that down for me. I may need to tweak it here or there, but after initial testing it looks like that works!

I owe you a beer.

Hey, so I just have one final question... If I wanted to ensure that the comma at the end of the line break was always included (e.g. BRACKET, CONVEYOR, <2ND LINE> PANEL,...) how would I go about doing that? Currently what happens is that the comma at the end of line 1 gets removed. I went through and tried changing some of the values for text1, text2, etc., but now I get the comma and the first two letters of the first word on the second line are being truncated.

This is great and it gives me a really good starting point. Thanks again.

Change these lines:
DWGTITLE1 = extract(title,1,len1+2+len2+2+len3+1)
DWGTITLE1 = extract(title,1,len1+2+len2+1)
That will grab the comma that already exists 1 character beyond the word lengths.

The other method would be to add just the comma:
DWGTITLE1 = extract(title,1,len1+2+len2+2+len3+',')
DWGTITLE1 = extract(title,1,len1+2+len2+',')

I think I figured it out...

I tweaked some of the extract strings and changed the position or length values. It works!

I may need to add a LEN4 as well as a DWGTITLE3 IF/THEN scenario but otherwise this works great!

I need some additional help on this... This works for the most part, but there are a couple of additional conditions that I need to incorporate and if anyone can help, I'd greatly appreciate it.

1) The end of each line, whether it be two or three lines (but not one line - which rarely will happen), needs to end with a comma, which will be a part of the TITLE parameter (so, it doesn't need to be added... It just needs to be not removed).
Light,_Utility,_Garage,
Site 2,_Northeast Installation,
C-Series 3

2) The space after the last comma on lines one and two (because there's never more than three lines) must be removed in order to maintain proper justification. It would also be acceptable (and maybe even preferable) to remove ALL spaces after commas.
Light,_Utility,_Garage,
Site 2,_Northeast Installation,
C-Series 3

OR
Light,Utility,Garage,
Site 2,Northeast Installation,
C-Series 3

I think that's it... Once those two variables are accounted for, this will be ready for testing within the department. Many thanks to all who have helped already.
