model_name + "custom text" in a drawing parameter relation

[rburk]

is there any way to add custom "text" to end of drawing parameter relation below?

we'd like to truncate the "model name last 3 characters" then add text "DOC1"

for our drawing title blocks

DOC_NO=extract(rel_model_name(),1,string_length(rel_model_name())-3)"DOC1"

thanks

Drawing programs have a greatly reduced subset of valid commands.  You should be able to display this on the drawing by using a single cell repeat region as long as you don't actually need a drawing parameter populated with this value.  What version of Creo Parametric are you running?

[TomU]

Example with Creo Parametric 8.0

You had it close.

DOC_NO=extract(rel_model_name(),1,(string_length(rel_model_name())-3))+'DOC1'

Test the extract portion to be sure it gives you what you want.

[TomU]

That will work as long as they want to add the relation to the model, but it won't work in a drawing unless it's added to a repeat region.

thank Benloosi,

we are using Creo6

this works

DOC_NO=extract(rel_model_name(),1,(string_length(rel_model_name())-3))+'DOC1'

is it possible to search rel_model_name for "001" - not all model names have "001"

something like this:

if rel_model_name has "001"

DOC_NO=extract(rel_model_name(),1,(string_length(rel_model_name())-3))+'DOC1'

else

DOC_NO=extract(rel_model_name(),1,(string_length(rel_model_name())-3))+'CDOC1'

[BenLoosli]

I did it in steps, but could be combined into a single line.

Relations do have a limit of 80 characters.

The first line finds the start position of the required search string.

rtn=search(rel_model_name,'001')
if rtn <> 0
DOC_NO=extract(rel_model_name(),1,(string_length(rel_model_name())-3))+'CDOC1'
endif

... for a single line.  You can continue a single relations statement on as many lines as you want, you just have to use the continuation character ( \ ) so each line doesn't exceed 80 characters.

[rburk]

can this be written for the drawing program ?

RTN=search(rel_model_name,'001')
IF RTN <> 0
DOC_NO:D=extract(rel_model_name(),1,(string_length(rel_model_name())-3))+"DOC1"
ELSE
DOC_NO:D=rel_model_name()+"CDOC1"
ENDIF

No, drawing programs only allow a few specific commands:

Do you have 1 drawing per model? You might be able to add the relation in the model itself, then reference that parameter in the drawing. This might be a little more flexible to use than dealing with repeat regions.
