Relation in Drawing

[manjunathrv]

My requirement is something like below in the drawing:

IF PTC_WM_LIFECYCLE_STATE == "Prototype Released"

PART_NUMBER = PART_NUMBER "X"

ENDIF

Ex: If state = Prototype Released then Part number is 12345678X

Else 12345678

Iam not able to make this work.

Is this possible? Anybody to help me?

Now I tried the below:

IF PTC_WM_LIFECYCLE_STATE == "Prototype Released"

PART_NUMBER = PART_NUMBER + "X"

ENDIF

Now the funny thing is every time the drawing or model regenerates it adds one X at the end of part number.

Now my part number looks like 12345678XXXXXXXXXXXXX

Perhaps try 'if it is prototype released, and the part number does not end in X, then add X'?  As I recall, you use string length and extract to check 'ends in X'

[manjunathrv]

The problem is Iam not able to build a working syntax....

How do I use string length in relations?

Ben's approach will also remove the X if the state is no longer prototype released.  If this is desired, use that.  If you want to flag but not unflag, I had originally been suggesting

if (extract(part_number, string_length(part_number), 1) != "X")

but looking at the dialog to find the precise syntax, I noticed

if (string_ends(part_number, "X"))

which is easier to read.

The part number should have X only for Proto state. for rest of the state its just the part number.

I will try your suggestion too.

Thank You.

Every regen recalculates the relations, so the extra 'X' will get added.

Try this syntax:

IF PTC_WM_LIFECYCLE_STATE == "Prototype Released"

New_part_number = Part_number +'X'

else

new_part_number = Part_number

endif

Thanks Ben. You got it.

I just changed this to :

IF PTC_WM_LIFECYCLE_STATE == "Prototype Released"

part_number = New_part_number +'X'

else

part_number = New_part_number

endif

This works for me.

Thanks for your time.
