Creo relations - 'OR' function

  • January 24, 2014

Hello there.

Is there an 'OR' function or something similar in creo relations (i'm using creo elements/pro)

I have the following string of code, which is what i would like it to look like

IF C_GEARBOX_CD_DIM == 125 OR 150

XD_GEARBOX = 215

ENDIF

this links the user inputted 'CD' and drives the 'XD'

However, there are many figures for 'CD' that would all provide the same 'XD'

I am trying to get around having to write an if statement for each and every 'CD' (there are 72!!)

Is there a function to allow me to have multiple inputs for an 'IF' function, as my attempt above returned an error as 'OR' doesnt exist

Thanks

Jonathan

Another option may be to check the range and then check for certain conditions. For example, if the number has to be between 125 and 600, and must be on 25 number increments (125, 150, 175, etc.), you could do the following:

/* Check Range

IF C_GEARBOX_CD_DIM >= 125 & C_GEARBOX_CD_DIM <= 600

IF FLOOR(C_GEARBOX_CD_DIM / 25) == (C_GEARBOX_CD_DIM / 25)

XD_GEARBOX = 215

ELSE

XD_GEARBOX = 315

ENDIF

ENDIF

Jonathon,

You need to separate the staements with "|" ( shift on backspace key)

IF C_GEARBOX_CD_DIM == 125|C_GEARBOX_CD_DIM==150

'OR' is the pipe symbol '|'. You have to restate the entire expression though, not just the target values.

IF C_GEARBOX_CD_DIM == 125 | C_GEARBOX_CD_DIM == 150

XD_GEARBOX = 215

ENDIF

You can also use the '\' backslash symbol to continue to multiple lines.

IF C_GEARBOX_CD_DIM == 125 | C_GEARBOX_CD_DIM == 150 | \

C_GEARBOX_CD_DIM == 175 | C_GEARBOX_CD_DIM == 200 | \

C_GEARBOX_CD_DIM == 225 | C_GEARBOX_CD_DIM == 250 | \

C_GEARBOX_CD_DIM == 275 | C_GEARBOX_CD_DIM == 300 | \

C_GEARBOX_CD_DIM == 325 | C_GEARBOX_CD_DIM == 350 | \

C_GEARBOX_CD_DIM == 375 | C_GEARBOX_CD_DIM == 400

XD_GEARBOX = 215

ENDIF

AND is the '&' ampersand.

    Hi Tom,

    Thank you very much for your responses (and Art!)

    The CD dimension is from an imperial decimal number.

    IE my datasheet has fractioinal inches and it must be converted to decimal inches when entered in the parameters. there is no specific step between the possible entries so would the following work?

    IF C_GEARBOX_CD_DIM >= 125 & C_GEARBOX_CD_DIM <= 600

    XD_GEARBOX = 215

    ELSE

    IF C_GEARBOX_CD_DIM >= 601 & C_GEARBOX_CD_DIM <= 900

    XD_GEARBOX = 230

    ENDIF

    ENDIF

    Or perhaps write it like this instead?

    IF C_GEARBOX_CD_DIM >= 125 & C_GEARBOX_CD_DIM <= 600

    XD_GEARBOX = 215

    ELSE

    ENDIF

    IF C_GEARBOX_CD_DIM >= 601 & C_GEARBOX_CD_DIM <= 900

    XD_GEARBOX = 230

    ELSE

    ENDIF

    As an aside, will creo relations recognise fractions in parameters/

    IE if a user inputted 2 7/16 in the parameters, could creo use 2.4375 in its calculations? or is this not possible?
