Logic in relations with parameters

[phirschi]

Dear community,

I would like to use the logic operations in the relation of a parts. But I have a failure message that I don't understand.

IF UNIT = G

error Logischer Ausdruck erwartet.

QUANTITY = MASSE

ELSE

QUANTITY = 1

ENDIF

Thanks in advance for you help.

If you want to compare values, you'll need to use "double equal-sign"

IF UNIT == G

   QUANTITY = MASSE

ELSE

   QUANTITY = 1

ENDIF

Hi,

Thanks for you reply. The logical test now works but I still have a failure message.

The message is in German, but it means

"Relations contain running conditions and can't be sorted by"

Thanks in advance for your help.

That is as designed by PTC.

You can NOT use "Sort Relations" if there's an "IF THEN ELSE" statement in your relations.

You just have to be very carefull writing relations, making sure they are in the correct order.

MASSE will have to be a real value.
