You can create a compound that just calculates the value, and then let users plug that into a Set Data themselves or alternatively create a second compound that embeds the first one plus a Set Data. I've used that approach several times. Of course, it won't work if the calculation requires an iterative execution (like the curve distance/location compounds).
Another possibility is to have output ports for both the value and the set data execution. The "display" compounds in the Debugging category are designed like that. gray From: [email protected] [mailto:[email protected]] On Behalf Of Ponthieux, Joseph G.

I was trying to make the compound do double duty as something useful as a standalone node vs a node useful to a larger tree. -- Joey Ponthieux LaRC Information Technology Enhanced Services (LITES) Mymic Technical Services NASA Langley Research Center __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party.

I've tried using first valid but it can't accept execute. I then tried an if conditional to terminate the execute channel as an option but it does not appear to be able to ignore execute whether on or off. -- Joey Ponthieux LaRC Information Technology Enhanced Services (LITES) Mymic Technical Services NASA Langley Research Center __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party.
