History failed to update 1 obj

Hello - nothing in the file has history that I can see. But I suspect you want DeleteInput=Yes, that is, if you want the edge to move and not a curve copied off of it…


No, I needed the edge curve on the cplane for a reference. It must have been another obj that failed to update in the main file. I see that projecting edges does not create a history relationship. It should have though, right? ProjectToCplane is history enabled.

Help does not say that DupeEdge is history enabled, but ExtractIso is. That’s how I got around it. ExtractIso at edge, then ProjectToCplane.
