I can't find the "animate dimension" command of the sketch in nx 1984. I also tried with the search but did not give me results. Yet from the attached snapshot the command exists, but I don't know what version of nx is uilized in that video.
ciao @hope , in the video it seems nx 8 or so. the command still exists but only in the 'old' sketch to what I could see. I'll send you two screenshots.
