simulation replay steps

[Anonymous]

how is it that in some files after simulation has run in 3D mode i can the highlite each

feature in the operation list and it will step thru in 3D in the graphics window, but in other

files it will not do this and i have changed no settings for each file?

good question, mine does the same thing. Another thing that it does that it never did before is if you simulate and then hit the save button you lose the nc code and have to run the simulation again.
