I think there's a bug/issue with "move face" and it not working the way I'm expecting... I don't think you can edit the feature in the way you can with other commands - basically it forgets its own history but doesn't roll-back the part.
1) new part - draw a square 10x10
2) extrude 10 to form a cube 10x10x10
3) Move Face and click on the top - add 1 to the z axis
4) measure the side and it's 11, correct.
but, now you realise you really wanted to move it 2 units, so
5) edit the move face feature (notice the previous +1 in z axis isn't listed, so you assume it's back to zero - so write a 2 in the z axis)
6) measure the side and it's 13 - wtf?!?
it's not actually rolled the part back to the start of the move-face command, but each "edit" to the feature is actually an addition to the previous result. Surely this is wrong?
Side note - the "Show Dimensions" option doesn't work either for move face - possibly linked to the above bug? if it's not actually recording each dimension then there's obviously nothing to show (if this is as design then why allow the "show dimensions" option?).
The Free Move option of the Move Face command is non-parametric, as written in the help as well.
For having the parametric behavior and the Show Dimensions working option, try to use the Direction and Distance option.
I hope it helps.
Yes, we added this capability back in Inventor 2011. You can still use the Direction and Distance or the Points and Plane (Planar Move) as in previous releases.
Cheers for the reply guys - yeah, I was using Free Move and swapping to directional gave the history/parametric-control to the command, my bad.
Ok, it's mentioned in the help file that Free Move doesn't behave parametrically, but I must applaud whoever decided that the default option for any command in a parametric modeller isn't parametric (and there isn't a warning in the dialog box) when other options are...
