I have been onto Support for 2 years now to try to get this feature put back in and this is their response.
It was decided though that this was a design function and should only be available in EST and CAD.
Unfortunately I do not have any input into what features are available or are going to be available in the software.
The worst thing is that the 3D Viewer that replaced it sort of works so the feature is still there just don't work as good!!
How can we get them to change their minds on this matter?
